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 coat the motors with the particles, sometimes blowing rain on them that can help the sand and other contaminants stick or corrode the motors. 

 As the layers of grime builds up on the motors’ cooling fins, the transfer of heat diminishes, sometimes to the point of causing the motor to overheat and become damaged.

However, now there is a way to minimize, or even eliminate, that build-up of grit and corrosion with virtually no maintenance required:

Air Cleaning Blowers, LLC can replace those old-fashioned, built-in fans with ACB Impeller Adaptors.  These Adaptors replace the impellers made by the manufacturer of the motor with specially designed and patented Air Cleaning Blowers™ (ACBs) that clean the cooling air without filter media and then blow the cleaned air around the motors. ACB Impeller Adaptors can even go one step further and blow clean air THROUGH motors to cool the windings directly and improve the cooling even more.  In the process, they will help open and drip-proof motors last longer and to operate more reliably.
