Applications for Corrosion and Chemical Resistant Fans include:

* University, Medical Research, Defence Labs, Fume Hoods OEMs, Pharmaceutical Labs

On most campuses there is a certain number of fume hoods that are used for various acids testing to break down materials for analysis. HCl and Perchloric Acid are the ones used most commonly. Fume hoods and Chemical resistant fans are needed.

* High Technology Semiconductors, PCBs, and Photonics

Chip makers use acids to clean metal before they mount thin film on the metal upon which they lay circuitry.

* Printed Circuit Board Industry

FRP fans are frequenly used for clean rooms.

* Waste water and Sewage Treatment Plants

Hydrogen Sulfide builds up (H2S) in sewage plant facilities and causes an odor problem that has to be treated. Depending on the size of these stations corrosion resistant fans are needed. This gas can also be very volatile and will require explosion proof motor and static grounding of the fan housing by graphite impregnation that Northen Industrial Co. can provide too.

* Salt Air and High Humidity Environments

Any facility near the salt air is also a good place for plastic fans and the humidity will eat through metal fans.

* Steel and Wire Manufacturing

As the steel comes in and sits at these plants impurities and scale develop on the steel or the wire that needs to be cleaned off before the wire or steel can be properly worked with. Acid baths are needed for this and the corrosive fumes coming off these aced baths are highly corrosive…

* Stainless Steel and other Metal Production Facilities

In tha annealing and Pickling process acid baths are used to strip scale off the steel after the annealing process that smoothed out grain patterns that may have formed during the annealing process. Later on acids are used again to support oxidation.

* Chemical and Petrochemical Industries

* Jet Engine and Power Plant Turbine Manufacturing or Servicing

Molted Salt tanks are often used here to descale metals coming out of hot furnaces. Pickling and cleaning of titanium which is used in Jet engine parts also utilize acid baths as does nickel plating.

* Electroplating and Metal Finishing

These industries use fiberglass fans and fume scrubbers.

* Scrubber OEMs and Designers

FRP fans are standard components in fiberglass srubber designs.

* Industrial Galvanizers

* Printing Press Service Shops

* Chromatography

* Food Processing

Often in the food processing industry they wash equipment down with acids and other corrosives. Also they use fans for the humidity that builds up from the drying process of foods.

Exhaust Fans & Inline Fans for Residential Ventilation

Most of today’s new homes are highly insulated and practically air tight. While this is great as far as cost effective energy bills go, the down side to tightly insulated homes is poor indoor air quality. As windows and doors are typically kept shut throughout the day, moisture, and stale air that can carry contaminants and pathogens circulates inside homes and gives rise to various problems including mold and mildew, health problems, ruined furniture, peeling paint etc. This is why it is important that you take every step to improve the quality of your indoor air, which can be achieved through mechanical ventilation.

An excellent way to ventilate your home thoroughly, efficiently, and cheaply is to install exhaust fans in your home. This article explains what exhaust fans are, their different types, how to select the best one for your home, and also the benefits of exhaust ventilation fans.

What Are Exhaust Fans

An exhaust fan is a mechanical ventilation device that helps to draw out stale and impure air from your home and bring in fresh air, thereby improving the quality of indoor air. Exhaust fans are typically ducted to the exteriors of your house, through which bad indoor air can effectively be removed from your living space.

Types Of Exhaust Fans

Exhaust fans are classified into various types, mainly depending on the type of mount and the location where you need to install the fans. The different types are:

1. Ceiling Mounted Exhaust Fans: As the name suggests, ceiling exhaust fans are those which are installed in the ceiling. Such fans expel stale air from your home upwards through the roof. The fan is connected to ducting, which is exhausted outside the home via an external vent, like a roof cap or soffit exhaust vent.

2. Inline Exhaust Fans: Unlike ceiling exhaust fans that are installed directly into the ceiling, inline exhaust fans are typically mounted in-between ducting, hence the name inline fan. For instance, if you wanted to ventilate an area that did not have clearance or space for a ceiling mount fan, you would make use of inline exhaust fans to ventilate such areas. The exhaust fan would be placed in between the ductwork and the stale air would travel through the ducts and ultimately be expelled from your home. Since inline fans are not mounted directly to the ceiling, they are very quiet. When installing an inline fan, to reduce noise, we recommend using an insulated flex duct that is at least eight feet long from the intake port on the ceiling to the inline fan.

Inline exhaust fans are ideal for exhausting areas or rooms where you cannot, or do not wish to install the exhaust fan directly. Since these types of exhaust fans are mounted in remote areas, they are also referred to as remote mounted exhaust fans. Inline exhaust fans can either be single-port (exhausting from a single area) or multi-port (exhausting from multiple areas).

