The Model 8218 18″(457mm) Gen4 Standard Ion Air Knife System showers parts with static eliminating ions to prevent personnel shocks.
What Is the Gen4 Standard Ion Air Knife?
EXAIR’s Gen4 Standard Ion Air Knife offers 30% improved performance at low pressures allowing you to achieve the same or better results, which saves compressed air, time and money. They are an effective way to eliminate static. Like its “super” 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 ioniser uses our original Standard Air Knife to carry ions from a Gen4 Ionizing Bar to the charged surface – up to 6.1m (20 feet) 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.
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 Ion Air Knife.) Special length Gen4 Ionizing Bars up to 119″ (3.02m) are available for multiple air knife applications.
EXAIR Model 7960 or 7961 Gen4 Power Supply (5kV) is required for bar operation.

Gen4 Power Supplies
Exair Model 7960 or 7961 Gen4 Power Supply (5 kv) is required for ioniser operation. Selectable voltage: for use with all Gen4 Static Eliminators
The Two and Four Outlet Gen4 Power Supplies have selectable voltage, which allows you to choose input voltages of 115VAC or 230VAC. The modular cable with electromagnetic shielding protects sensitive electronics against electromagnetic interference while easing connections and routing. An integrated fuse on the primary protects against voltage spikes.
EXAIR’s Model 7905 Digital Static Meter is sensitive and responsive. It indicates the surface voltage and polarity on objects up to ±20 kV when measured 25mm (1”) away.
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.
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.
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.
