SWSI, DWDI, AcF, PLR, BI, BC, AF, ST, Backward Inclined, Aerocline Ventilators, General Purpose Fans, GP, BL, Limit Load, LL, Buffalo Vent Set, BCV, BCA, BCM, BCS blowers: industrial backward curved blowers are supplied in welded heavy gauge steel construction to prevent flexing at high pressure. Available in direct drive blower arrangements 4/4V/4H/7/8 and belt drive arrangements 1/3/9/10. Arr. 10 blowers are known as ventilating sets (fan vent sets). Available in single width single inlet fan (SWSI), or double width double inlet fan (DWDI). Blower 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 fan wheel, Steel wheel, or Alloy fan wheel: industrial backward curved (bc) blowers and fans are supplied with aluminum wheel or corten wheel to meet requirements of AMCA A, and AMCA B spark resistant construction. Mild steel blower 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 fan 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.
Fan shaft seal and low leakage construction: shafting is straightened to close tolerance to minimize "run-out" and ensure smooth operation. Teflon 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. 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 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.
Fan 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 blower 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.

The main types of Axial Flow Fans include High-Temperature Axial Fans – High-volume fans designed to operate against low flow resistance in industrial convection furnaces. These are found in either single-direction or bi-directional designs. Extremely rugged, they are most often used in high-temperature furnace (up to 1800 degF) applications. A high pressure in-line fan developed by American Blowers Co. is Mix Flow Fan. Mixed Flow fans are an excellent choice for return air, supply, or general ventilation applications where low sound is critical. As compared to similarly sized tubular centrifugals and vane axials, a mixed flow fan will be 5-20 dB quieter! In addition, the mixed flow wheel is extremely efficient and will cut down on operating expenses.
