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 arrangements 4/4V/4H/7/8 and belt drive arrangements 1/3/9/9S/9T.9H. Available in single width single inlet (SWSI), or double width double inlet (DWDI). 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
wheel
in 304 SS, 316 SS, 316 SS, 2205 SS are supplied for corrosive
applications,
or high temeparature applications. The 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 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 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.
