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 are retracted back into the tractor. In this way, effluent is kept out of the equipment, preventing performance issues and increasing component life.


  • Removes contamination on hoses, improving hose traction and allowing the tractor to be run at lower clamp pressures
  • Offers great value for reducing operator cleaning time roller/belt wear in oily or slippery applications
  • Quick and simple to install, no wear items
