EXAIR's Super Air Knife™ dramatically reduces compressed air usage and noise when compared to other blowoffs. It offers a more efficient way to clean, dry or cool parts, webs or conveyors and delivers a uniform sheet of laminar airflow across the entire length. Noisy blowoffs become a whisper when replaced with the Super Air Knife. Even at high pressures of 80 PSIG, the sound level is surprisingly quiet at 69dBA for most applications! Air amplification ratios of 40:1 are produced. Watch our Super Air Knife in action. » Learn More
