Industrial Blowers and Fans Ventilators and Industrial Ventilation

Energy recovery applications typically use two fans that provide air through a heat exchanger that “treats” the air by heating or cooling it before it enters the building. Canada Blower ’s plenum and forward curved fans are typically used for energy recovery applications and offer a wide range of performance and flexibility. Generator rooms require a wide range of fans to optimize the performance of generators and other equipment. Exhaust fans are used to prevent heat buildup within the generator room, while supply fans are used to provide fresh air for combustion and efficient generator performance. Room size, space limitations, and mounting capabilities will determine the exact type of fan needed for each specific application. As a leading manufacturer of air moving equipment, Canada Blower offers numerous fan types for meeting any generator room specification.

Industrial Pressure Blowers

Elevator shafts require proper air moving equipment to provide smoke control in the event of a fire. Pressurization is used to prevent smoke from migrating through elevator shafts to other floors, similar to how fans are used to control smoke in stairwells. Today’s elevator pressurization systems are designed to allow elevators to be used by firefighting teams. However, some systems are designed for the evacuation of handicapped individuals. While small amounts of smoke in an elevator may be tolerated by firefighters, smoke in an elevator and its entry and exit paths is unacceptable. Canada Blower ’s complete offering of smoke and heat exhaust fans are relied upon for elevator shaft exhaust/pressurization in emergency situations. Jet bridges are hallways used by passengers to board commercial airplanes. While these bridges are portable and movable, their continuous use requires an exhaust fan or gravity ventilator to prevent air from becoming stagnant. Fans and ventilators draw air into the bridge from the terminal and through the exit which is then exhausted through a fan or ventilator. Canada Blower provides a number of centrifugal roof exhausters and gravity relief ventilators for jet bridge exhaust applications.

Industrial Blowers for Ventilation

Enclosed or underground parking garages require ventilation to remove harmful vehicle emissions and other pollutants, while providing fresh air. Ventilation is also a requirement in the event of a fire to remove smoke and to provide a clear access for firefighters. Exhaust and supply fans are used in conjunction with ductwork to distribute air throughout the parking garage, providing a common system for both pollution and smoke control. Twin City Fan manufactures a complete line of axial flow fans designed for parking garage ventilation systems. Restroom exhaust fans are primarily used to reduce moisture and prevent mold buildup. As restrooms typically occupy a small space, restroom exhaust fans are considered low volume and generally provide 2 to 5 air exchanges per minute. These fans are mounted on the roof or in-line with the system’s ductwork. Canada Blower offers a full line of centrifugal roof & wall exhausters, inline centrifugal fans, and ceiling & cabinet ventilators to accommodate all restroom requirements and exhaust applications.

Industrial Inline Exhaust Fans

Rooftop exhaust fans are designed to remove heat and odors from buildings to improve air quality and occupant comfort. Areas such as cafeterias, locker rooms, office spaces, restrooms and warehouses often have unique requirements specified by local codes and utilize a wide range of rooftop exhaust fans. To accommodate these various types of environments and ventilation systems, Canada Blower Fan offers a complete line of products to support every rooftop exhaust application. These applications can range from clean airstreams with minimal filtration all way to high density offices and health care facilities that must comply with extremely stringent regulations. Gravity ventilators are used to equalize a building’s positive or negative pressure created by other fans in the system. These ventilators provide natural ventilation and are used for intake and relief applications. Canada Blower Fan offers both spun aluminum and hooded ventilators, featuring a low silhouette for low roof-lines. Louvered penthouse ventilators are available when aesthetics are not an important factor and feature extruded aluminum louvers. Sidewall exhaust and supply applications require panel fans to move large volumes of air at low static pressures. Panel fans are commonly used on the walls of warehouses and manufacturing facilities to supply outside air or to remove hot or noxious gases in exhaust configurations. Other typical applications include removing carbon dioxide from produce storage facilities, greenhouse ventilation, and parking garages. Panel fans can be mounted directly to the wall panel, which is especially useful when ductwork is unnecessary. Each fan can be customized to the individual needs of the customer, including aluminum or stainless steel construction, explosion proof motors, gravity or motorized dampers, corrosion resistant coatings, and fully reversible propellers.

