The volume diffusers enhance indoor air quality by lowering airborne contaminants such as dust mites. They reduce noise levels. 

How does a variable air volume diffuser work? 

A variable air volume diffuser works by creating an airflow pattern inside a room. Mixing hot and cold air allows a variable diffuser to achieve a more uniform temperature across the space. It helps remove harmful particles from the air by combining high velocity and low-pressure airflow. 

Different Types of Air volume diffuser:

There are different types of variable air volume diffuser that are stated below. 

  • Vent cap diffuser: Vent cap is appropriate for the general building's exterior wall exhaust. This form is intended for the buildings and the home's kitchen and bathroom. The exterior wall is attached to the exhaust duct's termination. It has the result of making the outer wall more attractive. The Vent cap has louvers and stainless-steel netting to keep insects out.
  • Advantages: 
    • Featuring stainless steel bug mesh and air intake louvers
    • Water-resistant kind
    • Appearance is good
  • Waterproof Louver

The waterproof louver consists of a frame and a horizontal blade assembly made of a high-quality extruded aluminum profile structure, which benefits corrosion resistance and rigidity. Designed and rated to offer ample volume ventilation for both intake and exhaust. The back-mesh net on shutters prevents bugs from entering the interior while preventing any rain from entering. They are both fireproof and waterproof.


Primarily used for installing curtain walls, windows, and partitions

Offers superior weather protection in vulnerable places

The blade's upper edge incorporates a return bend that may successfully stop the backflow in rainy and windy situations.

Appropriate for applications requiring intake and exhaust ventilation

Open-Hinged Air return grille FK006

An open-hinged air return grille that resembles a door also has the features of a filter screen. For the hinged air return grille, an openable filter that can be opened and taken out for cleaning can be installed behind the louvre. To make it easier to repair and clean the return air filter, there is no need to remove the louvre return air outlet.

Square ceiling diffuser:

A 4-way airflow pattern is typical of square ceiling diffusers. These ceiling vents, which may be utilized for new construction and retrofit installations, have extruded aluminum diffusers and call for the proper collar and fan blade damper on the rear.

Jet diffuser: 

  • Jet-nozzle diffuser: 

Jet nozzle diffusers are suitable for supplying cooled and heated air over large areas. The jet nozzle achieves ideal noise control due to its optimal aerodynamic nozzle structure design. Its high-quality shape design can be used in concert halls, theaters, museums, and other high-end places.
