The benefits you will receive from Cincinnati Fan Model "PB" Cast Aluminum Pressure Blowers are:

SPARK RESISTANT: Model "PB" Pressure Blowers are AMCA Type B spark resistant. With the addition of an aluminum shaft collar and brass hardware, they will meet AMCA Type A spark resistant requirements. Standard feature much less expensive than the competition.

EASY PIPE OR DUCT CONNECTIONS: All Model "PB" Pressure Blowers have round inlets and discharges, so connection to pipe or duct is easily made with slip connections or flanges. Does not require special square-to-round transitions.

ATTRACTIVE: Cast aluminums natural appearance adds to the esthetics of the equipment it is mounted on. Provides a rugged appearance and it can be brushed, buffed, or colored by anodizing. It also has excellent paint adhesion. Superior esthetics for OEM designers at no extra cost.

CORROSION FREE: No painting is required for a maintenance free moist environment. Will not rust.

NON-TOXIC: Aluminum is "friendly" to foods, beverages and medicines. Model "PB" Pressure Blowers are used in many food processing applications where cleanliness is critical and equipment wash downs are a daily occurrence. Less expensive than stainless steel.

NON-MAGNETIC: Cast aluminum resists magnetism even in magnetic fields making it ideal in electronic applications where preventing interference is extremely important. No magnetic isolation required.

NOT AFFECTED BY COLD: Unlike many materials that become brittle when super cold, aluminum alloys actually become stronger. That makes Model "PB" Pressure Blowers ideal for temperatures below 0° F. Can be installed out doors.

STRONG: Aluminum’s strength is exhibited in products such as guard rails, truck trailers and baseball bats. In high speed blower wheels, aluminum is alloyed with magnesium, titanium or other alloys for even greater strength. Provides very long service life in demanding applications.

WORKABLE: Aluminum can be machined by almost every metal working process. Makes future modifications easier.
