OPTONE + Grille

The OPTONE.H + GRILLE smoke exhaust damper features a frame supporting the gate. It offers free passage > 20 dm.

The damper is controlled via a 24 V DC electric remote control, using a shunt trip from the smoke exhaust control panel, e.g. ORDONE.
The damper is made of aluminium and houses the removable core of the finned grille. It is drilled in the upper left corner to enable the passage of cables. It is fitted with surrounding seals for maximum air tightness.
