Wherever supply air must travel over long distances from the point of discharge to the occupied zone, jet nozzles are the ideal answer. The airflow direction can be changed to correspond to the heating or cooling mode by adjusting the discharge angle.

The jet nozzle diffusers we produce:
Material: aluminum
Sizes: 100-630mm full sizes
Colors: Powder coated RAL9016,RAL9003,RAL9005(Black)
Nozzle: Can be adjusted 360 degree

In the case of a constant change in the temperature difference between the supply air and the room temperature, the supply airflow will shift up (hot air) or down (cold air)

To produce the tabbed access doors, we use automatic foam sealing machine to produce the PUR foam gasket,which can greatly enhance the air tightness.

Besides,PUR gasket is fitted to the inside and outside of the frame, thus sealing the frame against both the door panel and duct wall. In this case, the air tightness can reach Class D.

If you have interest,I can send you samples so that you can evaluate our quality.

Round swirl diffusers with adjustable blades or fixed blades.

Round swirl diffusers are designed to supply air in heating, air conditioning, and ventilation applications in buildings with high ceilings and temperatures They are appropriate for both industrial and commercial applications.

Their round shape, combined with the helical design of their vanes, causes swirl diffusion of the air stream, resulting in a high induction rate and reduced stratification.

The air diffusion can be changed by adjusting the supply air angle of the synchronously adjustable blades, which changes from horizontal to vertical projection depending on the supply air temperature.

Supply and Exhaust Air Valves are supplied at factory wholesale price.
