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 also handle pneumatic conveying systems. The Pressure Air 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 Pressure Air 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.
