Square swirl diffuser:

Square ceiling swirl diffusers in air conditioning systems create a swirl to supply air to rooms. The resulting airflow induces high levels of room air, thereby rapidly reducing the airflow velocity and the temperature difference between supply air and room air. Circular and square ceiling swirl diffusersallow for large volume flow rates. The result is a mixed flow ventilation in comfort zones, with good overall room ventilation, creating only very little turbulence in the occupied zone. Circular and square ceiling swirl diffusers have fixed blades.



1. Materials: Made of high quality GI sheet.
2. Fixed blades.
3. Color: White powder coated RAL9010, or RAL9016
4. Blades have 16 slot, 24 slot, 48 slot available

In order to make a high quality swirl diffuser, Ventech people introduce a whole production line with advanced stamping, punching machines which are operated by experienced workers.
Before polishing, the air diffuser should be washed for 10mins then baked for 30mins.  Power coated is arranged behind the polishing step, by using totally-closed powder finishing line and parching space, the perfect diffuser rolls off the products line and ready to be packed, QC is the priority during each step of the mass productions. We have professional QC to check quality before products go to next step.
