Stainless Steel Frame Electric Motors
Stainless-steel frame electric motors are engineered for the most demanding environments — from food and beverage plants to chemical, wastewater, and marine facilities where corrosion resistance and hygiene are mission-critical.
Constructed entirely from 304 or 316 stainless steel, these motors deliver superior protection against moisture, cleaning chemicals, and contamination, while maintaining NEMA-Premium efficiency and smooth, sanitary design for easy cleaning.
Crossman supplies washdown-duty and corrosion-resistant stainless motors across a full horsepower range, all meeting NEMA, CSA, and IP66/IP69K standards for durability and hygiene.
