Stainless Steel Tough for demanding washdown applications
Mechanical Protection Features:
All exterior components - frame, base, endshields, fan guard, shaft, hardware, conduit box and cover - are made from 300 series stainless steel for maximum corrosion resistance. Nameplate data is permanently laser-etched into the motor frame - no Mylar nameplate that can wash off or riveted metal nameplate to trap dirt. No paint or any type of coating is used on the exterior of the motor. Sealant is applied to endshield and frame fits before assembly to prevent water entry. Shaft seals on both ends of TEFC motors - shaft end only on TENV. Double-sealed bearings have high performance Exxon Polyrex EM grease. Conduit box is fully gasketed half-split design with flanged cover and body gasket with lead separator. Anticorrosion coating on rotor prevents corrosion. Four quadrant drain locations on each endbell allow drainage of condensation in any mounting position. Stainless steel T-drains are provided to prevent liquids from splashing into the drain locations. Motors are shipped with a T-drain assembled in the six o'clock position on the opposite endshield. Another T-drain is shipped loose in the conduit box for installation at the lowest point of the shaft-end endshield. For a totally sealed motor, a spare pipe plug is included to replace the pre-installed T-drain. Mechanical performance is further enhanced by over-sized bearings, heavy 12 gauge base, shaft-end bearing is locked internally to limit axial endplay, and specially designed shaft extension resists breakage at bearing journal.
Electrical Performance and Protection Features:
FHP Washguard SST full load efficiencies meet EPACT standards for non-exempt motors when tested without shaft seals. For extra moisture resistance, windings are immersed and cured in polyester insulating varnish. LEESON’s exclusive IRIS™ Inverter-Rated Insulation System provides extra protection and long life, especially in inverter driven applications. 20:1 Constant Torque Operation
Standards and Approvals:
UL component recognized, file number E57948, guide number PRGY2. Energy efficiency ratings are verified by an independent testing laboratory. CSA Energy Efficiency Verification Program, report number EEV 78720-1.
Construction is CSA Certified for safety report number LR33543. Motor is CE marked for European acceptance.

| Mechanical Features |
These motors have an entirely paint free exterior with 300 series stainless steel motor body, conduit box lid, shaft extension, hardware, fasteners and an etched motor data plate. To enhance chemical and corrosion resistance, all surfaces of the end bells and conduit box are processed using a U.S. Department of Agriculture approved technique. This proprietary process has been tested and qualified for more than 2,500 hours of salt spray endurance for external surfaces, and 1,000 hours for internal surfaces. This process has proven successful in food wash down applications and has shown excellent corrosion resistance. Shaft seals, slingers and one-way stainless steel drains retard entrance of contaminants and water into the motor. Multiple, repositional drains provided for all angle mounting, release any water that does enter the motor from hose downs or condensation. Chemically resistant, tough nitrile gaskets and a threaded entrance for power connection also restrict entrance to the motor’s interior. Nylon gaskets are used to seal bolt heads. Bearings used are double sealed and prelubricated with moisture resistant Exxon POLYREX® EM high temperature lubricant. |
