How the Super Air Knife Works

How the Super Air Knife Works

 

Super Air Knife

Super Air Knife

EXAIR's Super Air Knife offers a more efficient way to clean, dry or cool parts, webs or conveyors. It delivers a uniform sheet of laminar airflow across the entire length with hard-hitting force. Even at high pressures of 80 PSIG (5.5 BAR), the sound level of the Super Air Knife is surprisingly quiet at 69 dBA for most applications! Amplification ratios (entrained air to compressed air) of 40:1 are produced. The Super Air Knife is available in aluminum, stainless steel, and PVDF.

Standard Air Knife

EXAIR's Standard Air Knife offers a lower cost alternative to our Super Air Knife. Amplification ratios of 30:1 are achieved as well as a noise reduction of up to 10 dBA. Air savings of 40% to 90% are possible when replacing "homemade" blowoff devices. The Standard Air Knife is available in aluminum or stainless steel.

EXAIR's Full-Flow Air Knife utilizes the Coanda effect to pull in large volumes of surrounding air, producing a high flow, high velocity curtain of air across the entire length of the air knife, allowing it to operate effectively in tight-fitting areas. The Full-Flow Air Knife is available in aluminum and stainless steel.
