The AM Food Grade shaft seal eliminates product loss on food industry equipment.

The Inpro/Seal AM Food Grade is a permanent Air Mizer shaft seal design constructed of FDA approved material for product applications within food processing industries. Designed to last the lifetime of your equipment, the unique design of the AM Food Grade shaft seal is maintenance free with no wearing parts. The patented throttle/stator interface fully articulates to accommodate radial run-out, axial movement and angular misalignment simultaneously.

Features and Benefits

  • FDA Materials – allows for use in food industries
  • Internal Chamber – pressurizes sealing medium and directs it to the throttle
  • Opti-Mizer Throttle – pressurizes and efficiently distributes the sealing medium evenly around the circumference of the shaft, creating a positive purge
  • Throttle/Stator Interface – fully articulates to accommodate radial run-out, axial movement and angular misalignment simultaneously
  • Optional Designs/Features:
    • USDA – constructed of 3A certified materials and designed to meet USDA construction standards for use in meat, milk and dairy industries
    • DS – unique design for applications with a tight clearance between multiple shafts
    • ATEX – ATEX certified design for use in explosive environments like sugar and flour

Air Mizer Shaft Seal Upgrade Stops Costs and Product Loss from Piling Up

For a mixer that processes 15,000 lbs. of dry mix every hour, a leaking seal that requires replacement every six months is costly. Multiply these losses by 10 mixers, each operating three shifts a day, five days a week, and the accumulated losses become unsustainable. At a food manufacturing facility in Toledo, Ohio, leaking mixers were losing 830 lbs. of pancake mix every week. Read how a split AM Food Grade design has saved the plant $18,750 per mixer each year.
