Chicago Blower Pressure Blowers

Submitted by: Oleg Cthetchel

Chicago Blower CBC industrial pressure blowers and high pressure radial fans are 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 1/9S/9T/9H. 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.


An extremely wide performance range is provided by 70 wheel/housing combinations. The Design 53 is available in four arrangements and eight discharge positions to suit most every application. In addition to direct drive, the Design 53 is also available in belt drive.

Applications for High Pressure Blowers include:

Chicago Blower Design 53 single stage pressure blower is designed for combustion, air, fluid bed aeration, cooling, drying and many process system applications. It is also commonly used in pneumatic conveying systems.

Operating Range \ of Design 53 Pressure Blowers can be summarized as:

Maximum CFM: 18,000

Maximum Static Pressure: 91″ wg

Maximum Temperature: 200


Fan Sizes: 4″ to 14″


Chicago Blower Design 38 aluminum pressure blowers utilize high-strength alloys to create strong, corrosion-free housings and wheels ideal for adverse industrial environments. Aluminum also stands up to sub-zero ambients without material deterioration. Since aluminum is non-magnetic and non-toxic, Chicago’s pressure blowers are recommended for both electronic and food related applications. The non-sparking properties qualify Chicago’s pressure blowers for AMCA Type B spark resistant rating.

Operating Range of Design 38 Pressure Blowers is:

Maximum CFM: 4,000

Maximum Static Pressure: 20″ wg

Maximum Temperature: 200

Fan Sizes: 8″ to 18-1/2″


To meet specific applications, Chicago Blower CBC PA radial 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 for CNC PA High Pressure Radial Fans are:

Chicago Blower 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.

Operating Range for PA Radial Blowers:

Maximum CFM: 440,000

Maximum Static Pressure: 108″ wg

Maximum Temperature: 1000

Fan Sizes: 20″ to 100″