Industrial Fans

Indoor swimming pools require air moving equipment for exhausting moisture-laden, corrosive and chlorinated air. Fans and duct systems must be designed to withstand these elements. That is why Canada Blower offers a wide selection of fans and construction materials, including fiberglass, alloys, and specialty coatings to prevent the potential corrosion associated with these environments.

Industrial Ventilator Blowers & Fans

Ventilation is a crucial component for any mining operation. Inadequate ventilation can expose miners to high levels of dangerous gases, dust particulates, and excessive heat. The consequences of prolonged exposure to these elements can pose a series of health related complications. We understand the significance of selecting the right ventilation equipment for maximizing the air quality in mines, which is why Buffalo Blower offers a comprehensive line of products suited for the most rigorous mining ventilation applications. We also offer many special design features such as non sparking units, explosion proof motors and specialty guards. Stairwells are frequently the primary escape route in the event of a fire emergency and may also serve as the primary access route for firefighting teams. In these smoke control zones, fans are used to pressurize stairwells to limit smoke infiltration by maintaining positive pressure across closed stairwell doors. Fans used for stairwell pressurization are designed to operate at low enough pressures so that doors can be safely opened during evacuation. Because occupant safety is the most important aspect when facing a fire emergency, Buffalo Blower offers a complete line of smoke and heat exhaust fans designed for stairwell pressurization.

Industrial Pressure Blower Fans

Service stations require vehicle exhaust systems to maintain indoor air quality for customers and employees. These systems attach to a vehicle’s exhaust pipe to draw hazardous emissions out of the building. The fans used in these systems are attached to small hose and must be capable of producing high pressures due to the air velocity required to exhaust the fumes. Buffalo Blower offers a wide selection of compact pressure blowers and radial bladed fans capable of meeting the high pressures requirements of vehicle exhaust systems.

Industrial Blowers and Fans — About Air Handing Fans

Since July 1, 2003, equipment manufactured for operation in potentially explosive environments has been required to comply with the European Directive 94/9/EC. This directive, commonly referred to as the ATEX Directive, applies to all countries in the European Union (EU) and the European Economic Area (EEA). The ATEX Directive is a collection of EU directives outlining equipment installed and operated in potentially explosive atmospheres. The ATEX directive coordinates various technical and legal conditions throughout Europe to ensure a high level of safety for the end-user by reducing the explosion risk through established design methods. The European Committee for Standardization (CEN) published EN 14986 as a standard specifically for the manufacture of fans for use in hazardous areas. This standard is a guide specifically for fan manufacturers to comply with the ATEX Directive.

Industrial Blowers & Fans – Air Handling Units

Air Handling Units (AHU) combine a fan (or several fans) with other components such as heating and/or cooling elements, filters, and dampers as a means to collectively condition the air in a building. AHU is a general term comprised of many specific types of air handlers including: Make-Up Air Units (MAU), Packaged Units (PU), Rooftop Units (RTU), and Energy Recovery Units (ERU). Air handlers range from very small, low CFM light-duty construction to very large, high CFM heavy-duty construction, and are used in many types of buildings that require air conditioning such as office buildings, hospitals, universities, schools, manufacturing facilities, and data centers. Typically, air passing through an AHU is clean and varies in temperature depending on the specific application. Energy consumption and noise are often important considerations when selecting a fan for an AHU. Plenum fans and DWDI fans are commonly found in these units, but are not used exclusively. To accommodate the various applications these units are used for, Canada Blower offers the most diverse and efficient fans in the industry to meet the need of any air handling unit.

