Industrial Aerofoil Fans and Blowers

SWSI, DWDI, AcF, PLR, BI, BC, AF, ST, Backward Inclined Fans, Aerocline, General Purpose, GP, BL, Limit Load, LL, Buffalo Vent Set, BCV, BCA, BCM, BCS fans: industrial aerofoil fan blowers are supplied in welded heavy gauge steel construction to prevent flexing at high pressure. Available in direct drive arrangements 4/4V/4H/7/8 and belt drive arrangements 1/3/9/10. Arr. 10 blowers are known as ventilating sets (vent sets). Fans are available in single width single inlet (SWSI), or double width double inlet (DWDI). Capacities: to 500,000 CFM. Static pressure up to 100 inches water gauge depending on the class of construction. Typical class of construction is Class 1, 2, 3, 4, 5.

Aluminum wheel, Steel wheel, or Alloy ventilator wheel: industrial aerfoil (af) blowers and fans are supplied with aluminum wheel or corten wheel to meet requirements of AMCA A, and AMCA B spark resistant ventilator construction. Mild steel fan wheels are of all welded construction. If higher pressure is required wheel can be furnished of high strenght steel. Stainless steel ventilator wheel in 304 SS, 316 SS, 316 SS, 2205 SS are supplied for corrosive applications, or high temeparature blower applications. The blower pressure curve remains stable at the top are of the fan curve and to the right of the pick point.

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

Shaft seal and low leakage blower construction: shafting is straightened to close tolerance to minimize "run-out" and ensure smooth operation. Teflon shaft seal, ceramic fan shaft seal and lubricated shaft seals (Buna, Teflon, Viton) are standard. Red silicone gasketing is provided for low leakage construction and for high temperature construction. Heavy-duty spherical roller bearings are standard.

Heat fan construction up to 800 F: includes high temperature paint, shaft cooler, shaft-cooler guard, and steel wheel, or alloy fan wheel.

Cladding for sound attenuation and silencers: cladding consists of 2 inches mineral-wool insulation covered with a welded steel jacket. As an inexpensive alternative is offered slide-on acoustic cloth jackets. Inlet silencer/outlet silencer are supplied with matching flanges for further attenuation of the noise level.

Blower inlet filter assemblies: cell type, 1 inch, or 2 inch filters are available with filter cabinet to be mounted at fan inlet. Bird guard, insect screen and weather hood are optional accessories with inlet filter package.

Standard fan accessories:flash / raised access door, inspection port, drain and plug, unitary base, shaft and bearing guard, belt guard, motor cover, spring vibration isolation, rubber-in-share (RIS) vibration isolation, vibrating pads, outlet damper, inlet vane damper, external inlet vane damper, evase, electrical / pneumatic actuators.

DIRECT DRIVE: Available in sizes from 7 inch to 60 inch, direct driven models require less maintenance, offer longer operating life, increased efficiency and reduced operating cost.

These fans can be arranged for supply, exhaust or a combination of 
both.


Wall Exhaust Fans are used for industrial ventilation, laundries, kitchen exhaust and farm buildings where large volumes of air are required or where fans must operate against resistance, and may also be installed in duct installations where low static resistance is encountered. Furthermore, Wall Mount Exhaust Fans as heavy duty industrial ventilating fans are presented in steel mills, machine shops, packing plants, etc. or in duct installations where static pressure up to one inch is encountered --- AMCA Certified.
Custom Features Special reverse flow fans for blowing air into buildings; inlet and discharge guards are optional features available for a slight additional charge. For installation in hazardous locations, fan units with explosion proof motors, non-ferrous blades and spark proof belts are available.
