Gen4 Standard Ion Air Knife Kit
Gen4 Deluxe Standard Ion Air Knife Kit
Power Supplies - The Model 7960 (2 outlet) and Model 7961 (4 outlet) selectable voltage power supplies are available for 115 VAC or 230 VAC, 50/60Hz systems. A 6' (1.83m) modular power cord and lighted power switch are included. Power Supplies are UL Component recognized to U.S. and Canadian Standards, and are CE and RoHS compliant.
Universal Air Knife Mounting System - The Model 9060 Universal Air Knife Mounting System is used to provide secure, precise positioning for any of the EXAIR Air Knives. The Air Knife can quickly and easily be moved within close proximity of the part to improve effectiveness. The Universal Air Knife Mounting System has a durable, stainless steel construction that is suitable for a variety of industrial applications.
For the Standard Ion Air Knife, it can be top mounted on any length. Bottom mounting is possible on Standard Ion Air Knives that are 9" (229mm) or longer.
The Universal Air Knife Mounting System can be articulated into any position and provides a maximum extension of 30" (762mm). A 1/2" diameter hole is required for mounting. Alternatively, the bolt can be threaded directly into a 1/2"-13 tapped hole. For any style Air Knife that is 24" (610mm) to 54" (1372mm), use (2) Universal Air Knife Mounting Systems. For knives 55" (1397mm) - 71" (1803mm), use (3). For 72" (1829mm) - 95" (2413mm), use (4). For knives 96" (2438mm) and over, use (5).
Air Knife Plumbing Kits - Super Air Knives that are 24" or longer must be supplied with compressed air at multiple inlets on the knife. Air Knife Plumbing Kits prevent you from searching for the right fittings or using undersized air supply lines. They provide properly sized compressed air hose or pipe, and fittings to interconnect the bottom or end compressed air inlets for best performance. Plumbing kits for aluminum Super Air Knives include a pressure gauge to monitor pressure at the Super Air Knife, which is an indication of proper air supply. They also include nitrile/PVC hose and brass fittings.
Coupling Bracket Kits - Some applications require a Super Air Knife that is longer than our 108" (2743mm) length. Coupling Bracket Kits that join two Super Air Knives together are available. The kit includes two rigid plates along with the assembly screws. The bottom plate is supplied with a hole to access the bottom compressed air inlets. All models include stainless steel screws.
Air Knife Shim Sets - Compressed air exhausts through a gap in the Air Knife which is set with a shim. Force and flow may be increased by adding shims.
Shim sets for aluminum Super Air Knives include a .001" (0.03mm) Amber color, .003" (0.08mm) Green color, and .004" (0.10mm) thick Tan color plastic shim . A Red color .002" (0.05mm) thick shim comes installed in the Super Air Knife.

Gen4 Standard Ion Air Knife Dimensions
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 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 amplification ratio 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.
Gen4 Super Ion Air Knife Standards and Certifications
EXAIR's Gen4 Super Ion Air Knife complies with OSHA's Safety Requirements, the EU General Product Safety Directive (2001/95/EC) and meet the noise limitation requirements of the EU Machinery Directive (2006/42/EC). All sound level measurements are taken at 3 feet away.
Gen4 Ionizing Bars and Gen4 Power Supplies are UL Component Recognized to U.S. and Canadian safety standards, and are CE and RoHS compliant.

Selecting the Right EXAIR Static Eliminator
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 minimized 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 a Gen4 Ionizing Bar without air delivery positioned one-half inch (13mm) from the surface.
The Gen4 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 ionized air effective up to 20 feet (6.1m) away.
The Gen4 Standard Ion Air Knife uses our Standard Air Knife (30:1 air amplification) to deliver a sheet of ionized air to the surface. Air consumption and noise are somewhat higher than the Gen4 Super Ion Air Knife.
The Gen4 Super Ion Air Wipe clamps around the part and creates a ring of ionized airflow. It neutralizes and cleans continuous moving surfaces.
The Gen4 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 new patent pending Intellistat Ion Air Gun produces ionized compressed air to neutralize static and remove troublesome particulates during clean processes, test procedures and sensitive assembly work, particularly in laboratories, clean rooms or scientific testing facilities. With a +/-30 volt balance the Intellistat was designed to use minimal compressed air while delivering precise blow-off and exceptional static decay rates capable of reducing 5000 volts to less than 500 in under one second.
The Gen4 Ion Air Gun uses our High Velocity Air Jet (5:1 air amplification) to provide a narrow beam of ionized airflow. This hand-held static eliminator is rugged for industrial use and has incredibly fast static decay rates.
The Gen4 Ion Air Jet uses our High Velocity Air Jet (5:1 air amplification), and is an effective spot cleaner. Available for permanent mount or with flexible Stay Set Hose, this ionizer is the ideal way to focus an ionized 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 ionizers for these critical applications.
Gen4 Ionizing Bars are ideal for relatively flat materials, where the bar can be mounted close to the product surface. The Gen4 Ionizing Bar is compact, allowing it to fit in the confined spaces of machinery, where the charge is generated.
The Gen4 Ionizing Point is effective for spot neutralization. The compact size makes it ideal for winding or slitting operations. It can also be mounted through a duct to neutralize static charges due to moving air or materials.
Special Static Eliminators
EXAIR manufactures static eliminators suited to specific application requirements. This special ionizer was developed for the automotive industry. This air amplifier and ionizer combination is used to dry water based paints on car bodies while eliminating the possibility of a static charge that might attract dust or other contaminants.
