Air Cleaning Blowers Keep TEFC Motors Clean—and can do the same for open motors, too!
Totally Enclosed Fan-Cooled (TEFC) motors, as the name implies, have fans built into them to blow air along the motors’ sides to cool them.
These fans use the air surrounding the motors. If that air is dirty, the fans often cover the motors with the dirt. As the dirt builds up on the motors’ cooling fins, the transfer of heat diminishes, sometimes to the point of allowing the motor to overheat and be damaged.
However, now there is a way to minimize, or even eliminate, that accumulation of dirt with virtually no maintenance required:
Air Cleaning Blowers™ (ACBs) can replace those old-fashioned, built-in fans with ACBs that clean the cooling air without filter media and then blow the cleaned air around the motors.
In fact, ACBs can even go one step further and blow clean air THROUGH motors, open or enclosed, to cool the windings directly and improve the cooling even more.
