Gen4 Super Ion Air Knife

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

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 Knife remove static electricity from plastics, webs, sheet stock and other product surface 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.

Why The Gen4 Super Ion Air Knife?

The Gen4 Super Ion Air Knife floods an area of surface with static eliminating ions - up to 20 feet (6.1m) 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 compresed air per foot 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.

Uses The Super Air Knife:

  • Low air consumption!
  • Surprisingly quiet!
  • Uniform airflow!
  • End and bottom air inlets!

How The Gen4 Super Ion Air Knife Works?

Compressed air flows through an inlet 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. 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.

Case Study:


The Problem: Car bodies are primer coated, then sanded before entering the paint booth. Priming dust, attracted to the car body by a static charge, creates imperfections that are captured and magnified in the painting process.

The Solution: An “archway” of Model 112024 24" (610mm) Gen4 Super Ion Air Knives was installed upstream of the paint booth. As the car bodies pass through, a high velocity sheet of ionized air neutralizes the static charge to release the dust and blow it toward a collection system.

Comment: Non-turbulent airflow was the reason this cleaning system worked so well. The compact Gen4 Super Ion Air Knife has the ability to move the bulk of the static eliminating ions to the car surface. It can be adjusted from a gentle breeze of air to a pounding blast, with instant “on/off ” capability. Uniform airflow across the entire length assures that all car body surfaces are neutralized and dust free. Best of all, the Gen4 Super Ion Air Knife is easy on the compressed air system and workers' ears. They use much less compressed air than standard blowoffs and are around 69 dBA in most applications. EXAIR's EFC is an electronic flow control for compressed air. It can sense when there is no car present and will automatically turn off the compressed air until the next car is moved into position. It is a perfect addition to this type of application.

Here are some sample of applications:
