Air Knife Comparision

Which Air Knife Is Best For Your Application?

EXAIR manufactures the Super Air Knife, Standard Air Knife and Full-FlowAir 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 effi cient. 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 airfl ow.

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

The Full-Flow Air Knife provides good performance with a 30:1 air amplifi cation 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 smalladditional charge, however they are not recommended for applications where uniform fl ow across the length is required.
