Innovative high-pressure blower assembly with squirrel-cage fan wheel

This high pressure blower assembly with squirrel-cage fan wheel was new for the late 1930s

This high pressure blower assembly with squirrel-cage fan wheel was new for the late 1930s. Its resilient-mounted electric fan motor, on the right side, with an adjustable, variable speed, motor pulley and “V” belt drive reduced vibration, making it more acceptable to a generation that was unaccustomed to whirring motors, belts, and pulleys.
