Hvac system aluminum white color air conditioner adjustable louvers 4 way ac diffuser

4 way square ceiling air diffuser

general Information:

The special design of the range of square and  provides to any kind of space the requirements of decoration which today’s architecture demands.

The broad range of products and possibilities to orientate the air flow in 1, 2, 3 or 4 ways, make them particularly indicated for spaces where a particular zone has to be treated, in geometrically irregular spaces or off-centre parts of the space
( conjunction of wall and ceiling, etc.).

By means of laboratory tests it has been demonstrated that these are ideal for variable volume systems, due to its blade design, with which an adherent jet is obtained (Coanda effect) with a highly satisfactory efficiency,specially recommendable in cold air installations.

All square and diffuser types have standardised neck dimensions for duct mounting according to international standard, suitable for most countries.

Ceiling diffusers direct the air from air conditioning systems into the room. 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. Ceiling diffusers allow 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.

Type SCD-VA ceiling diffusers have fixed blades. Horizontal air discharge is four-way.

To give rooms an aesthetic, uniform look, Type SCD-VA diffusers may also be used for extract air.

How to make an aluminum 4-way square air ceiling diffuser?

In order to make a high quality square diffuser, Ventech people introduce a whole production line with advanced stamping, punching machines which are operated by experienced workers.

Firstly, our workers stamp the aluminum profiles, then forward the stamped aluminum profile to punching line. All cores and frames are made by high-efficient machines, then comes to the installation line, we ventech also enjoy the wholly automotive squeezing machines.

Before polishing and filling the putty in the gaps, 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.

Accessories optional:

• Clips
•      A: installation clip, used for connecting the diffuser/ grille to the celing or wall.
•      B: damper fixing clip, used for connecting the diffuser/ grille to the damper.
