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. Volume (dBA) is measured 3 ft. from the air knife.
Air knives can be mounted with an adjustable arm or mounting bracket (sold separately). Knives up 6” wide can be supported with rigid pipe connected to your air supply.
Shim sets (sold separately) install in the airflow slot to adjust the flow and force of air.
