Dayton AC Axial Fans ® Description Dayton AC axial fans are single speed units used for spot cooling where space is limited. They are widely used in computers, copy machines, electronic instrumentation, cabinet cooling, machine tool products, and solar systems. They are field interchangeable with most other axial fans, ball bearing units can be mounted in any discharge position while sleeve units can ONLY be mounted horizontally. Molded polycarbonate fan blade is driven by an impedance protected, shaded pole, unit bearing motor with a cast zinc Figure 1 venturi. Maximum ambient temperature is 158° F for sleeve bearing type and 176° F for ball bearing type. Model 4WT42A, 4WT43A, 4WT44A and 4WT45A have a PSC, thermally protected ball bearing motor. Optional finger guard and cordset (4WT40 and 4WT41 can not use a cordset) are available as accessories. Order separately.
