Air Knives deliver a flat sheet of amplified air designed to:

  • Efficiently blow off water and debris from wide surfaces
  • Provide high speed drying or cooling
  • Kill static, with an added static neutralizing bar on the Ionizing Air Knife.

Air Knives are air amplifiers, using a small amount of filtered compressed air to deliver a powerful, high velocity, laminar sheet of air over wide areas such as moving webs, film, sheets, strips, auto bodies and other large assemblies and objects. Vortec’s patented design produces increased thrust and velocity, reduced noise and excellent uniformity.


These knives add a static neutralizing bar, to discharge static to clean surfaces of dust, shavings and debris more effectively. The static neutralizing bar generates positive and negative charged ions that are carried to the target in a uniform sheet of amplified air. Ionizing Air Knives kill the static build up that can attract dust and contaminants that ruin a painted or coated surface; and stop static discharges which can damage electronic equipment and shock personnel.
