Air Knives

Quiet, hard-hitting curtain of air for Blowoff, Cleaning, Drying and Cooling - WITH NO MOVING PARTS!


EXAIR's Air Knives dramatically reduces compressed air consumption when compared to other blowoffs. It delivers a uniform sheet of laminar airflow across the entire length with hard-hitting force. Meets OSHA maximum dead-ended pressure and noise requirements.

Advantages:

  • Surprisingly Quite ! Only 69 dBA!
  • Reduced Air Consumption!
  • Uniform Airflow!
  • 40:1 Air Amplification!
  • No Moving Parts - Maintenance Free!

Featured Products:

  • 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.
  • Standard Air Knife, a good choice when a less expensive alternative is required.
  • Full-flow Air Knife, this low cost choice provides a curtain of air for blowoff, cleaning, drying and cooling.
  • Special Air Knife, suited to specific application requirements.

Which Air Knife Is Best For Your Application?

EXAIR manufactures the Super Air Knife, Standard Air Knife and Full-Flow Air Knife. The table below provides a quick comparison of the three styles.

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.

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.

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.

Velocity and force measured at 6" (152mm) from target. Sound level measured at 3' (914mm). All measurements taken at 80 PSIG (5.5 BAR).
