The Type BSE shut-off dampers provide fire resistance to class K90-18017.

The WBE can be mounted in walls and ceilings.

No special fixing methods are required (This is time saving and very economic).

The shut-off dampers may be used in ventilation systems in accordance with DIN 18017-3 for supply and return air. They can be mounted inside and outside of F90/F30 shaft partitions or L90/L30 classified system-tested ducts and with, or without, mortar (wet or dry installation).
