EXAIR Standard Air Knife

What is the Standard Air Knife? A quiet, energy efficient way to clean, dry or cool parts, webs or conveyors. The Standard Air Knife utilizes the coanda effect (wall attachment of a high velocity fluid) to create air motion in its surroundings. Using a small amount of compressed air as a power source, the Standard Air Knife pulls in large volumes of surrounding air to produce a high flow, high velocity curtain of air for blowoff. 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-out is normally measured in weeks, not months or years. The Standard Air Knife dramatically reduced "wind shear" by gradually introducing the entrained air to the ejected compressed air.
