3-Way Ceiling Diffuser -

3-Way Ceiling Diffuser

Product Overview

Louvre faced ceiling diffusers with three-way blow blade configuration are constructed entirely from aluminium including the frame, blades and centre core.

CVE Shop louvre faced diffusers are lightweight and will not rust nor corrode. They feature a welded core & frame for strength.

They provide excellent diffusion performance, and are suitable for surface mounting in plasterboard ceilings or lay-in ceiling grids (600mm x 600mm grid). Select CVLFD3-450 for the tile replacement diffuser.

The removable core makes them easy to install, clean & access any dampers located behind the diffuser.

The louvre faced ceiling diffuser is suitable for use where cooling is required in areas of high heat and high humidity, and also to suit heating & cooling applications in cooler temperatures.

To obtain a varying distribution pattern, triangular blanking plates can be fitted behind the louvre, thus maintaining a uniform face appearance.
