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

Advantages

  • Up to 10 dBA noise reduction
  • Reduced air consumption
  • 30:1 air amplification
  • Aluminum or stainless steel
  • Compact, rugged, easy to install
  • Stock lengths up to 48" (1219mm)
  • No moving parts
  • Compressed air inlets on each end
  • Variable force and flow

Materials

Aluminum - The aluminum Standard Air Knife is suited to a wide variety of environments where corrosion or contamination is not a factor. The aircraft grade aluminum construction with plastic shim is very durable for general purpose applications. Stainless steel screws are used to eliminate corrosion in damp locations. It can withstand temperatures up to 180°F (82°C).

Type 303 Stainless Steel - This is the most common grade of stainless steel. It offers good strength and is best suited to mildly corrosive environments. It can withstand temperatures up to 800°F (427°C).

Air Knife Models

EXAIR Super Air Knives

The Super Air Knife provides the best performance with a 40:1 air amplification ratio, making it the most efficient. It is the best choice for all applications. The Super Air Knife has a laminar airstream that is uniform, forceful and quiet. Velocity is the highest of all three air knives. Air consumption is lowest of all three air knives. Compressed air inlets are provided on each end and on the bottom. Multiple Super Air Knives can be mounted “end to end” for longer lengths of uninterrupted airflow.

EXAIR Standard Air Knives

The Standard Air Knife provides good performance with a 30:1 air amplification ratio that is less efficient than the Super Air Knife. It is a good choice when a less expensive alternative is required. The Standard Air Knife has an airflow that is also uniform and forceful. It is louder and uses more compressed air than the Super Air Knife. Compressed air inlets are provided on each end. Overall length is 1" (25mm) longer than the airflow length.

EXAIR Full Flow Air Knives

The Full-Flow Air Knife provides good performance with a 30:1 air amplification ratio. The Full-Flow Air Knife is the least expensive and is a good choice for tight spaces. Force is less than the other two styles. Air consumption and sound level falls between that of the Super Air Knife and the Standard Air Knife. Compressed air inlet(s) are provided on the rear. Inlets are available on each end at a small additional charge, however they are not recommended for applications where uniform flow across the length is required.

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.

Sound level dBA 90 91 95 97 100 105 110