Industrial Blowers, Propeller Fans & Blower Fans

Industrial electric fans clearly do not use as much electricity as an air conditioner, circulating air and cooling it at a fast rate for a large space. With high-powered, energy-efficient motors, the larger motor of an industrial fan is actually guaranteed to save energy costs.

Industrial Blowers and Fans for Cooling

Air conditioning can often become too large of an expense for industrial areas, but the good news is that an industrial fan can bring some much needed relief in this case. Industrial electric fans can be quite helpful for places where heat stratification, dampness, and stagnant air become frequent problems. Also, for high static pressure an industrial fan is what you need. Also known as an industrial electric blower, these units replace air as well by blowing out the old and stagnant air for a wide area that otherwise would collect this air without replenishing it in entirety.

Industrial Blowers and Radial Blower Fans for Ventilation

Industrial warehouses, especially profit from these large units because the fans can support a higher CFM rating without the vibrations of a smaller fan. Most electric industrial fans have blades of a higher more durable construction, usually consisting of some kind of metal. This allows the blades to move more air at one time without all the force being applied to the fan and making the motor work harder.

Industrial Blowers & Fans Types

Industrial fans include several types such as duct fans, roof and ceiling ventilators, wall mounted fans, pressure blowers, and freestanding units with different mounting options. For extreme conditions and plants, drum fans can be used to move even larger amounts of air. These types of fans come with wheels attached and can be rolled to the area that circulation is needed the most. Some manufacturers even sell just the fan heads for a more freedom and a reduced assembly and cost on the company.

Versatility of Industrial Blowers and Fans

Powerful motors for reducing excessive noise are used in industrial fans. The motor will not be working at its top speed to produce the necessary airflow, therefore it will be quieter. Industrial electric fans are also very versatile; there are floor fans, wall mounted fans, and pedestal fans that all come in industrial grades. If you plan on a very large space, a pivoting fan is a good choice as you can manipulate the direction of the air and direct it to where it is needed most. Some even come with stands to make these larger fans easy to roll from place to place.

Industrial Fans & Blowers Efficiency

These motors are designed to change a large amount of electrical energy into useful fan work. Often as electric industrial fans are in operation for an entire day period, opposed to a home fan which is turned on only when people are home, or in a specific room, the industrial fan needs to be energy efficient for this extra use. These motors can handle more heat than a normal motor meaning less heat waste is produced. If you think you need an industrial fan for your business area, chances are that you do! Make the choice today for comfort and health and consider an industrial fan purchase.

Industrial Centrifugal Blower Fans & Axial Fans

Backward Inclined Blowers

Backward Inclined Fans – Simple flat blades, but backwardly inclined to match the velocity pattern of the air passing through the fan wheel, which results in high-efficiency operation. These fans are typically used in high-volume, relatively low-pressure, clean air applications.

Centrifugal Blower Fans

Airfoil Centrifugal Fans are used for a wide range of applications in many industries, hollow-bladed airfoil fans are designed, engineered and tested for use in airstreams where high efficiency and quiet operation are required. They are used extensively for continuous service at ambient and elevated temperatures in forced and induced draft applications in the metals, chemical, power generation, paper, rock products, glass, resource recovery, incineration and other industries throughout the world.

Backward Inclined Blower Fans

Backward Curved Fans – Efficiencies nearly as high as the airfoil design. However, single-thickness metal blades prevent the possibility of dust particle buildup inside the blade. These fans can be built with long-lasting erosion-resistant liners. The robust design allows high tip-speed operation, and therefore this fan is often used in high-pressure applications. This design frequently offers the best compromise for long life and high efficiency.

Radial Blade Blowers

Radial Blade Blowers – Flat blades oriented in a radial pattern. These rugged fans offer high pressure capability with average efficiency. They are often fitted with erosion-resistant liners to extend the rotor life. The housing design is compact to minimize the floor space requirement.

Forward Curve Blower Fans

Forward-Curved Radial Tip Fans – This rugged design is used in high-volume flow rate applications when the pressure requirement is rather high and erosion resistance is necessary. It offers medium range efficiencies. A common application is the dirty side of a baghouse or precipitator. The design is more compact than airfoil, backward curved or backward inclined fans.

