The NIS-CO Blowers Plug-Pak fan is of all welded construction and engineered to simplify installation and minimize maintenance requirements. The Plug-Pak can be installed in walls, floors, ceilings or plenums.

The Plug-Pak offers non-overloading characteristics with welded steel structural members which increases rigidity and stability of operation while saving space and cost.

The basic Plug-Pak unit consists of a backward blade wheel overhung on a shelf that is supported by two bearings mounted on an external base.

The standard units are built to operate in temperatures up to 300^oF. For temperatures in excess of 300^oF to a maximum of 800^oF a 4" insulated plug and a heat slinger are available as optional accessories.

Wheel diameters from 12-1/4" to 49", Class I or II are available. The Plug-Pak fans produce air volumes to 53,820 CFM and 8" static pressure.

The Plug-Pak is available for either horizontal or vertical mounting with or without scroll housing.

NOTE: Wheel diameters 12-1/4" thru 24-1/2" are flat bladed construction. Wheel diameters 27" and up are available in either flat bladed or airfoil bladed constructions.

STATIC AND DYNAMIC BALANCING

Completed wheel assemblies of all sizes are statically and dynamically balanced on electronically controlled balancing machines. The necessary weights are arc welded into place so that the wheel will always stay in balance.

After the complete blowers are assembled, they are all given a running in inspection and again examined for balance by a portable electronic balancing unit. Inspectors add balance weights to the wheel if necessary to pass a very rigid requirement.

PLUG FAN SELECTION (EXAMPLE WITHOUT HOUSING) 6704 CFM @ 2.5 TSP (System) installation is a two-wall arrangement with a wheel-to-wall clearance of 63/4 inches.

Step 1. Entering the performance tables, we find that a PG270AF will deliver 6704 CFM @ 2.5 S.P. operating @ 1050 RPM with 3.85 BHP.

Step 2. Catalog performance must be corrected for wheel-to-wall arrangement. Determine the wheel and Plenum type from the arrangements shown above. (Arr. #2 used for this example). Determine the

clearance ìCî based upon the closest wall. Performance will not be affected by any additional walls spaced greater than 3 times the ìCî dimension being used. The selected PG270AF fan has a wheel diameter of 27 inches. Application is therefore C/D = 6.75?27 = 25% of wheel diameter.

Corrected unhoused performance for 6704 CFM @ 2.5 SP standard air is RPM = 1050 x .97 = 1019 BHP – 3.85

x .99 = 3.81.

For performance of units with a housing for sizes PG122BC thru PG245BC, refer to the POWER FIXED BLOWERS Catalog.

For sizes PG270AF thru PF490AF, refer to the POWERFOIL BLOWERS Catalog.

TYPICAL INSTALLATIONS

Plug Fans offer versatile applications to ovens, packaged air handlers, penthouses, ceiling, wall, and floor panel plenums. Unit assembly may be mounted with shaft in either the vertical or horizontal position. Space savings can be obtained by utilizing the wheel compartment as a pressurized chamber in lieu of a fan scroll. The use of multiple discharges from the pressurized chamber allows for additional savings by reducing ducting requirements.

Mounting is accomplished by providing a hole larger than the wheel diameter through the chamber wall. Wheel, shaft, motor, and drive assembly is then positioned to the inlet cone (mounted in opposite wall) and secured in place. See figure “A”.

Another method is to provide a hole sized only for the wheel drive shaft. Wheel is then positioned through the opening for the inlet cone after drive and panel assembly has been securely mounted. See figure “B”.

Plug fans may be applied with open wheel (unhoused) or with housing as shown in figure “C”. Catalog performance data in this catalog is for unhoused wheel application. Reference POWER FIXED BLOWERS Catalog, Non-Overloading POWER FIXED BLOWERS Catalog Supplement, and POWERFOIL BLOWERS Catalog, SWSI, for housed performance data.
