Dual actuators (1 master, 1 slave).

  • Ideal for smart buildings; integrates with building and home automation systems
  • Low voltage DC motors are energy efficient
  • Multiple actuators may be linked for simultaneous operation of multiple windows
  • Push/Pull Force up to 700 N (158 lb) each actuator
  • Opening distance ranges from 501mm to 800mm approx.
  • UL Recognized
  • Applications

    • For automation of awning or hopper windows, skylights, or curtain wall vents.
    • For commercial, institutional and residential projects, including schools, universities, municipal buildings, offices, gymnasiums, homes, condos, and more.
