Chicago Blower Canada Fans and Blowers

Industrial airfoil (AF) fans and blowers.

Supply air or clean exhaust application is ideal for Chicago Blower SQA airfoil fans. For dirty air or dusty air, the SQB fan version with backward inclined blades is recommended. The SQA blower is also suited for high temperature gases handling as well as for air conveying blower applications.
Chicago Blower tubeaxial fans, vaneaxials 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. Airfoil fans are available in single width single inlet fan (SWSI), or double width double inlet fan (DWDI). Capacities: to 500,000 CFM. Static pressure up to 50 inches water gauge depending on the class of construction. Typical fan class of construction is Class 1, 2, 3, 4 and 5.

Aluminum fan wheel, steel wheel, or FRP 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 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 SST are supplied for corrosive applications, or high temeparature applications. The 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 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 1800 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.

Inlet filter assemblies available: 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 include: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.
