Washdown Motors
LEESON® Washguard® motors deliver something most washdown duty motors can’t — the confidence to know your applications will be up and running no matter what you throw at them. Whether you need a motor that handles an occasional splash or a solution that handles continuous washdown 24/7, Regal Rexnord’s broad range of LEESON washdown motors can take it.
Choose a solution that’s USDA approved, FDA approved, BISSC certified, or a motor with an IP69 rated enclosure protection — to name just a few. If you’re looking for answers to tough application issues, look to LEESON motors.

CHEMICAL RESISTANCE COMPARISON
Preventing rust and corrosion in washdown environments is a top priority in the food and beverage industries. Even a small trace of rust or corrosion is enough to shut down a line causing unwanted downtime and possibly resulting in regulatory fines. In order to prevent rust and corrosion, take time to review the washdown chemicals used in your facility and evaluate the motors exposure to washdown procedures. Choose a finish that supports the level of protection required for that application.
