The process of distributing heated or cooled air throughout your home should be seamless. The right air conditioning diffuser ensures optimum airflow performance.
An air con diffuser directs and controls airflow in an air conditioning system. It is a critical component of heating, ventilation, and air conditioning (HVAC) units. In ducted air conditioning, the diffuser delivers air to each zoned area.
Air con diffusers are available in different shapes, including square, circular, or rectangular. They can be made from a variety of materials such as plastic, aluminium, stainless steel, timber, or cast iron. Diffusers also come in different configurations, such as swirl diffusers and slot diffusers.
A linear slot diffuser is a modern and flexible type of air con diffuser. With its long, narrow design, it allows airflow to be directed in multiple directions. This makes it easy to install in tight spaces and helps conceal the diffuser for a more discreet, aesthetically pleasing look.
The size of an air con diffuser refers to the diameter of the neck where the flexible duct connects. Correct sizing depends on factors such as the area to be cooled or heated, room dimensions, ceiling height, and the overall look of the space.
For example, an average bedroom measuring 3m x 3m usually requires a 200mm round diffuser.
Small rooms
The ceiling is generally the preferred location for diffusers with horizontal airflow.
Large rooms/areas
Example: A living room measuring 6m x 4m with a 2.7m ceiling should have two 200mm diffusers – one placed 2m from a long wall and 2m from a short wall, and the second placed 2m from the opposite end wall.

The final layout should always be decided in consultation between the installer and the client.