Industrial Blowers

Paddle-Wheel Blowers – This is an open impeller design without shrouds. Although the efficiency is not high, this fan is well suited for applications with extremely high dust loading. It can even be offered with field-replaceable blade liners from ceramic tiles or tungsten-carbide. This fan may also be used in high-temperature applications.

Forward Curve Blowers

Forward-Curve Fans – This “squirrel cage” impeller generates the highest volume flow rate (for a given tip speed) of all the centrifugal fans. Therefore, it is often the smallest physical package available. It is commonly used in high-temperature furnaces.

Industrial Exhaust Fans

Industrial Exhausters – Relatively inexpensive, medium-duty, steeply inclined flat-bladed fan for exhausting gases, conveying chips, etc.

Pre-Engineered Blade Blower Fans

Pre-engineered Fans – are series of fans of varying blade shapes that are usually available in only standard sizes. Because they are pre-engineered these fans may be available with relatively short delivery times. Often, pre-engineered rotors with various blade shapes may be installed into a common housing. These are often available in a wide range of volume and pressure requirements to meet the needs of many applications.

Industrial Pressure Blowers

Pressure Blowers – High-pressure, low-volume blowers used in combustion air applications in furnaces or to provide “blow-off” air for clearing and / or drying applications.

High Pressure Blowers – Surgeless

Surgeless Blowers – High-pressure, low-volume blowers with a reduced tendency for “surging” even at severely reduced flowrates. This allows extreme turndown (low-flow) without significant pulsation.

The main types of Axial Flow Fans include:

Axial Fans – High Temperature

High-Temperature Axial Fans – High-volume fans designed to operate against low flow resistance in industrial convection furnaces. These are found in either single-direction or bi-directional designs. Extremely rugged, they are most often used in high-temperature furnace (up to 1800 degF) applications.

Tube Axial Fans

Tube Axial Fans – Cataloged high-volume low-pressure fan line with a wide range of available sizes. Suitable for temperatures up to 250 degF.

Vaneaxial Fans

Vaneaxial Fans – Axial flow fans with higher pressure capability due to the presence of static vanes.

Variable Pitch Axial fans

Variable Pitch Axial fans – Axial fans with manually adjustable blade angles. This allows operation over a much wider range of volume/pressure relationships. The blades are adjusted periodically to optimize efficiency by matching the blade pitch to the varying conditions for the application. (Often used in mining applications).

Variable Pitch on-the-fly Axial Fans

Variable Pitch on-the-fly Axial Fans – These are similar to “Variable Pitch Axial Fans” except these include an internal mechanism that allows the blade pitch to be adjusted while the fan rotor is in motion. These versatile fans offer high-efficiency operation at many different points of operation.

Variable Speed Fans

Variable Speed Fans – All of the fans described above can be used in conjunction with a variable speed driver. This might be an adjustable frequency AC controller, a DC motor and drive, a steam turbine driver, etc. Flow control by means of variable speed is typically smoother and more efficient than by means of damper control. Significant power savings (with reduced cost of operation) are possible if variable speed fan drives are used for applications that require reduced flow operation for a significant portion of the system operating life.

Centrifugal Industrial Blowers – NISCO Blowers and Fans

Centrifugal fans employ the use of a rotating impeller to increase the speed of air stream. The centrifugal speed increases as the air stream reaches the ends of the fan blades and is then converted to pressure. These fans are able to produce high pressures, making them suitable for harsh operating conditions, such as:

* Systems with high temperatures
* Moist or dirty air streams
* Material handling/conveying

Northern Fan Co. has considerable experience with air moving applications. Fans are the “heart” of all ventilation systems, and essential for all industrial processes that require air flow. Northern Fan Co. application experience with nyb fans and blowers is pivotal to the success of a complete air handling package and includes:
