    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


    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.

    • Dries surfaces quickly and thoroughly
    • Costs significantly less than fans or blowers
    • Inherently safe, with no guards or rotating equipment
    • Reduced compressed air usage, versus open nozzles
