Chicago Blower Canada - Radial Fans, Blowers and Ventilators

Industrial Radial Blowers

Chicago Blower Radial Fans (industrial radial blade blowers) are supplied in welded heavy gauge steel construction to prevent flexing at high pressure. Available in direct drive fan arrangements 4/4V/4H/7/8 and belt drive ventilator arrangements 1/3/9/9S/9T.9H. Available in single width single inlet (SWSI) fan, 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 wheels are available: industrial radial 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. They are used on pressure applications, material handling applications (plastic scrap, paper trim, granular material, low density bulk material) where wheel is reinforced with support gussets, or made of abraision resistant construction, or furnished of high strenght steel. Stainless steel fan wheel in 304 SS, 316 SS, 316 SS, 2205 SS are supplied for corrosive applications, or high temeparature blower applications. The fan pressure curve remains stable from fully open to fully closed position.

Heat fan construction up to 1500 F: includes high temperature paint (up to 1000 F), special alloy construction, shaft cooler, shaft-cooler guard, and steel wheel, or alloy wheel, with steel, or alloy housing.

Shaft seal and low leakage fan construction can be furnished: 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.

Cladding for sound attenuation and silencers can be provided: 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.

Standard fan 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.

CONSTRUCTION FEATURES
• Cast aluminum wheel – airfoil blades provide highly efficient, quiet operation for clean-air applications.
• Heavy-gauge welded components – provide structural strength, durability, and minimal leakage.
• Bearings – selected to provide long service life... 50,000 hours average minimum  L-10. External lubrication fittings are standard.
• Industrial finish – green industrial grade coating.
• Straightening vanes – aerodynamically designed vanes convert velocity pressure to static pressure for maximum efficiency.
• Flanged connections – Welded flanges with slotted holes.
• Lubrication – extended lubrication lines with external fittings provided on all belt-drive Vaneaxial Fixed Pitch Fans.
• Adjustable motor mount – positive screw adjustment for easy belt-tensioning.
• Shafting – straightened to close tolerance to minimize “run out” and ensure smooth operation.
• Balance –  all  wheels are precision-balanced prior to assembly. Fans with mounted motors and drives are checked at the specified running speed.
• Inner-tube construction – isolates bearings and drive from airstream. Removable end cover allows access to bearings and drive.
• Tapered hub with split taper bushing – for ease in wheel removal.