3. Wall Mounted Exhaust Fans: These exhaust fans are installed on walls. Since they are installed on exterior walls of the home and not on interior walls, the stale air has a direct route to the outside of your home and thus no duct work is required in installing these exhaust fans.

4. Combination Exhaust Fans: Exhaust fans are also available as combination units. You have the choice of a fan-light combination where the exhaust fan provides illumination as well, or heat-fan-light combination wherein you get a heater, light and ventilating fan all in a single device.

5. Exterior Remote Mounted Exhaust Fans: While most other exhaust fans are installed inside your home and push stale air out, exterior remote mounted fans are installed outside your home and pull out stale indoor air instead of pushing it out. The main benefit of these exhaust fans is that regardless of however noisy they are, most of the noise remains outside your home.

6. Kitchen Range Exhaust Fans: These fans are mounted inside the range hood over your kitchen stove. Such fans not only help to rid your kitchen of stale air but also help to expel bad odors and reduce moisture levels in your cooking area.

These several types of exhaust fans can be used for complete ventilation of your home including intermittent local ventilation for baths, kitchens, dryer rooms; continuous whole house ventilation throughout your home, and for exhausting hard-to-air spaces such as crawl spaces, attics, and basements.

Benefits Of Exhaust Fans

Exhaust fans are very effective at ventilating your home and other living spaces. Without proper ventilation, the air inside your home can get filled with harmful contaminants and disease causing pathogens.

Pollutants such as pesticides, harmful gases, smoke, pet dander, lead, asbestos, dust mites, paint fumes, grease etc get released into indoor air due to daily activities such as cooking, smoking, burning fuel, bathing, renovating etc. In addition to these pollutants, activities such as bathing, cooking, and washing also release excess moisture in the air and make indoor air extremely humid. If not ventilated adequately, these added pollutants and increased moisture levels can decrease the quality of indoor air greatly, thereby leading to various problems such as:

Health problems including asthma, allergies, nose bleeds, skin rashes, headaches, nausea, and other breathing disorders. In fact, according to the Environmental Protection Agency, a large percentage of the over 20 million annual asthma cases in the US alone can be attributed to bad indoor air quality.

Split, warped and rotted furniture due to excess humidity.

Cracked and peeling paint on the walls.

Formation of fungus, mold spores, and mildew, which in turn lead to severe health problems.

Thus, by using exhaust fans to ventilate your home efficiently and completely, thereby improving indoor air quality, you can rid yourself and your home of all these problems.

Recommended Sizing Of Exhaust Fans

To ventilate your home effectively, it is important that the exhaust fan you choose has the capacity to exhaust the intended space completely. To ensure this, you must select the right sized fan for your needs. Here’s a look at how to size exhaust fans properly.

1. Location of the Exhaust Fan and Air Changes Per Hour:

Where you intend to install the exhaust fan will have a direct bearing on its size. As per the Home Ventilating Institute (HVI), different locations in your home require varying Air Changes Per Hour (ACH) in order to be ventilated properly. Here are the ACH requirements recommended by HVI.

8 ACH for bathrooms

15 ACH for kitchens

6 ACH for rooms other than bath and kitchen

ACH refers to the number of times the air should be completely changed in an hour. Thus, an 8 ACH recommendation for bathrooms means the exhaust fan should have the capacity to completely change the air in the bathroom 8 times in one hour.

All exhaust fans are rated in CFM, which refers to Cubic Feet per Minute. To determine how large an exhaust fan you need (in other words, CFM rating of the fan) here’s what you need to do.

Sizing Bathroom Exhaust Fans:

First and foremost, measure the dimensions (length, width, and height) of the room and then calculate the volume of air in the room by multiplying all these 3 numbers. For instance, if your bathroom has dimensions of 6 x 10 x 8, then the air volume in the bathroom is 480 cubic feet. Thus, the exhaust fan needs to ventilate 480 cubic feet of air in order to achieve 1 ACH. But since the recommended ACH for bathrooms is 8, the fan will effectively need to ventilate 480 x 8 cubic feet, which equals 3840 cubic feet in one hour. Fan ratings are per minute, thus by dividing 3840 by 60, you can achieve the desired CFM rating for the fan which in this case is 64.

A simpler way of determining the CFM rating for bathroom exhaust fans is to simply multiply the length of the bathroom by its width. For every 1 sq. ft. of floor area, you need 1 CFM. Thus, in the above example, area would be 6 x 10 = 60, thus recommended fan size would be 60 CFM.

