Systemair EFF exhaust diffuser with lockable settings.

The EFF is an exhaust diffuser for installation on ceiling or wall. It can also be used for supply air. The diffuser has a lockable central cone which is rotated to adjust the pressure and consequently the air volume.

The EFF is manufactured from sheet steel with a white powder-coated finish (RAL 9010-80) and is available in the following diameters: ø 80, ø 100, ø 125, ø 160 and ø 200. The ø 160 (EFF 160a) size is suitable for both 150 and 160 diameter ducts.

All sizes can be installed directly onto the duct.

The pressure is adjusted by rotating the valve cone.
