 Round Diffuser  A to Z Products
 Introduction
 
Circular ceiling or duct mounted diffusers, are capable of a high aspiration rate and have the capacity to handle large volumes of air at relatively low sound levels for supply and extract applications, making these diffusers particularly useful for installation in open plan areas such as auditoriums, airport lobbies, supermarkets and factories.

Round diffusers are always considered as heavy duty air distribution devices having a wide range of applications in heating, air conditioning and ventilation systems. Round diffusers provide an unusually uniform horizontal airflow patterns.
They are intended for application in air conditioning and ventilation systems in civil as well as industrial zones. Suitable for cooling and ventilation systems for wide diffusion effect.

Round diffuser can be installed on false ceiling or exposed duct work. They offer a unique role in diffusing and exhausting air to and from the conditioned space. Suitable for offices, shops or similar premises where adjustable patterned diffusion is essential for cold air distribution.

COSMOS make round diffusers are designed for the applications of HVAC systems with high performance and noise‐free operation. Round diffusers have the capacity to handle large volume of air at low sound levels for supply and extract applications. The diffusers deliver the air in a true 360 degree radial horizontal pattern and produce excellent performance in variable air volume systems.

COSMOS round diffuser give one more option to the interior designer, to provide draft‐free supply air to air conditioned spaces. A removable core only simplifies installation but also improves aesthetics by eliminating all visible holding screws.

COSMOS round diffuser model ARD can be used almost all installations. They can be supply as diffuser face only, and as a diffuser combined with volume control damper.

The plenum box can be supplied with top or side entry spigot and volume control damper if required.
