Duct Fans

Duct Fan (industrial duct blower fan)

Duct fan: axial flow through fan designed for low pressure building ventilation and industrial process application. Fan uses include heat, smoke, and fume removal; process ventilation and process air handling; proces drying with ambient or preheated up to 650 F air; comfort process cooling and general ventilation of buildngs. Available in direct drive arrangements 4/4M/4V/4D/4R and corresponding belt drive arrangements 9/9M/9V/9D/9R. Capacities: to 350,000 CFM. Static pressure to 1.5 inches water gauge.

Inlet flanges, outlet flanges, companion flanges: continuosly welded to match ANSI class 125/150, DIN, ISO, or custom hole pattern.

Fan shaft seals: shafting is straightened to close tolerance to minimize "run-out" and ensure smooth operation. Fan bearings are of pillow plock, or flaged bearings. Ceramic shaft seal and lubricated shaft seals (Buna, Teflon, Viton) are standard. Red silicone gasketing is used on high temperature ventilator applications.

Heat fan construction up to 650 F: includes high temperature paint, shaft cooler, shaft and bearing tunel cooling auxiliary blower (optional), insulated shaft and bearing tunel, steel, or alloy wheel.

Aluminum wheel, Steel wheel, or Alloy fan wheel: duct fan for non-sparking x-proof applications is supplied in AMCA A, AMCA B, or AMCA C spark resistant construction in all aluminum welded construction, or in monel. For corrosive environment duct fan is supplied in 304 SS, 316 SS, or 316 L stainless steel construction. For chemical process applications duct fan is available in fiber reinforced plastic frp construction, or in polypropylene construction, or in plastic. For high temperature applications up to 650 F duct fan is supplied typically in steel welded construction.

Cladding for sound attenuation and blower silencers: cladding consists of 2 inches mineral-wool insulation covered with a welded steel jacket. Acoustic cloth jackets are available as inexpensive alternative. Inlet silencers / outlet silencers are supplied with matching flanges.

Fan inlet vane damper assembly: external inlet vane damper is provided for precise air volume control.

Standard fan accessories:flash / raised access door, inspection port, drain and plug, 3-way drain, mount feet, belt guard, motor cover, spring vibration isolation, rubber-in-share (RIS) vibration isolation, vibrating pads, electrical actuators, pneumatic actuators.

Roof mount accessories: roof curb mount cap, roof curb, weather band, weather shroud with integral flap damper, butterfly damper assembly, magnetic latches.

Controls and drives: variable frequency drives (VFD), across-the-line starters, RTDs, pressure sensors, flowmeters - complete control packages.

Engineering sales of air knife blowers, blow off fans, stainless steel fans and SST blowers, spark resistant ventilators, combustion blowers, vane axial / tube axial blowers, high pressure ventilators, sealed blowers and fans, FRP fiberglass ventilators,
ventilators, propeller fans, exhaust silencers, air / gas exhaust systems. The potential of FRP composite for various applications is very wide. In view of the crucial need for developing indigenous
capability in composite technology the main advantage of FRP fans is their utilization and application of composite as an
important performance material in various sectors and to improve upon the laboratory-industry linkages towards development &
commercialisation. AB Blower Co. is a major supplier of plastic and fiberglass fans and blowers for industry applications where
aggressive media must be moved. Plastic fans include polypropelene, PVC, PVDF, fire retardant and UV resistant PPs. These
fans should also help to control air pressure within the building whether it be negative or positive pressure.
