AIR MOVEMENT
Moving air for indoor comfort, safety, health, and productivity as well as material handling.
Air movement products (fans and blowers) draw fresh, outdoor air into non-residential buildings; circulate air throughout; and exhaust stagnant, smoky, greasy, unpleasant, and contaminated air and fumes from a building. Blower products can move airborne light materials such as sawdust, wood chips, dust, and other fine particles.
Fans_Roof-Mounted
ROOF MOUNTED FANS
Roof curb mounted fan and ventilator products supply and exhaust applications for commercial, institutional and industrial installations.
Fans_Inline
INLINE FANS
Designed for inline installations and offering a wide performance range. Fans are used for clean air, sound sensitive, industrial or grease-laden exhaust air applications.
Fans_Jet
JET FANS
Ductless design uses transfer fans to dilute and remove contaminants and control smoke. These move air towards exhaust areas.
Fans_Wall-Mounted
WALL MOUNTED FANS
Includes both direct and belt drive axial propeller fans suitable for in wall mounted applications. 
Fans_Circulators
CIRCULATORS
Fans that improve working conditions. These fans recirculate air and cool workers in many industrial settings. 
Fans_Ceiling-Cabinet
CEILING EXHAUST FANS
Ceiling exhaust fans are ideal for clean air applications such as bathroom and general exhaust.
Fans_Blowers
BLOWERS
Low flow and high pressure air movement for removing hot air, moisture, fumes and small, lightweight particles such as dust, wood chips, and paper trimmings.
Fans_Laboratory-Exhaust
LABORATORY EXHAUST FANS
Fan systems designed and engineered to remove hazardous or noxious fumes meeting laboratory requirements. Exhaust effluents have high discharge velocities and plume height.
Fans_Fume-Exhaust
FUME EXHAUST FANS
Pre-engineered, centrifugal exhaust systems designed to safely remove and disperse contaminated air in commercial, institutional or industrial applications.
Fans_Plenum
PLENUM FANS
Compact and economical, plenum fans are designed to operate individually or as a multi-fan array in air handling and pressurized plenum applications.
Fans_Roof-Curbs
ROOF CURBS
Roof support structures for fans and ventilators on flat, pitched, or ridged roofs.
