    High-Efficiency Air Knives

    Image of ProductInUse. Front orientation. Contains Annotated. Air Knives. High-Efficiency Air Knives.
    Producing the same airflow as standard air knives, these are quieter and use 18% less compressed air. Air knives create a sheet of high-velocity air for drying and cooling parts, wiping conveyor belts, controlling coating depth, and blowing liquids, chips, and dust from equipment. They conform to OSHA 29 CFR 1910.242 requirements for maximum air outlet pressure and OSHA 29 CFR 1910.95 requirements for noise.
    Air knives can be mounted with a positioning arm or mounting bracket (sold separately).
    3" Overall Width and 6" Overall Width—Knives up to 6” wide can be supported with rigid pipe connected to your air supply.
    Volume (Sound)—Volume (sound) is measured 3 ft. from the air knife.
    Air Knife Shim Sets—Air knife shim sets (sold separately) install in the airflow slot to adjust the flow and force of air.