However, if your bathroom is more than 100 sq. ft. in size, you have to add the different fixtures in your bathroom to reach the desired CFM rating. The recommended CFM for different fixtures is:

· Shower – 50 CFM

· Toilet – 50 CFM

· Bathtub – 50 CFM

· Whirlpool tub – 100 CFM

Thus, if your bathroom is more than 100 sq. ft. in size and has a toilet and shower, you will need an exhaust fan with 100 CFM rating. If a bathtub is also present the CFM rating will increase to 150 and so on.

Sizing Kitchen Exhaust Fans:

When sizing an exhaust fan for the kitchen, you have to take into account the location of your kitchen cooking range (if without range hood) or the size and location of the range hood if there is one. Here are the recommended CFM ratings for kitchen range hood exhaust fans:

Generally speaking, for every 10,000 BTU of the range, it is recommended a minimum of 100 CFM. So if your range is rated at 50,000 btu’s, you would consider getting a fan with at least 500 CFM.

2. Understanding Static Pressure and Measuring Equivalent Duct Length:

When sizing an exhaust fan that does not open directly to the outside but is ducted, it is important to ensure that the exhaust fan has the capability to move stale air throughout the duct and ultimately to the outside. Here, we first need to understand what static pressure and equivalent duct length is.

Static Pressure: Inside every duct, there is a constant pressure being exerted at any point from all directions. When an exhaust fan moves air through the duct, the air counters resistance from this pressure which is known as static pressure. Thus, an exhaust fan has to have the ability to overcome the static pressure in a duct so as to effectively duct stale air to the outside of your home. This can be done by calculating the equivalent duct length of any duct.

Calculating Equivalent Duct Length (EDL): Simply measuring the length of a duct is not enough to know how much static pressure an exhaust fan has to overcome. Ducts may have one or more elbows, turns, or wall caps which add to the static pressure in a duct. Thus, you have to calculate the equivalent duct run and not the actual duct run so as to size an exhaust fan properly.

The static pressure in any duct run differs according to the material of the duct, number of elbows and turns, exterior wall cap and wall jacks etc. Listed below are the standard values for different duct components.

Smooth metal duct: Actual duct length x 1

Flex aluminum duct: Actual duct length x 1.25 (for 4″diameter duct)

Actual duct length x 1.50 (for 6″diameter duct)

Insulated flex duct: Actual duct length x 1.50 (for 4″diameter duct)

Actual duct length x 2.00 (for 6″diameter duct)

Wall caps and roof caps: 30 feet for each cap (for 4″diameter duct)

40 feet for each cap (for 6″diameter duct)

Elbows and turns: 15 feet for each (for 4″diameter duct)

20 feet for each (for 6″diameter duct)

Using the above values, you can calculate the equivalent straight duct length that an exhaust fan has to overcome so as to push stale air outside your home and counter static pressure effectively.

Industrial Fans for Cooling

Industrial cooling fans are useful for a number of businesses and industries. If you or your any family member operates a parking center, then you need these types of fans to keep the unit well ventilated. An industrial cooling fan has been considered as an efficient means of air circulation to thwart people being overcome by fumes from exhausts, etc. People involve in transporting livestock from one location to another must require these fans as heat can cause damage to your animals. It is your duty to keep your animals relaxed as they are completely dependent on you for their well-being.

People involve in operating a warehouse or a loading dock face a number of problems to keep the temperature in control. They must need to introduce a comfortable working environment so that their employees can work and live in with comfort and peace. Sometimes, normal air conditioning or heating systems can be proved as an expensive option so that people are advised to look for industrial cooling fans. Apart from circulating the air and moving the hot or cold air around the building, the expenditure of running fans combined with a heating and air conditioning system seems to be cheaper than a standalone HVAC system.

If you are an employer and working in a number of industries, then your first duty is to take care of your employees by providing comfortable working surroundings. It doesn’t signify you have to provide a lot of fancy couches and comfy seating, but it does exhibit that you cannot expect a person to work in overheated conditions. In fact, an employer needs to provide decent air quality and conditions for his/her employees to work in. These are the reasons for which the demand of industrial cooling fans has been increased to the great extent.

To purchase an industrial cooling fan, customers need to consult online stores. A simple search through the internet brings them a number of online stores selling the products and services at affordable rates. In addition to their products, their services are unique and exclusive in the market. So, it is advised to make search and see results.

