Gen4 Super Ion Air Knife™

Powerful static eliminator prevents jamming, tearing, shocks and dust up to 6.1m (20-feet) away!

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

What Is The Gen4 Super Ion Air Knife™?

EXAIR’s Gen4 Super Ion Air Knife offers 34% improved performance at low pressures allowing you to achieve the same or better results, which saves compressed air and money. Gen4 Super Ion Air Knives remove 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, particulate, dust and dirt. Production speeds, product quality, and surface cleanliness can improve dramatically.

The Gen4 Super Ion Air Knife floods an area or surface with static eliminating ions – up to 6.1m (20 feet) away. A uniform 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 Gen4 Super Ion Air Knife is electrically powered, is shockless and has no moving parts. It also requires only 3.7 SCFM of compressed air per foot (305mm) of length at 5 PSIG (105 SLPM per 300mm of length at 0.3 BAR). Sound level is surprisingly quiet at 50 dBA for most applications.

How the Gen4 Super Ion Air Knife™ Works

Compressed air flows through an inlet (1) into the plenum chamber of the Gen4 Super Ion Air Knife. The flow is directed to a precise, slotted orifice. As the primary airflow exits, it creates a uniform sheet of air across the entire length that immediately pulls in surrounding room air (2). An electrically powered Gen4 Ionising 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 instantly neutralises static and cleans off dust and other particulates.

Enhanced Performance and Reliability

Gen4 Ionizing Bars are most effective with an air delivery system that allows the static eliminating ions to reach farther with greater coverage. Gen4 Ionizing Bars are less effective without an air delivery system. When used by itself, a bar must be mounted within 102mm (4”) of the charged surface to fully neutralise 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 Gen4 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.

EFC Electronic Flow Control
Turn off the compressed air when it isn’t needed

EXAIR’s EFC™ is a user-friendly electronic flow control for compressed air that is designed to minimise compressed air use on blowoff, drying, cooling, conveying and static elimination operations. The EFC combines a photoelectric sensor with a timing control that limits compressed air use by turning it off when no part is present. The timing control permits easy tuning to the application requirements while providing flexibility in sensing distance.

Filters, Regulators, Valves & More

With proper filtration of dirt, moisture and oil from the compressed air supply, EXAIR compressed air products will operate for years with no maintenance required. Use a 5 micron or smaller filter separator on the compressed air supply. To prevent problems associated with oil, use a 0.03 micron or smaller oil removal filter on the compressed air supply. Pressure regulators permit easy selection of the operating pressure, providing infinite control of flow, force and air consumption.
