摘要： A bypass motor/fan assembly for use in applications where moisture laden air is encountered. A motor with a motor cooling fan has a fan end bracket received at one end thereof to isolate the motor and motor cooling fan from a working air fan received on the opposite side of the fan end bracket. A diffuser matingly engages with the fan end bracket. The diffuser and fan end bracket have ramped surfaces thereon which are circumferentially aligned with the working air fan. The ramped surfaces define air flow paths of uniform cross section which pass to exhaust ports which are circumferentially spaced about a fan shell which is received over the fan end brackets, diffuser and working air fan. The fan shell has an air intake aperture at an end thereof. Air passes from the air intake aperture, into the eye of the work air fan, and out of the fan at the circumference thereof into the air paths of uniform cross section and to the exhaust ports. This channeling and ducting of the working air achieves a laminar flow and reduces turbulence and pressure pulses, increasing the efficiency of the working air fan and reducing the noise incident to the operation thereof.
