Roof Mounted Fans

Fan and ventilator products for commercial, institutional and industrial roof installations.

Select from a wide range of fan and ventilator products for commercial, institutional and industrial roof installations. There are products for exhaust, supply, recirculate, filtered, process and gravity applications. These products use two styles of fans — direct drive, used where maintenance access is difficult, or belt drive, which allows adjustment of fan speed for system balancing.


CENTRIFUGAL DOWNBLAST EXHAUST FANS

Roof-mounted centrifugal downblast exhaust fans include direct- and belt-driven fans. These models have backward-inclined centrifugal wheels. These fans are suitable for applications exhausting relatively clean air.


MIXED FLOW UPBLAST EXHAUST FANS

Mixed flow upblast fans are best in ventilation applications requiring low sound and high efficiency. Roof-mounted models discharge clean air or fume exhaust up and away from the building.

CENTRIFUGAL UPBLAST EXHAUST FANS

The centrifugal roof-mounted upblast exhaust fans include both direct and belt drive options with efficient backward-inclined centrifugal wheels and aerodynamic inlet cone minimizing system effects. The motors on the fans are out of the airstream. These fans are suitable for applications ranging from a storage room to fume hood exhaust and kitchen grease exhaust to smoke control.

AXIAL UPBLAST EXHAUST FANS

Axial fans are a cost-effective option for low to medium pressure applications. Roof-mounted models are designed to discharge clean air or fume exhaust up and away from the building. Typical uses are industrial space, warehouses, fume exhaust, and paint booth exhaust. Models are available in spark resistance construction, emergency smoke or continuous high-temperature exhaust. Select from direct and belt drive fans with cast aluminum or fabricated steel blades based upon application requirements.

CENTRIFUGAL SUPPLY FANS

Centrifugal roof supply fans include filtered and non-filtered belt-driven units. These fans are suitable for non-tempered kitchen make-up air or building supply air.

HOODED AXIAL EXHAUST FANS

Hooded propeller roof exhaust fans include both direct- and belt-driven fans. These fans are suitable for exhausting in clean air applications including factories and warehouses.

HOODED AXIAL SUPPLY FANS

Hooded propeller roof supply fans include both direct- and belt-driven styles. These fans are suitable for supplying air in clean air applications including factories and warehouses.

HOODED AXIAL REVERSIBLE FANS

Hooded propeller reversible roof fans include both direct- and belt-driven fans designed to move air in both exhaust and supply modes for clean air applications. Typical applications are factories and warehouses.

AXIAL RECIRCULATING FANS

These roof-mounted, direct drive, recirculating fans come with and without filters. Each unit has the ability to exhaust or supply air on demand. Available with optional control centers, fans are suitable for clean air applications, such as factories and warehouses.
