Air Knife

The Air Knife is an accessory for AutoBox ABX-2L and ABX-3L tractors designed to improve hose traction in oily, greasy, or sticky applications. The Air Knife sits between the tube face and the AutoBox, blowing a continuous “blade” of pressurized air across the hoses before they retract back into the tractor. Keeps effluent out of the equipment, preventing performance issues and increasing component life.


  • Removes contamination on hoses, improves hose traction
  • Allows the tractor to be run at lower clamp pressures
  • Reduces operator cleaning time and roller/belt wear in oily or slippery applications
