Vaneaxial Fan (industrial vaneaxial blower fan)
Vaneaxial fan: axial flow through fan designed for medium and high pressure building ventilation, mining ventilation, industrial ventilation and industrial process application. 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 14 inches water gauge. Available in two stage configuration.
Aluminum wheel, Steel wheel, or Alloy wheel: vaneaxial 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 vaneaxial fan is supplied in 304 SS, 316 SS, or 316 L stainless steel construction. For chemical process applications vaneaxial fan is available in fiber reinforced plastic frp construction, or in polypropylene construction, or in plastic. For high temperature applications up to 650 F vaneaxial fan is supplied typically in steel welded construction.
Inlet flanges, outlet flanges, companion flanges: continuosly welded to match ANSI class 125/150, DIN, ISO, or custom hole pattern.
Shaft seals: vaneaxial shafting is straightened to close tolerance to minimize "run-out" and ensure smooth operation. 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 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.
Cladding for sound attenuation and 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.
Inlet vane damper assembly: external inlet vane damper is provided for precise air volume control.
Standard 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: all standard controls available.
