EXAIR GEN 4 Super Ion Air Knives remove static electricity from plastics, webs, sheet stock and other product surfaces where tearing, jamming, debris or hazardous shocks are a problem. The laminar sheet of air sweeps surfaces clean of static, particulate, dust and dirt. Production speed, product quality and surface cleanliness can improve dramatically.
The GEN 4 Super Ion Air Knife floods an area or surface with static eliminating ions – up to 20 feet (6.1 m) 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 GEN 4 Super Ion Air Knife is electrically powered, shockless and has no moving parts. It also only requires 3.7 SCFM of compressed air per foot of length at 5 PSIG (105 SLPM per 300mm of length at 0.3 BAR). The sound level is also surprisingly quiet at 50dBA for most applications.
Compressed air flows through an inlet (1) into the plenum chamber of the GEN 4 Super Ion Air Knife. The flow is directed to a precise, slotted orifice. The primary air flow exits, it creates a uniform sheet of air across the entire length that immediately pulls in surrounding room air (2). An electrically powered GEN 4 Ionizing Bar (3) fills the curtain of air with positive and negative charge. The airstream delivers these static eliminating ions to the product surface (4) where it instantly neutralizes static and cleans dust and other particulates.
EXAIR’s GEN 4 Super Ion Air Knives offer a convenient, safe and reliable method for eliminating static charge while improving efficiency and quality. If you have questions or need help selecting the right product for your application please contact on of our Application Engineers.
