MORE RUGGED: The 14 gauge steel housing with the baked on powder coating is more heavy duty than most blowers in this size range. Will take more wear in abrasive material handling applications.
SPARK RESISTANT: Model "SPB" Blowers with standard aluminum wheels and the addition of an aluminum rubbing ring are AMCA Type B spark resistant. (If you need AMCA Type A spark resistance, see Model "PB" Pressure Blowers.) Less expensive than the competition.
EASY PIPE OR DUCT CONNECTIONS: Model "SPB" Blowers have round inlets and discharges, so connection to duct or pipe is easily made with slip connections or flanges. Also allows for easy flexible hose connections. Does not require special square-to-round transitions.
AESTHETICALLY ATTRACTIVE: The appearance of the stamped steel "SPB" housing is a plus for industrial equipment designers that place value on a rugged yet smooth design. Very appealing to OEM designers.
