(A) Compressed air flows through the inlet at the rear (or end) ports, and into a plenum chamber.
(B) As the compressed air stream leaves the Air Knife, the surrounding air is entrained into the airflow for an amplification ratio of 30:1 @ 6" away and adheres to the coanda profile.
(C) The airflow now turns 90 and travels down the front face of the Air Knife. The amplified air stream is a hard-hitting sheet of laminar flow with minimal wind shear, which translated into reduced energy use in blow-off and cooling.
