Gen4 Standard Ion Air Knife

A sheet of ionized air is an effective way to eliminate static and clean parts of materials!

What is The Gen4 Standard Ion Air Knife?

EXAIR's Gen4 Standard Ion Air Knife offers 30% improved performance at low pressure allowing you to achieve the same or better results, which saves compressed air and money. They are an effective way to eliminate static, like its "sper" counterpart, the Gen4 Standard Ion Air Knife removes static electricity from plastics, webs, sheet stock and other surfaces where tearing, jamming or hazardous shocks are a problem.

This ionizer uses our original Standard Air Knife to carry ions from a Gen4 Ionizing Bar to the charged surface - up to 20 feet (6.1m) away. Though not as efficient as our Gen4 Super Ion Air Knife (40:1 air amplification), the Gen4 Standard Ion Air Knife (30:1 air amplification) still provides fast static decay and strong blowoff force for cleaning. Force can be adjusted from a "blast" to a "breeze". The Gen4 Standard Ion Air Knife is electrically powered, is shockless and has No Moving Parts.

Why The Gen4 Standard Ion Air Knife?

When air consumption and noise level are not critical to the application, the lower cost makes the Gen4 Standard Ion Air Knife a good choice.

Compressed air inlets are provided on each end of the Gen4 Standard Ion Air Knife. For long spans, multiple Gen4 Standard Ion Air Knives can be mounted end-to-end. This produces an air gap at the connection end of about 2" (51mm). (If no air gap is desired, use the Gen4 Super Air Knife). Special length Gen4 Ionizing Bars up to 119" (3.02m) are available for multiple air knife applications.

How The Gen4 Standard Ion Air Knife Works?

Compressed air flows through the inlet (1) into a plenum chamber. It is then throttled through a thin nozzle (2) extending the length of the Gen4 Standard Ion Air Knife. This primary airstream adheres to the Coanda profile (3), which turns it 90° and directs the flow down the face of the unit. The primary stream immediately beings to entrain surrounding air (4), for an amplifiecation ration of 30:1 at 6" (15xmm) away. An electrically powered ionizing bar fills the curtain of air with positive and negative charges. The airstream delivers these static eliminating ions to the product surface where it is instantly neutralized and cleaned of dust and other particulates.
