BAC CAUTION TIP:

What does IP mean? IP is an ingress protection rating that states the level of protection from solids and liquids for your motor.

The higher the number after the IP identifier, the higher the protection from potential water damage. If your motor is lower

than an IP55 rating, you are purchasing a motor that was not properly protected from water seeping into the motor and your

motor may prematurely fail in evaporative cooling equipment applications.
