What Is The Super Air Knife?
EXAIR’s Super Air Knife is the latest 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! Amplification ratios (entrained air to compressed air) of 40:1 are produced. The Super Air Knife meets OSHA dead-ended pressure and noise requirements.

Exair Air Amplifiers
Vent, exhaust, cool, dry, clean – with no moving parts!
What are Air Amplifiers?
A simple, low cost way to move air, smoke, fumes, and light materials. Air Amplifiers utilize the coanda effect, a basic principle of fluidics, to create air motion in their surroundings. Using a small amount of compressed air as their power source, Air Amplifiers pull in large volumes of surrounding air to produce high volume, high velocity outlet flows. Quiet, efficient Air Amplifiers will create output flows up to 25 times their consumption rate.

How Air Amplifiers Work
Compressed air flows through the air inlet (1) into an annular chamber (2). It is then throttled through a small ring nozzle (3) at high velocity. This primary air stream adheres to the coanda profile (4), which directs it toward the outlet. A low pressure area is created at the center (5), inducing a high volume flow of surrounding air in to the primary airstream. The combined flow of primary and surrounding air exhausts from the Air Amplifier in a high volume, high velocity flow.

What Are Air Nozzles and Jets?
A simple solution to excessive air consumption and noise levels on compressed air blowoff operations. Air Nozzles and Jets produce outlet flows up to 25 times compressed air consumption using a small amount of compressed air as the power source.
Why Air Nozzles and Jets?
Air savings, compared to open copper tubes or pipe nipples commonly used for blowoff can be as high as 80%. Less compressed air means less noise. The typical noise level reduction is 10 dBA. All EXAIR Air Nozzles and Jets meet OSHA maximum dead-ended pressure and sound level exposure requirements and are CE compliant.
An open 1/4″ (6mm) copper tube, by contrast, ejects pure compressed air at up to 40 standard cubic feet per minute (1133 SLPM), the entire output of a 10 horsepower compressor. Annual energy cost can exceed $1,000 per year (U.S. Dollars). Noise levels in excess of 100 dBA are commonly produced. When supply pressure exceeds 30 PSIG (2 BAR), an open jet violates OSHA static pressure requirements.
The Model 1213-12 Super Blast Safety Air Gun blows paper dust out of a web press with the airflow reaching deep into confined areas.
Reduce Noise Levels
High noise levels are a common problem for many plants. Compressed air noise often exceeds OSHA noise level exposure requirements, resulting in hearing loss to those working in close proximity. Noisy blowoffs at 80 PSIG (5.5 BAR) that produce noise levels of 100 dBA can be reduced to only 74 dBA when using a Super Air Nozzle. At that pressure, it is still possible to obtain hard-hitting force without the high noise.
Exair Static Eliminators
What are Static Eliminators?
A new technology solution to the old problem of static build-up. EXAIR Static Eliminators maximise ionised airflow while minimising compressed air consumption. A small amount of compressed air is used to entrain a high volume of surrounding air. This combined stream is ionised by an emitter point (or points) and delivered to the charged surface. Static is neutralised from distances up to 20 feet (6.1m) away. Thus, EXAIR Static Eliminators work effectively in spite of obstructions, three dimensional configurations, web “rippling”, etc.
Selecting the Right Static Eliminator
EXAIR offers systems for total static control. When static is a problem on moving webs, sheet stock, three dimensional parts, extrusions or packaging, EXAIR has a solution.
Static Eliminators with Air
Combining our engineered airflow products with ionizers gives us the ability to eliminate the charge quickly and at great distances. Laminar flow airstreams make it possible to blow away any contaminants and the charge that attracts them. They are ideal for:
- Hard to reach places or obstructed surfaces
- Product moving at high speeds
- Surfaces with an extremely high charge
Compressed air consumption and noise are minimised while providing force that can be adjusted from a “blast” to a “breeze”. Tests show these ionizers positioned two feet (610mm) away from a charged surface to be as effective as an Ionizing Bar without air delivery positioned one-half inch (13mm) from the surface.
Six of the Best
The Super Ion Air Knife provides the best performance of all ionizers. It uses our Super Air Knife (40:1 air amplification) to deliver a uniform sheet of ionised air effective up to 20 feet (6.1m) away.
The Standard Ion Air Knife uses our Standard Air Knife (30:1 air amplification) to deliver a sheet of ionised air to the surface. Air consumption and noise are somewhat higher than the Super Ion Air Knife.
The Ion Air Cannon uses our Super Air Amplifier (22:1 air amplification) to provide a focused, conical airstream that is capable of removing the charge up to 15 feet (4.6m) away.
The Super Ion Air Wipe uses our Super Air Wipe to provide a uniform 360° ionised airstream that is easy to clamp around a part for eliminating static electricity and contaminants.
The Ion Air Jet uses our High Velocity Air Jet (5:1 air amplification) to provide a narrow beam of ionised airflow. This hand-held static eliminator is rugged for industrial use and has incredibly fast static decay rates.
The Ion Air Gun is an effective spot cleaner. Available for permanent mount or with flexible Stay Set Hose, this ionizer is the ideal way to focus an ionised airflow at confined areas.
Static Eliminators Without Air
In some situations, even the smallest amount of airflow can disturb the product. This is especially true for lightweight materials. EXAIR manufactures two styles of ionizer for these critical applications.
Ionizing Bars are ideal for relatively flat materials, where the bar can be mounted within a few inches of the product surface.
The Ionizing Point is effective for spot neutralisation. The compact size makes it ideal for winding or slitting operations. It can also be mounted through a duct to neutralise static charges due to moving air or materials.
