Clean, Dry or Cool Parts with EXAIR Super Air Knife from Compressed Air Australia

EXAIR Super Air Knife eliminates noisy blowoff and air flow is straight, strong and ideal for drying, cooling and cleaning


EXAIR Super Air Knives
deliver a uniform sheet of laminar airflow across the entire length with
hard-hitting force offering a more efficient way to clean, dry or cool parts,
webs or conveyors.

The best way to cut
energy costs is through proper maintenance and use of the compressed air
system. The most important factor to dramatically boost efficiency is
proper use. The Super Air Knife uses only 1/3 of the compressed air of
typical blowoffs
used in cleaning, cooling and drying operations and
can be instantly cycled on and off.

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. Air amplification ratios
(entrained air to compressed air) of 40:1 are produced. Meets OSHA maximum
dead-ended pressure and noise requirements and is CE compliant.

Reduce compressed air while drying, blowing off, cooling, opening, floating & separating

Dry – 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.

Blowoff – 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, PVDF or stainless steel for corrosive and high
temperature applications.

Cool – 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,
– 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.
