The CON-TROL-CURE® AIR KNIVES
are a quiet, energy-efficient way to cool substrates as they exit the cure chamber. Utilizing the coanda effect to create high velocity air motion, the Air Knife requires only minimal compressed air as its power source.
As compressed air flows through the inlet and into a plenum chamber, it is throttled through a thin nozzle extending the length of the Air Knife. This primary air stream adheres to the coanda profile which turns it 90, and directs it to flow down the face of the knife. The primary stream immediately begins to entrain surrounding air, while velocity loss is minimized through the wall attachment effect.
Interaction of the ejected and entrained air dampens "air shear", reducing noise levels dramatically. The result is a high velocity, high volume sheet of air achieved at minimum noise level. Entrained air to compressed air ratios of 30:1 are achieved with this unique knife. Compared to a 3:1 ratio for drilled or slotted pipe, you can achieve an air savings of 40 to 90%! Available in lengths of: 6", 12", 18", 24", 30", and 36".
