The Curtain Transvectors' amplification uses an impulse principle to accelerate a large mass of stationary air with a thin sheet of sonic-velocity compressed air.
When compressed air enters the Transvector, it fills a plenum which has only one exit path - a linear .002" gap running the length of the curtain. As the air is forced out of the orifice, it accelerates and collides with surrounding air entraining a great volume of free, ambient air. The result is an air knife that delivers a large volume of output air in return for a small amount of compressed air.