The Various Applications Where Ventilation Fans Are Used:

•The Ventilation Fans are extensively used in various activities such as, fabricating, manufacturing, mining, etc. These Ventilation Fans are used for the removal of dust, fume, and smoke particles from the atmosphere and to make it free from suffocation. Some of the manufacturing units where the Ventilation Fans are used for the mass extraction of fumes and dust particles are, Textile Mills, Steel Mills, Wood product Mills, Ceramics and Aerospace material units. These units install huge turbines and impellers to move the extremely large volume of air.

•Crude Oil and Petrochemical Refineries have to deal with fuels and solvents which are extremely toxic, flammable, and unpredictable. Here, Ventilation Fans are required for the functioning of sophisticated Air Entrainment systems.

•The Mining and Quarrying industries are always immensely reliant on the Ventilation Fans. The Coal dust in these mines can be very explosive if it somehow catches fire. This risk is reduced by the dust removal, which is done by the Ventilation Fans. Very powerful blowers and bulky turbines are implemented to ventilate the mines and quarries.

•The workers in Biological, Chemical, and Pharmaceutical industries have to struggle with biological, chemical, and various other physical risks. In such environment, Ventilations Fans come to their rescue.

Attic Fans

While most households are conscious on the convenience brought by nicely ventilated homes, many tend to overlook the attic as one of the areas to be considered. No one finds it comfortable staying for long hours in the closed attic because of the overwhelming heat that builds up in it. For this reason, it is necessary for everyone to consider installing attic ventilation fans in order to cool down the attic’s heat. This can have amazing advantages to the overall household convenience while minimizing energy costs.

Attic fans are, without a doubt, effective tools in bringing ample air exposure to the attic. Without these, all the heat from the sunlight is absorbed into the house even without bringing noticeable change to the temperature. The same thing happens even when the days are not too sunny. All the heat absorbed from its daily encounter with direct sunlight is trapped inside the attic. Not only that, since warm air naturally rises, all the heat in the house goes up to the attic. This can result to a throttling discomfort for anyone who goes in the attic to either look for something in the storage or to bring over new belongings for keeping.

Improper attic ventilation

Improper attic ventilation also has negative effects to things stored there. Too much heat can be bad for the things kept in the storage. It will gradually diminish their quality and can even damage those fragile and sensitive possessions. Moreover, the overly high temperature in the attic can result in the breaking of the house’s roof. Although these do not happen overnight, the effects will be noticeable in due time. The costs of replacements and repairs will only add to the family’s expenses. This is one of the reasons why mounting attic ventilation fans are necessary.

These attic fans also help minimize the development of excess moisture in the room. Lesser room moisture means it becomes impossible for molds and yeast to grow in the sheaths and frames under the roof especially on summer months. This is applies to both warm and cool seasons. For colder times, the cooling effects of attic ventilation fans are very helpful in preventing ice blocks from expanding on the rooftop. This protects the roof from being damaged by the ice.

There are many types of attic fans being sold in the market nowadays. However, using the solar types is highly recommended because of their economical value. These solar fans not only save on the electric bills but also reduce the amount of energy emitted by electronic appliances which are harmful to the environment. They are also as competent as the plug-in types of fans. While this choice of attic ventilation fans are more expensive compared to non-solar ones during the initial purchase, one cannot deny its long-term cost-efficiency.

People tend to neglect the importance of having a well-ventilated attic. Although it is just an extra space mostly utilized for storage, it significantly has effects on the amount of heat stored in the residence that has some lasting drawbacks to the house and the things kept in the attic. Therefore, it is important to take time to evaluate the attic’s ventilation needs and install efficient attic fans.

Industrial Air Curtains

The idea of having an invisible barrier across the doorway to enable unimpeded access yet effectively prevent temperature flow, dust, odours and insects to cross, is appealing in itself but add to this the cost-saving in reducing energy use and the idea becomes more compelling, especially as air curtains are relatively inexpensive items.

Appropriate for industrial applications

Keeping warm air out of insulated cold stores or refrigerated facilities is the Number 1 objective yet a mockery is made of this premise when freezer of chiller doors are left wide open and, in some cases, chocked open to facilitate the movement or storage of perishables.

Self-generated pressure evolves from a non-circulatory type of air curtain as the jet induces ambient air into the stream. When the air curtain is installed on the outside of a cold room, the air spills back into the room and continues to do so until the pressure builds up to such a point that the air stream deflects to the outside.

Pressure Form Stack

The pressure-form-stack effect evolves when the cold air in the room is denser than the warmer outside air. The higher the ceiling, the higher the pressure becomes inside the cold room. The velocity of the air curtain should therefore be high enough to compensate for the outward pressure at the lower part of the cold room.

