Louvred Face Diffuser 6500 Series Advanced Air

The Advanced Air Model Series 6500 Pattern Ceiling Diffusers have been specially designed to provide a high capacity louvred face directional diffuser that can supply large volumes of air at relatively low sound levels and pressure drops. An engineered blade design with a 6mm horizontal lip on all angular discharge louvres creates a stable horizontal air pattern that is tight to the ceiling.

Louvred Face Diffuser 6500 Series Advanced Air

Ideal for applications in VAV systems, these diffusers create a strong ceiling coanda effect at typical maximum and minimum airflow rates and ensure draft free air distribution. 

Available with a wide variety of core styles and neck sizes, a combination can be selected to suit a specified air pattern and deliver the desired volume of air to suit any particular requirement. Many frame types are also available to suit almost any mounting condition including surface mount (flat, beveled or deep drop face) and T-Bar panel types (Standard 25mm, Threadline, Fineline, Spline,

Tegular or Metal Snap-in). These models therefore offer a great degree of design flexibility.

The Advanced Air Model Series 6550 Adjustable Pattern Ceiling Diffusers offer the same features as the 6500 Series, however, they feature four hinged, individually adjustable deflecting vanes. These vanes allow air pattern adjustment from horizontal to vertical and further enhance the flexibility of the diffuser. Ideal for applications with higher ceiling heights or for heating applications to minimise stratification.
