CRA Circular Diffuser

The CRA diffuser is an adjustable supply air pattern diffuser that offers architecturally appealing styling with maximum diffusion efficiency and flexibility. All of the diffusers in the CRA range have three cones to maintain a uniformity of appearance. In standard form, the diffuser is manually adjustable to change the supply air pattern from a horizontal for cooling to a vertical discharge for heating. The adjustment is made by turning the small centre cone to provide horizontal throw in the down position and vertical throw in the up position. The radial supply air pattern of the CRA diffuser means the diffuser has an inherent ability to maintain a ceiling effect making the diffuser suitable for variable air volume applications. The radial supply air pattern also means that the diffuser still delivers the air horizontally even when there is no ceiling present making it ideal for use with exposed duct systems.
