ESSMANN® double flap for automatic ventilation in the event of a fire and thermal ventilation.
Manufactured from a welded aluminium profile construction with two flaps, which open from the longitudinal sides. The flaps slope towards the central rain gutter at an angle of 6° in order to keep them clean and drain water away.

The flap is fitted with two pneumatic cylinders for opening and closing. The integrated thermal valve ensures that the flap is activated thermally/automatically at an ambient temperature of 68°C.
