The Standard Air Knife is EXAIR's original air knife design. It uses a Coanda profile which turns the airflow 90 degrees from its outlet. This creates a low pressure area capable of entraining ambient air at a ratio of 30:1 while producing a powerful airflow; but does have a higher operating cost than the Super Air Knife. Available from stock in 3" to 48" lengths and made from aluminum or Type 303 stainless steel. Custom sizes and materials are available.

Applications

  • Part drying after wash
  • Sheet cleaning in strip mills
  • Conveyor cleaning
  • Web drying or cleaning
  • Part or component cooling
  • Environmental separation
  • Pre-paint blowoff
  • Bag opening/filling operations
  • Scrap removal on converting operations

How the Standard Air Knife Works

How the Standard Air Knife Works

Compressed air flows through the inlet (1) into a plenum chamber. It is then throttled through a thin nozzle (2) extending the length of the Standard Air Knife. This primary airstream adheres to the Coanda profile (3), which turns it 90° and directs the flow down the face of the unit. The primary stream immediately beings to entrain surrounding air (4), for an amplifiecation ration of 30:1 at 6" (152mm) away.

Efficiency Lab

Does your company currently use a blowoff product similar to EXAIR’s that you’d like us to evaluate? Ship it to the EXAIR Efficiency Lab! Our qualified staff will test it for FREE, using EXAIR’s calibrated testing equipment. We’ll compare the performance of your existing product (air consumption, effectiveness, noise levels, efficiencies, etc) with the EXAIR Intelligent Compressed Air® products. The results will be published in a comprehensive report that includes a cost savings analysis. For most applications, EXAIR products can help you improve your efficiency AND typically pay for themselves in a matter of weeks.

OSHA Maximum Allowable Noise Exposure

High noise levels are a common problem for many plants. Compressed air noise often exceeds OSHA (Occupational Safety and Health Administration) noise level exposure requirements, resulting in hearing loss to those working in close proximity. The sound level of the Super Air Knife is quiet at 69 dBA, even at high pressures of 80 PSIG (5.5 BAR). Using the Super Air Knife, it is possible to obtain hard-hitting force without the high noise.

OSHA Maximum Allowable Noise Exposure

Hours per day (constant noise) 8 7 4 3 2 1 0.5
Sound level dBA 90 91 95 97 100 105 110
OSHA Standard 29 CFR - 1910.95(a)
