Applications for Pressure Blowers include: combustion, air, fluid bed aeration, cooling, drying and many process system applications. It is also commonly used in pneumatic conveying systems.

It is also commonly used in pneumatic conveying systems. 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 / 9 S / 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.

SINGLE STAGE PRESSURE BLOWERS

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

Operating Range of Design High Pressure Blowers can be summarized as:

Maximum ...
... CFM: 18,000
Maximum Static Pressure: 91" wg
Maximum Temperature: 200°
Fan Sizes: 4" to 14"

DESIGN CAST ALUMINUM PRESSURE BLOWERS

Ventilating Fan Co. Design 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, Buffalo's pressure blowers are recommended for both electronic and food related applications. The non-sparking properties qualify Buffalo's pressure blowers for AMCA Type B spark resistant rating.

Operating Range of Design Cat Aluminum Pressure Blowers is:

Maximum CFM: 4,000
Maximum Static Pressure: 20" wg
Maximum Temperature: 200°
Fan Sizes: 8" to 18-1/2"

PA HIGH PRESSURE RADIAL FANS

To meet specific applications, Buffalo Fan PB 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 HPB High Pressure Radial Fans are:

Ventilating Fan Co. 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 HPB fan is ideal for corrosive exhaust, air pollution systems and chemical processing. By adding ceramic tile or chromium carbide wheel and housing liners, Buffalo'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 HPB Radial Blowers:

Maximum CFM: 440,000
Maximum Static Pressure: 108" wg
Maximum Temperature: 1000°
Fan Sizes: 20" to 100"
