EXAIR has been manufacturing Intelligent Compressed Air® products since 1983. In the beginning, the Standard Air Knives and Full Flow Air Knives were very effective at that time. But as leaders in this market, EXAIR did not want to stop there. We were able to engineer a more efficient, more powerful, and much safer air knife, the Super Air Knife. In this blog, I will discuss the features and benefits that the Super Air Knives can offer.
Bernoulli’s principle explains how a high velocity fluid can generate a low pressure. The Super Air Knife creates that high velocity air stream to produce a low pressure above and below the opening to entrain ambient air. What does this mean for you? It will save you much money by using less compressed air. The mass of the free ambient air is added into the air stream to give a strong blowing force. The Super Air Knife has an amplification ratio of 40:1. For every 1 part of compressed air, 40 parts of ambient air is drawn into the blowing air stream. Ambient air is free, and compressed air is definitely not. EXAIR was able to engineer a design to use the Bernoulli’s principle to make one of the most efficient air knives in the market place.
As a benefit, they blow a laminar air stream which reduces noise levels and create a consistent force along the entire length. An even force will give you tighter control for blowing applications which will cut compressed air usage unlike the inconsistent and turbulent air flows caused by drilled pipes, manifolds of nozzles or blower-type systems. Some other interesting features for the Super Air Knives are that they have a compact design to fit into tight places for blowing and cooling. The footprint is very small as compared to blower-air knife systems. They do not have any moving parts to wear or maintenance to do. They only need clean compressed air to work.
