Application:
Use for systems that require air delivery at high static pressures, such as garage carbon monoxide exhaust systems, electronic cooling or industrial applications.
Features:
General Construction
Housings and bases are 16 gauge steel with continuous arc-welded joints. Wheels are dynamically balanced and equipped with cast iron hubs. Blowers are finished with baked enamel.
Motors:
Single phase motors are 115/230 volt, capacitor start induction run type. Three phase motors are 230/460 volt, 60 cycle, squirrel cage induction run type. Standard units are furnished with open, continuous duty, ball bearing solid foot motors. Special motors are available such as totally enclosed, 25 or 50 cycle, explosion proof, etc.
