Continous system for roof ventilation

Ventilation flaps arranged in a line can be operated by a single drive unit. One or more racks are connected to the drive unit by a connecting shaft, a 1“ tube compliant with DIN EN 10255. The racks pivot with the flap.

• Up to 600 Nm of drive power can be fed into the system.
• Strokes of up to 1800 mm and loadings of up to 2500 N per continous rack, with longer strokes or higher loads available on request.
• Integrated swivel bearing with the ZSG range, with gear units mounted directly to the roof construction. The connecting shaft is guided through the gear unit.
• External swivel bearing on the AZD / EZD ranges.

Alternatively with scissor gear unit SGS. For use when rack cannot be located in room, and for low load ratings (e.g. conservatories).
