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 2440. 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).

Ventilation flaps arranged across a surface area (several individual or one continuous flap) can be operated by one drive unit on each side. On the rail mountings, LZG gear units are connected to the drive unit by means of a connecting shaft  (1 1/4“ tube – 2“ tube DIN 2440).

The racks move the pull-push rod along the rail mounting and the flap push bar are located on this rod. It is these push bar that actuate the flaps.

• Up to 40 flaps down the length of each rail mounting, depending on flaps weight.
• Up to 1500 Nm of drive power can be fed into the system.
• Load ratings of up to 16000 N per rack unit, and longer strokes or higher load ratings available on request.
• LZG gear units with various rack heights (Hzd).

Drive system for screening where the EWA power unit is mounted with a retaining plate clamped to the support. This creates an optimum installation position for adjusting the limit switch position. Suitable for screening systems with rigidly mounted screening fabric as well as for systems with grinding blocks.

• Up to 13000 m² of screening surface area with just one drive unit.
• Up to 300 grinding blocks with just one drive unit.
• Up to 1500 Nm of drive power can be fed into the system.

By mounting an EWA power drive on the gable, the resultant forces can be absorbed to an optimum extent. In addition, this creates a superlative installation position for adjusting the limit switch position.

• Surface areas of up to 3000 qm² can be screened with a single drive unit.
• 600 Nm input power can be directed into the system.

Single Roll Screening

• Single wrapped roll screen system for roof and partition walls.
• Space-saving by adapting drive shaft diameter to suit standard rolling tube.
• Max. ventilation height of 4 m with a rolling tube diameter of 50 mm, depending on type of fabric.
• Max. ventilation height of 5 m with a rolling tube diameter of 63 mm, depending on type of fabric.

Twin Roll Screening

• Double-rolled roller screen system for roof and partition walls.
• Space-saving through adapting drive shaft diameter to that of standard rolling tube.
• Central rolling tube for greater stability to wind pressure, reduced soiling of fabric and a combination of different types of fabric or sheeting.
