Super air knife
December 2005
Pneumatics & Hydraulics
Exair's Super Air Knife is a new generation of air knife that dramatically reduces compressed air usage and noise compared to that of other blow offs. 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.
In most applications previously noisy blow offs can become a comparative whisper (69 dBA) when replaced with a compact Super Air Knife - even at high pressures of 55 MPa. Air amplification ratios (entrained air to compressed air) of 40:1 are produced. The Super Air Knife meets OSHA maximum dead-ended pressure and noise requirements. Applications would include:
* Part drying after wash.
* Sheet cleaning in strip mills.
* Conveyor cleaning.
* Part or component cooling/drying.
* Web drying or cleaning.
* Environment separations.
* Pre-paint blow off.
* Bag opening/fill operations.
* Scrap removal on converting operations.
* Drying pre-printing.
Advantages include quiet operation (<69 dBA for most operations), minimal air consumption (40:1 air amplification), uniform air flow across entire length, variable force and flow, no moving parts - maintenance free, easy mounting - inlets on each end and bottom, compact, rugged, easy to install, stainless screws on all models and the units are available in special lengths.
