Performance features
- For opening and closing skylights for ventilation and smoke extraction applications
- System consisting of drive unit and skylight‑specific installation set
- With integrated BSY+ motor and synchronised electronics controlled via microprocessor
- Service life inspected with at least 20000 opening cycles for ventilation and an additional 1000 opening cycles for smoke extraction in accordance with EN 12101‑2
- Optimal aerodynamic values by quick opening to 172°
- Power transmission structurally optimised, therefore minimum strain on ventilator frame and hinges
- High type of protection for drive unit; can therefore also be used under difficult ambient conditions
- Quick installation and easy handling thanks to modules pre‑installed at the factory
- Installation sets available for many skylights
