SWSI, DWDI, AcF, PLR, BI, BC, AF, ST, Backward Inclined, Aerocline Fans, General Purpose Fans, GP, BL, Limit Load, LL, Buffalo Vent Set, BCV, BCA, BCM, BCS: industrial backward inclined blowers 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). Available in single width single inlet (SWSI), or double width double inlet (DWDI). Fan 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 fan wheel: industrial backward inclined (bi) blowers and fans are supplied with aluminum wheel or corten wheel to meet requirements of AMCA A, and AMCA B spark resistant blower construction. Mild steel wheels are of all welded construction. If higher pressure is required wheel can be furnished of high strenght steel. Stainless steel wheel in 304 SS, 316 SS, 316 SS, 2205 SS are supplied for corrosive applications, or high temeparature applications. The pressure curve remains stable 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 ventilator construction: shafting is straightened to close tolerance to minimize "run-out" and ensure smooth operation. Teflon fan shaft seal, ceramic 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.
Heat fan construction up to 800 F: includes high temperature paint, shaft cooler, shaft-cooler guard, and steel wheel, or alloy 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.
Ventilator 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 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, electrical / pneumatic actuators.
Controls and drives: variable frequency drives (VFD),
across-the-line starters, RTDs, pressure sensors, flowmeters - complete
