Louvre Face Ceiling Diffuser

Type LFD Supply & Extract

The crisp extruded lines of Tek’s all aluminium louvre faced diffusers have been designed to be both aesthetically pleasing and to integrate with both concealed tee bar and regular suspended ceiling grids, plus lay in grid mounting. The diffuser is available with either a surface mounted frame to suit plaster and other conventional ceilings, or a recessed frame for a ceiling tile replacement.

Air patterns of one, two, three or four-way cores are available and we specialise in oblong or irregular shaped units. The recommended uses of these units are for the ceiling supply and extract of conditioned or treated air in offices, schools and hospitals, shops or meeting halls etc. They are suitable for handling air change rates up to fourteen changes per hour, dependent on ceiling heights and air temperature differentials.
