Hard hitting curtain of air for web, sheet and part blowoff.

What Is The Standard Air Knife?

A noiseless, energy competent way to clean, dry or cool parts, webs or conveyors. They provide a compact and efficient means to dry, clean and cool materials. Standard Air knives operate by entraining the surrounding air along with the compressed air utilizing the “coanda” effect essentially converting energy which would normally be lost as noise and pressure drop into useful flow. The standard Air Knife uses a small amount of compressed air as power source & draws in large volumes of surrounding air to produce a high flow, high velocity curtain of air for blow off.

Why the Standard Air Knife?

Amplification ratios (entrained air to compressed air) of 30:1 are achieved with the Standard Air Knife, compared to 3:1 for drilled or slotted pipe. Air savings of 40% to 90% are possible when replacing these "homemade" blowoff devices. Pay-back is normally measured in weeks, not months or years.

The Standard Air Knife dramatically reduces "wind shear" by gradually introducing the entrained air to the ejected compressed air. Noise level is typically cut in half. The result is a high velocity, high volume sheet of air with reduced noise level and air consumption.
Drilled pipe or open jets, by contrast, provide minimal air amplification. They also produce unacceptably high noise levels as the compressed air shears into the still air.
