TSF-F Basic Diffusers

The TSF-F square perforated diffuser has a simple and safe design for easy installation in T-bar suspended ceilings. It is primarily intended for air extraction. It has a recommended installation height of up to 4 metres. It has low installation space height requirements and it’s widely used in offices, schools, medical premises, shops, halls and corridors. The TSF-F is operable without a plenum box and can be connected directly to the duct bend or tee. It has a well-balanced ratio between airflow capacity, pressure drop and sound generation. 

The TSF-F is made from galvanised steel sheet with a powder paint surface finish. It consists of a backing box with a circular duct connection equipped with a rubber gasket and the perforated front plate. The front plate holds in the backing box by simple hinges on one side and by spring fixing brackets on the other side. It can easily be detached and can be opened without tools by using a folding ear on the edge of the plate.
