EXAIR's Super Air Knife is engineered to provide a powerful, uniform flow of air that is ideal for production line blowoff, cleaning, or cooling. Its highly efficient design uses compressed air to produce a laminar stream of air that draws in surrounding air at a ratio of 40 to 1! The Super Air Knife has a compact profile that can easily fit in tight spaces. It's quiet and meets OSHA maximum dead-end pressure and noise requirements. Stock lengths are available up to 108" (1372mm).
