EXAIR's Gen4 Super Ion Air Knife static eliminators remove static electricity from plastics, webs, sheet stock and other product surfaces where tearing, jamming or hazardous static discharge is 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.
Gen4 Super Ion Air Knives are available in four different model types:
Gen4 Super Ion Air Knife - includes the Super Air Knife and Gen4 Ionizing Bar assembly.
Gen4 Super Ion Air Knife Systems - include a Gen4 Super Ion Air Knife and Model 7960 Gen4 Power Supply (115V, 230VAC, 50/60Hz).
Gen4 Super Ion Air Knife Kits - include a Gen4 Super Ion Air Knife, Model 7960 Gen4 Power Supply, shim set, filter separator and pressure regulator (with coupler).
Gen4 Deluxe Super Ion Air Knife Kits - include a Gen4 Super Ion Air Knife, Model 7960 Gen4 Power Supply, EFC, Universal Air Knife Mounting System, shim set, filter separator and pressure regulator (with coupler).
Power Supplies - The two (Model 7960) and four outlet (Model 7961) 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. Gen4 Power Supplies are UL Component Recognized to US 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 Gen4 Super Ion Air Knife, it can be mounted on the top. Bottom mounting is possible on Gen4 Super Ion Air Knives that are 18" (457mm) or longer. For the Gen4 Standard Ion Air Knife, it can be top mounted on any length. Bottom mounting is possible on Gen4 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.
Special lengths and unlimited system lengths are available up to 118" (3m) (please contact our factory)
Cable
A 5' length of armored and electromagnetically shielded cable with ground and assembled bayonet connector are included.
Power Supply
EXAIR Model 7960 or 7961 Power Supply (5kV) is required for Super Ion Air Knife operation. Power supplies are equipped with a modular 6' (1.83m) power cord, lighted power switch, integrated fuse on the primary and (2) or (4) high voltage outlets.
Compressed Air
1/4 NPT outlets are provided on each end and the bottom of the Super Air Knife
Electrical
For use with 5 kVrms, 5 milliamperes (max) power supply
Electrical Hazard
Gen4 Ionizing Bars are shockless (less than 40 microamperes short circuited). Do not use near flammable materials or gases.
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.
