Ventilation flaps

Devices designed to facilitate natural ventilation in industrial and public buildings, installed in arched skylights or as individual units on the roof surface, which can also serve as roof access hatches.

The hatches are opened using a 230V electric actuator with a stroke length specified by the customer, or manually with the assistance of oil-pneumatic actuators. When using mechanical opening, it is possible to connect the actuators to a ventilation control unit that works in conjunction with a wind/rain sensor.

Door construction: raw aluminium or powder-coated in any colour from the RAL palette.
Filling: 10–25 mm thick multi-wall PC sheet
