Pressure Air Fans
To meet specific applications, PA fans can be built with stainless steel or alloy construction. Split housings facilitate wheel removal without disturbing connecting ductwork. Integral inlet boxes, pre-spin inlet dampers and opposed-blade outlet dampers all control air flow. Belt guards and shaft coolers are also common options, in addition to the various housing and wheel liners. Chicago Blower engineers are eager to design and build the pressure fan that meets your exact requirements.
Application
Chicago's Pressure Air Fans are at work in as many diverse applications as they are in locations throughout the world. Clean air applications include combustion air, air drying primary air ejectors, and product cooling. This fan can handle pneumatic conveying systems. The PA fan is ideal for corrosive exhaust, air pollution systems and chemical processing. By adding ceramic tile or chromium carbide wheel and housing liners, Chicago's PA fans easily handle abrasive materials. In particular, fans with ceramic tile liners are extremely effective in pulverized coal applications, handling up to 250 grains per cubic feet of air. For corrosive gases, a stainless steel wheel and housing is available, or a lower cost rubber-lined, mild steel housing will often fulfill the requirements.
