Air knives by EXAIR Corporation use little compressed air and energy

EXAIR offers different models of air knives.

EXAIR Corporation has a portfolio of industrial compressed-air solutions unlike any other in North America. The lineup includes an impressive family of engineered air knives, which reduce compressed-air use and noise significantly in comparison to competitors’ similar products. This group comprises three distinct devices: the Super, Standard, and Full-Flow Air Knife.

Due to the small profiles of these instruments, users can mount the air knives to accommodate many applications involving conveyors and webs – even in tight spaces.

Aluminum, stainless steel, and PVDF

These air knives use less energy and air than other blow-off products do by entraining high volumes of room air. EXAIR manufactures these products in aluminum, stainless steel, and PVDF for corrosive work environments. The stock sizes run from 76 to 2,743 millimetres, and customers can request special order lengths.

The most efficient means of cleaning, drying, or cooling parts, webs, and conveyors, the Super Air Knife delivers a uniform sheet of laminar airflow across the full length with hard-hitting force, and the noisy blow-off of other air knives is reduced to a whisper; the sound level is a mere 69 dBA for most applications, even at pressures as high as 80 psig. The Super Air Knife produces an air-amplification ratio (i.e., entrained air to compressed air) of 40 to one, and it complies with the maximum dead-end pressure and noise requirements of the United States Occupational Safety and Health Administration.

The Standard Air Knife offers good performance with a 30-to-one air-amplification ratio, and EXAIR recommends it as a less expensive alternative to the Super Air Knife. Available in aluminum and 303 stainless steel, the Standard Air Knife is louder and uses more compressed air than the Super option, and it has compressed-air inlets on each end.

The Full-Flow Air Knife is the least expensive option and perfect for tight spaces, with a 30-to-one air-amplification ratio. This air knife has compressed-air inlets on the rear, with air consumption and sound levels between those of the Super and Standard air knives.

Headquartered in Cincinnati, EXAIR Corporation has designed, manufactured, and supplied compressed-air equipment for industrial facilities since 1983.
