• The first U.S.D.A. accepted air chain hoist in the United States.
• U.S.D.A. acceptance for meat and poultry equipment as listed in the FSIS Directive 11220.1.
• Corrosion resistance material - metal parts are either 300 series stainless steel, electroless nickel treated or Nickel Composite finished.
• Electroless nickel is a high-heat chemical treatment applied to aluminum components and provides high wear durability and will not flake off like paint.
  300 series stainless steel is highly corrosion resistant and is used for load hooks, bottom blocks and load chain for models with these stainless steel options.
  
• Nickel composite is a FDA approved proprietary finish used on ferrous metals to proved superior resistance to corrosion.
• A combination of stainless steel or electroless nickel hooks, hook blocks, and chain provides spark and corrosion resistance with the lifting parts for your "clean environment" application.
• The gear motor requires no air supply lubrication, therefore exhaust air is as clean and dry as the air supplied.
• Double protected - gear case is sealed and uses U.S.D.A. H-1 type grease.
• All bearings are permanently lubricated and sealed on both sides for U.S.D.A. acceptance.
• Washable and steam cleanable.
• No flaking of paint chips. Nonmetal parts are unpainted to prevent contamination.

Palair Premium - goes beyond U.S.D.A. requirements.

• Lubri-Link Green - Ingersoll-Rands exclusive U.S.D.A. accepted food grade chain lubricant provides the load chain with the recommended protection it needs.
• Trolley hoist applications - Nickel Composite plain hook-on PT-NC series trolley provides the same level of corrosion resistance protection as the hoist.
• Stainless steel piped away exhaust kit allows the exhaust to be piped away from the application.
• Abrasion, and oil resistant bright yellow pendent hose is highly visible, approved for food contact and easy to clean.
