Air Knives

Why Settle for Less Than The Best!


Nozzles
Air knives are the most efficient and energy saving method to deliver compressed air for large drying, cooling or cleaning applications. An air knife creates huge volumes of air with lower compressed air costs, by entraining surrounding air. Three models of air knives deliver air at 25:1 to 50 times the amount of compressed air used to help with your application needs.

    Textiles





    The Model 86036 Hurricane Air Knives are ideal for cleaning and drying large rolls of cloth.

    Painting





    The 36" Model 82036 Slim Line Air Knife with air filter creates an air barrier and helps prevent airborne powder from reaching the worker. The Slim Line construction ensures easy clean-up and long life.

    Frequently Asked Questions

    How do I mount the Air Knife?

    A rigid air pipe is the best way to mount the Air Knife. There is a very large air flow created and the rigid air pipe will hold the Air Knife as well as allow you to direct the air flow in the direction needed for your application.

    When should I supply compressed air to both ends?

    As a general rule, a 24" Air Knife and longer should be piped with compressed air coming in from both sides. This eliminates strong or weak spots in the overall length of the Air Knife.
