Product Details

Acting as a direct replacement for many OEM blowers with the same physical footprint, this dynamically balanced blower provides smooth and quiet operation. Noise and vibration are held to a minimum to maintain CFM at higher static pressures. The motor has cast-aluminum end shields for greater heat dissipation and protection, resulting in less downtime and longer service life. The min./max. operating temperature range is -20° to 104°F.

Customer Reviews

Rectangular Shaded Pole OEM Specialty Blower, Flange: Yes, Wheel Dia: 2-15/16 In , 115VAC is rated 4.5 out of 5 by 2.
Rated 4 out of 5 by from ONE OF THESE DIED EARLYWe've bought several as RF transmitter blower replacements. Long lasting, except for one...Despite the ball-bearings, one failed after a year and half, still working but making extremely loud grinding noise. The shaft was slipping on the rear ball bearing race, and had chewed a significant notch in the shaft surface (created caked black powder gunk.) The shaft was spinning but the ball bearing was not, creating extreme wear and bearing chatter noise. The ball bearing race was not stuck, instead the shaft was undersize, and spinning wo/touching the ball bearing race.This is the only blower that fits in our enclosure. On new replacements I remove the back bearing cover, remove the ball bearing race, and put a very tiny dab of RTV silicone caulk on the shaft surface. This should stop any wiggling/sliding of the shaft.Root cause probably is: shaft is undersize by 0.001" or less, so any slight imbalance of blower blades causes large vibration and slipping, slowly destroying the shaft.
