Industrial Ventilation Fans and Blowers

Duct Centrifugal Fans

Size: 10.5" - 49"

CFM: Up to 67,407

The Centrifugal Duct fan represents the latest development in the fans and blowers industry. Incorporating the tried and proven, highly efficient wheel in a vane-equipped tube the Centrifugal duct thus offers the combination of superior performance comparable to scroll type centrifugal fans and minimum space requirements formerly associated only with axial fan types.

In addition to the obvious space saving advantages of the tubular design, the need for duct turns and transition pieces is eliminated, thus providing simpler and less costly installation. Inlet and outlet diameters are identical and floor, wall or ceiling installation for vertical or horizontal airflow can be made with equal ease.

Plug/Plenum Fans

Size: 15"- 49"

Plenum Fans are designed to operate inside field erected or factory built air handling units. The fan pressurizes the air plenum in which the fan operates. This allows air ducts in any direction to be directly connected to the air handling unit enclosure. The design saves space by eliminating the fan housing and ductwork transition to the plenum.  Plenum fans have established industry standards for design, performance and reliability.

Centrifugal Fans

Model: SWSI & DWDI
Size: 10.5"- 49" (SWSI); 12.25"- 24.25" (DWDI)

Centrifugal nonoverloading blower is built for the many applications required by both commercial and industrial users. The backward inclined flat blade construction produces a high efficiency blower ideal for medium and high pressure applications. This highly efficient design provides for extremely quiet operation.

Each blower housing is continuously welded for sturdy construction. Only rugged duty cast iron housed bearings are installed in the "Power Fixed" blower. Shafts of nonsulpharized carbon steel are precisely turned, ground and polished for a precision fit. Each wheel is statically and dynamically balanced for optimum trouble-free performance and longevity. The "Power Fixed" non-overloading blower is built with dependability and minimum maintenance in mind.
