Design 38 Cast Aluminum Pressure Blower / Chicago Blower
Design 38 Cast Aluminum Pressure Blower : industrial pressure blowers and high pressure blowers supplied in cast aluminum, cast iron, or all-welded construction to prevent flexing at high pressure. Available in direct drive arrangements 4/4V/4H/7/8 and belt drive arrangements 1/2/9/10. Capacities: to 10,000 CFM. Single stage pressure blowers develop up to 4 psi static pressure. Two stage pressure blowers and multistage pressure blowers are for higher pressure.
Aluminum wheel, Steel wheel, or Alloy wheel: industrial pressure blower and high pressure blower wheels are of riveted, cast, or all welded construction. Flat wheel, tapered wheel, and dual tapered wheel design. Available with RBO radial self-cleaning blades; RTS radial tip blades; BI backward inclined blades, or BC backward curved non-overloading blades. Alloy wheels are available in SS 316L, SS 304, SS 204, monel, corten, FRP, and abrasion resistant construction. The pressure curve remains stable from wide open to closed off position without pulsation on all wheel designs.
Inlet flanges, outlet flanges, companion flanges: continuosly welded to match ANSI class 125/150, DIN, ISO, or custom hole pattern.
Shaft seals, low leakage, zero leakage, gas tight, airtight construction: shafting is straightened to close tolerance to minimize "run-out" and ensure smooth operation. Ceramic shaft seal and lubricated shaft seals (Buna, Teflon, Viton) are standard. Red silicone gasketing, gas-purgeable, double carbon ring shaft seal, gas-tight, or airtight construction, and zero-leakage construction.
Heat fan construction up to 700 F: includes high temperature paint, shaft cooler, shaft-cooler guard, steel, or alloy wheel.
Cladding for sound attenuation and silencers: cladding consists of 2 inches mineral-wool insulation covered with a welded steel jacket. Acoustic cloth jackets. Inlet silencers/outlet silencers supplied with matching flanges, or inlet/outlet venturi with guard, or plain pipe connection.
Inlet filter assemblies: cartridge type, with polyester element / wire mesh oil wetted element / high flow synthetic element / paper element. Available with protective hood, or hood-silencer.
Standard 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, wafer style / lug style outlet damper and electrical / pneumatic actuators.
Controls and drives: variable frequency drives (VFD), across-the-line starters, RTDs, pressure sensors, flowmeters - complete control packages in NEMA 1, NEMA 3R, NEMA 4 enclosure.
