Super Air Knife - quiet, hard-hitting curtain of air for blowoff, cleaning, drying and cooling

Supplier: Compressed Air Australia

EXAIR's Super Air Knife is a new generation of air knife that dramatically reduces compressed air usage and noise when compared to other blowoffs. The 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.


Noisy blowoffs become a whisper when replaced with the compact Super Air Knife.  Even at high pressures of 80 PSIG (5.5 BAR), the sound level is surprisingly quiet at 69 dBA for most applications!  Air amplification ratios (entrained air to compressed air) of 40:1 are produced.  Meets OSHA maximum dead-ended pressure and noise requirements.


The laminar airflow of the Super Air Knife is perfect for removing moisture prior to packaging, painting, labelling, bar coding and assembly.  Common applications include drying parts, rolled steel, circuit boards, webs, bottles, cans and more.  Velocity is easily adjusted from a "blast" to a "breeze" with a pressure regulator.


The Super Air Knife is ideal for blowing off chips, dirt or water from parts, webs or conveyors.  It delivers a uniform sheet of air that has the same force across the entire length.  There are no interruptions or "dead spots" which mean all surfaces are dried or cleaned.  The Super Air Knife is available in aluminium or stainless steel for corrosive and high temperature applications.


Great volumes of airflow can be generated in very tight spaces due to the compact size of the Super Air Knife.  Flow and force are easily controlled with a pressure regulator, allowing fast or gradual cooling.  Shims can be installed if additional hard-hitting velocity is required.

Open, Float, Separate

The uniform airflow exits the Super Air Knife in a perfectly straight line (does not deflect).  It is ideal for opening bags and pouches, floating webs, and keeping environments separate.

Applications of Super Air Knife:

Part drying after wash

Sheet cleaning in strip mills

Conveyor cleaning

Part or component cooling

Web drying or cleaning

Environmental separation

Pre-paint blowoff
