These days, the buildings are generally incomplete if they don’t have the HVAC systems. In our native countries, the building models are not accepted unless it has a well-organized air duct system for Heating and Ventilation.
The air duct system is an important facility that should be there in each and every building. There are two main devices used in HVAC systems that are air grilles and diffusers (also known as “ตะแกรงอากาศและตัวกระจายอากาศ” in the Thai language).
A grille is used in conveying and removing air vertically without any kind of deflection. A device used to direct the air at various angles with their special blades when the air is leaving the unit and going into space is known as a diffuser.

HVAC systems are essential in the buildings and they are incomplete without air grilles and diffusers. They are essential in ventilation systems because they complete the whole system of these centralized duct systems.
Air grilles normally have straight openings, and they are installed at the opening of the duct system. The diffusers have parallel angles plates which are moveable and used to direct air in a specific direction in a room.
These devices are usually mounted in the walls, doors ceiling, and in ducts and their color may vary. They are also fixed on the floors. You can easily purchase them according to your requirements.
