The WKZ-O damper can only be mounted in a vertical partition (rigid wall),
The WKZ-O damper can only be installed with a horizontal axis of rotation.

The WKZ-O fire dampers are certified for fire resistance class:
EI 240 (ve i↔o) S

Where:

E – fire integrity,
I – fire insulation,
S – dsmoke leakage,
240– duration of fulfilment of E, I and S criteria, in minutes,
ve – a damper mounted in a vertical partition (wall),
i↔o – operating effectiveness criteria are met from inside to outside (fire inside), and from outside to inside (fire outside).
