Super Ion Air Knife™

Powerful static eliminator prevents jamming,
tearing, shocks and dust up to 20 feet away!

	Low Air Consumption!
	Uniform Airflow!
	Surprisingly Quiet!
	End and Bottom Air Inlets!

What is the Super Ion Air Knife?

EXAIR's new Super Ion Air Knife removes static electricity from plastics, webs, sheet stock and other product surfaces where tearing, jamming or hazardous shocks are a problem. The laminar sheet of air sweeps surfaces clean of static, particles, dust and dirt. Production speeds, product quality and surface cleanliness can improve dramatically.

Materials stay in position on an "L" sealer when static electricity is neutralized.

Why the Super Ion Air Knife?

The Super Ion Air Knife floods an area or surface with static eliminating ions - up to 20 feet (6.1m) away. A balanced airflow across its length will not cause misalignments to critical surfaces such as webs. Force can be adjusted from a "blast" to a "breeze".

The Super Ion Air Knife is electrically powered, is shockless and has no moving parts. It also requires less than 2 SCFM of compressed air per foot of length at 5 PSIG (57 SLPM per 30cm of length at 0.3 BAR). Sound level is surprisingly quiet at 50 dBA for most applications.

Applications			Advantages
	Web cleaning			Low air consumption
	Molding machinery			Uniform airflow across entire length
	Sheeters and trimmers			Quiet
	Cleaning parts			Effective up to 20' (6.1m)
	Pre-paint dust removal			Shockless, non-radioactive
	Shrink wrappers			Compact, rugged, easy to install
	Package cleaning			Variable force and flow
	Printing equipment			Low maintenance
	Bag opening/fill operations			Unlimited system lengths of uninterrupted airflow

Bumpers, car bodies and fascia are cleaned of dust and fibers prior to painting.

How the Super Ion Air Knife Works
Compressed air flows through an inlet (1) into the plenum chamber of the Super Ion Air Knife. Multiple channels inside direct the flow to a precise, slotted orifice. As the primary airflow exits, it creates a balanced sheet of air across the entire length that immediately pulls in surrounding room air (2). An electrically powered ionizing bar (3) fills the curtain of air with positive and negative charges. The airstream delivers these static eliminating ions to the product surface (4) where it is instantly neutralized and cleaned of dust and other particulates.

Enhanced Performance and Reliability Ionizing bars are very ineffective without an air delivery system. When used by itself, a bar must be mounted within an inch of the charged surface to fully neutralize it. This close mounting is impossible when the static is generated in confined areas of a machine. Ion coverage is minimal on oddly configured parts or when high production speeds are involved.

The right type of air delivery is critical. Blowers produce an uneven, turbulent airstream that can cause the positive and negative ions to recombine before hitting the charged material. They are large, suffer mechanical wear and provide limited airflow control. The compact Super Ion Air Knife uses a small amount of compressed air to produce a balanced, laminar sheet of air to carry the ions to the charged surface, even when it is far away. Flow and force are easily controlled and there are no moving parts to wear out.

Added Features

• Compressed air inlets are provided on each end and the bottom of the Super Ion Air Knife. Multiple Super Ion Air Knives can be mounted end-to-end without an air gap.

• Shims can be installed easily if additional hard-hitting velocity is required.

• Primary air does not impact any surface of the Super Ion Air Knife which keeps the sound level low.

• Insertion molded emitter points eliminate potential dirt accumulation that could degrade performance or eventually short the ionizing bar.

• Emitter points are sharp, durable stainless steel.

• The power cable is shielded and has integral grounding. The threaded bayonet connector is fully assembled and ready to use.

• Super Ion Air Knife Kits, which include all components necessary for operation, are available.