Wind pressures occur because of the conversion of the velocity pressure in the wind into static pressure. Of particular significance is the stability of the air curtain, which is directed by its outlet momentum. The curtain of air must be able to withstand pressure variations between the inside and the outside of the cold room. The outlet momentum should be sufficiently sustained and strong enough to stabilise the air at the floor. It is therefore essential to incorporate controls in the design of the air curtain to increase the strength of the velocity and ensure a stiff curtain of air and to decrease the velocity to prevent unnecessary heat and moisture transfer at the door.

Refrigeration Applications

In refrigeration applications, a high volume of turbulent air hitting the floor tens to form ice on the floor of freezers – this is not desirable or necessary so air flow needs to be adjusted so that it barely hits the floor. This can be accomplished by adjusting air louvers or fan speed to obtain the desired velocity. Drafts are eliminated by ensuring that air flow is vertical. The air curtain may be mounted on either the warm or cold side of the cooler with equal effectiveness.

The volume of air flow varies according to temperature difference between internal and external air and air exchange is therefore caused by thermal temperature differences. Using known values for the indoor and outdoor temperature difference, the densities, pressure differences and ultimately the air flow through the opening can be calculated.

Properly installed air curtains cut cold air loss and reduce humidity, thus reducing the load on refrigeration or air-conditioning plant and thereby saving energy by reducing compressor running time, maintenance, gas and recharging intervals. These units are an alternative to fast-acting roller doors and PVC slat curtains, and can be situated above or to the side of industrial doorways to create a powerful seal across the opening, keeping cold air in while providing complete visibility and access. This means that forklift drivers don’t have to get out of their cabs to open and close doors so that moving from one area to another is a lot easier and productive. Unlike plastic slat curtains, which quickly become opaque with use, an air curtain provides 100% visibility at all times. Units have been installed in loading bays, factories, hangars and production facilities, such as food processing and pharmaceuticals, where differential temperatures are encountered overseas.

Canadian Air Systems Co. is a well known designer and manufacturer of industrial and commercial air curatain systems and environmental air barriers.

For special applications Canadian Air Systems offer tangential air curtains to achieve high volume alminar air flow – to create permanent environmental air barriers.

Industrial Screw Blowers

Industrial standard ISO-1217 requires the performance of the blower to be measured at the blower outlet. This is a far more accurate indication of the performance of the blower and clearly qualifies the air volume that is available to the aeration system. That is the reason why, for instance, our company provides data for its low pressure screw blowers’ in line with the ISO1217 standard, which requires the performance of the blower to be stated as FAD (Free Air Delivery) – the actual volume of air at the
blower outlet.

From an operational standpoint, it may not always be appreciated that when comparing the energy efficiency of different blower technologies the performance data may not be presented in a comparable manner. For example, lobe blower performance data is commonly offered by indicating the air intake flow volume and the energy used at lobe element shaft, not the actual volume of air the blower package delivers – the net usable air – and not the energy consumption including all the blower package power losses.

This anomaly is all the more surprising when it applies to waste water aeration process operations. In order to maintain the desired oxygen level within the aeration lanes, the precise volume of the aeration air being supplied by the blowers is a critical factor in sustaining the aerobic process. It is for this reason that the latest revision to the Water Industry Mechanical and Electrical Specifications (WIMES) for low pressure blowers has included measuring the blower performance according to the ISO 1217 standard, reflecting the evolving needs of the water industry.

From a technical perspective, the lobe blower has to work harder and therefore less efficiently because the delivered air is compressed externally and depends on back pressure from the connected pipeline (and from water resistance in the aeration tank) to maintain the required air flow and pressure. By contrast, the rotary screw type blower demands less energy because the internal compression concept offers higher efficiency. This becomes even more significant when there is a variable aeration demand; the screw blower exhibits a more consistent volumetric efficiency derived from the design of the rotor elements.

When comparing blower technologies a true package power evaluation should be made. The factors to be considered should include the pressure drops within the blower, transmission losses: belt drive compared to direct drive, motor efficiency and, of course, the air volume at the blower outlet versus the total package power input.

On face value, the lobe blower may appear to offer plant operators a simple, low cost, basic option for low pressure air applications. The reality is that in a low carbon economy many industrial applications can benefit from improved performance and significant energy savings through the replacement of conventional lobe equipment with innovative and sustainable, screw technology solutions.

The increased emphasis on the ISO 1217 standard in providing flow figures from a blower will ensure that operators are provided with a truer picture of blower efficiency and the FAD volume of air that is supplied to their processes.
