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
