What is a Diffuser?

A diffuser is an air outlet designed to distribute supply air evenly into a room in multiple directions and planes.

It delivers conditioned air through vent covers and ensures uniform airflow throughout the space.

Diffusers enhance air mixing by entraining room air into the diffuser’s primary air jet, helping to maintain comfortable indoor conditions.

They help reduce the velocity of supply air as it enters the room and often make use of the Coanda Effect, allowing air to attach to a ceiling or surface for more efficient air distribution.

In addition to functionality, diffusers can also be integrated into architectural ceiling designs to enhance the aesthetic appearance of a space.

Louver Face Diffusers

High-capacity louver face diffusers combine functionality with architectural harmony. They are available with various frame styles, making them easy to integrate into modular ceiling systems.

These diffusers are highly configurable, offering multiple core styles, airflow patterns, and optional features to suit specific applications.

They are ideal for areas requiring large air volumes with low noise and low pressure loss. Concentrated airflow is discharged from each active side, providing long throws — perfect for high-ceiling applications.

Available Sizes:

Neck: 150 × 150 mm — Frame: 295 × 295 mm

Neck: 225 × 225 mm — Frame: 370 × 370 mm

Neck: 300 × 300 mm — Frame: 445 × 445 mm

Neck: 375 × 375 mm — Frame: 520 × 520 mm

Neck: 450 × 450 mm — Frame: 595 × 595 mm

Round Diffusers

Round Ceiling Diffusers combine the elegant appearance of a round cone with high diffusion efficiency. They provide adjustable airflow through several control options, offering the ideal balance between performance and economy.

They are particularly suitable for exposed duct applications, where they deliver a strong horizontal airflow pattern even without a ceiling.

Optional wire guards are available for protection in gymnasium or public-area installations.

Available Sizes: From 150 mm to 350 mm

Radial Diffusers

Radial diffusers feature a circular or square face with multiple fixed or adjustable vanes and a round neck. They are designed for applications that require higher airflow volumes with shorter throws.

These diffusers can produce horizontal or vertical swirl air patterns, ensuring rapid air mixing in both heating and cooling modes.

Thanks to their ability to generate a wide, swirling airflow with quick velocity decay and high induction, they are ideal for providing high airflow rates without drafts at occupant level.

They create a conical swirl pattern for excellent air mixing during cooling.

Radial diffusers can be installed in T-bar ceilings or surface-mounted directly on ductwork. They are available with either side or top inlet connections — the side inlet type is especially suitable for low-ceiling environments.
