EXAIR's Super Air Knife™ is a quiet, hard-hitting curtain of air for blowoff, cleaning, drying, and cooling, dramatically reducing compressed air usage and noise when compared to other blowoffs. The Super Air Knife offers a more efficient way to clean, dry or cool parts, webs or conveyors. It delivers a uniform sheet of laminar airflow across the entire length with hard-hitting force. Even at high pressures of 80 PSIG (5.5 BAR), the sound level is surprisingly quiet at 69 dBA for most applications! See the CE compliant Super Air Knife in action!
