VVKR-F Swirl Diffusers

The VVKR-F is a square swirl diffuser complete with adjustable deflectors. Available in different sizes, it is designed for easy installation in T-bar suspended ceilings. It has a wide range of applications and is typically installed in offices, schools, medical premises, public halls, reception areas and corridors. It is intended for air supply and can eventually also be used for air extract. The recommended installation height is up to 4 m. 

The VVKR-F has an excellent induction rate even at low airflow volumes and provides a well-balanced ratio between airflow capacity, pressure drop and sound generation. The VVKR-F is made from galvanised steel sheet with a powder paint surface finish. It consists of the backing box, which has a circular duct connection and the front plate with adjustable polymer deflectors. The outer shape of the backing box had been designed to fit into T-bar ceiling frames. The front plate can be opened or detached easily without tools via a folding ear on the edge of the plate.
