PRESSURE BLOWER

Model PB

Arrangement 9

Arrangement 4

Model PB Pressure Blowers

Pressure blowers provide medium pressure air for cooling, ventilating and exhaust systems handling dust, materials or corrosive fumes.

Wheel

Cast aluminum wheel furnished as standard. Suitable for air, light dust, and mild chemicals in acidic pH range. For resistance to more severe abrasion, chemicals and high temperatures, specify an aluminum-bronze "Dura" alloy wheel. Fabricated steel and stainless steel wheels are available upon request.

Features

· Direct drive or belt driventhrough 12" diameters · Wheelcapacities tofrom 8"CFM 1275 · Flow pressure to 10" w.g. Static · Temperature to 600°F (with modifications) ·

Accessories

Weather Cover and Belt Guard

The weather cover protects the motor, drives, and bearings from the elements. Available on Arr. 9 fans with fractional horsepower motors only. The belt guard is available for all belt driven arrangements and sizes. Complete mounting details are required for Arrangement 1 fans.

Shaft Seals (belt driven units only) Elastomeric rotary seal -- Rides against a heavy Teflon wear plate. A spare seal is provided as standard. This seal is suitable for operation up to 300°F.

Ceramic felt -- Elements are encased between housing drive side and metal retaining plate. Ceramic felt inserts may easily split for field installation and maintenance. This seal is best suited for 301°F to 600°F operation. These seals minimize leakage around shaft opening but are not gas tight.

Motor Cover

The motor cover protects the motor from the elements. Available on Arr. 4 fans only.

Heat Fan

Belt driven heat fan (Arr. 1 & 9) includes aluminumbronze "Dura" wheel and A240 aluminum two-piece heat slinger. Arrangement 9 includes a motor heat shield. Suitable for temperatures to 600°F. Direct drive heat fan (Arr. 8) -- Consult factory. Includes aluminum-bronze "Dura" wheel and A240 aluminum two-piece heat slinger. Suitable for temperatures to 600°F.

Drain

1" standard drain welded to housing at lowest point.

Flanged Inlet and Outlet

The flanged inlet is a circular plate welded flush with standard slip inlet. Holes are provided.

BC

The flanged outlet is welded flush to the outlet. Holes are provided for matching the duct flange.

Drive Arrangements

Arrangement 1

Versatile and rugged V-belt drive arrangement with the motor mounted separate from the fan base. Maximum temperature of standard fan is 300°F. Maximum temperature of heat fan is 600°F*. Specify AMCA motor position designation (see below) and fan RPM when ordering fan complete with drives and motor.

Arrangement 4

The most compact and least expensive direct drive arrangement with the wheel mounted directly on the motor shaft. Arrangement 4 fans are available in a limited number of models. Minimum motor frame size is 48 for the 8" and 56 for the 10" and 12". Maximum temperature of standard arrangement 4 fan is 180°F. For direct drive heat fans (Arrangement 8 only), please consult the factory.

Arrangement 9

Compact V-belt drive arrangement with the motor mounted on the fan support base. This arrangement will accept a full range of motor frame sizes through 184T. Maximum temperature of standard fan is 300°F. Maximum temperature of heat fan is 600°F*. Standard construction is with the motor on the right when facing the end of the shaft. Indicate motor and mounting description (right or left) when ordering.

* Heat fan includes an aluminum-bronze "Dura" alloy wheel, A240 aluminum two-piece heat slinger, and heat shield. The heat slinger protects against transfer of heat through the shaft to the bearings.

Motor Positions

The drawing at right illustrates the AMCA motor position standards for Arrangement 1 fans. The location of the motor is determined by facing the drive side of the fan and designating the motor position by letters W, X, Y, or Z.
