Air Directional Nozzles and Jet Diffusers

NozzFlow™ nozzles

FabricAir offers multiple directional flow models. Two of these are exceptionally suitable in applications that require high precision, namely NozzFlow™ and JetFlow™.

As the air is discharged from the duct, the air stream begins to expand and mix with the room air. The momentum slows the further the air travels from the outlet, and the room air is entrained. With NozzFlow™ and JetFlow™ there is more momentum to be spread because these technologies have a higher discharge coefficients. 

NozzFlow™ and JetFlow™ have discharge coefficients of between .9-.98. In comparison, SonicFlow™ and OriFlow™ have discharge coefficients of .62. Using jets, the air leaves the duct closer to perpendicular, therefore allowing the air to penetrate further in the direction in which it is aimed.

High precision throws can be very useful when, as an example, trying to get air down a narrow aisle of a food storage facility.

JetFlowTM is capable of generating exceptionally long throws through the use of conical jets in varying diameters. The jets have a very high discharge coefficient due to the conical shape.

NozzFlowTM is used in applications where very precise directional airflow is needed. The discharge coefficient is almost at unity due to the shape of the nozzle.

Nozzles and Jet diffusers increase the throw length by accelerating the flow of air through the reduced diameter of the opening formed by the device.
