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
They are used on pressure applications, material handling applications
(plastic scrap, paper trim, granular material, low density bulk
where wheel is reinforced with support gussets, or made of abraision
construction, or furnished of high strenght steel. Stainless steel
in 304 SS, 316 SS, 316 SS, 2205 SS are supplied for corrosive
or high temeparature blower applications. The fan pressure curve
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
can be furnished: shafting is straightened to close tolerance to
minimize "run-out" and ensure smooth operation. Teflon shaft seal,
seal and lubricated shaft seals (Buna, Teflon, Viton) are standard. Red
silicone gasketing is provided for low leakage construction and for
temperature construction. Heavy-duty spherical roller bearings are
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.

Though the fan manufactures design fans on the basis of different needs, but some of the design parts are common. Ducted fans usually have an odd number of blades to prevent resonance in the duct. In the design of these fans, temperature is another factor where they have to be built and used. Due to more and shorter blades, aircraft fans operate at higher rotational speed. Advantages of duct fans this fan operates more efficiently at higher air speeds make them special. Through the fan, its designer can adjust the air velocity. Some other advantages are that ducted fans do not make much noise, allows a limited amount of thrust vectoring and offer enhanced safety on the ground. Emergency Duty Purge Up-Blast Ventilators incorporate elements of sealed and high-temp. consturuction for emergency fume and smoke exhaust.
