On large windows up to four WMU 836 actuators work together on the same window without an external synchronisation module, cutting hardware and wiring cost.
Stroke options up to 1000mm open large windows wide for effective natural ventilation, with 3000N locking force holding them secure when closed.
An onboard micro controller provides electronic limit and safety stops, with position feedback and three speeds when paired with a MotorLink control unit.
Single, double, triple, and quad actuator options run up to four units on one window with synchronisation handled onboard.
Three speeds and position feedback with a MotorLink control unit, available on request.
Electronic limit and safety stops plus electronic disconnection to avoid overload.
Controlled, quiet closing protects seals and hardware over thousands of cycles.
Supplied with chain fixing bracket, upper bracket connecting pack, fitting and drilling template, safety plate, and installation guide.
Long strokes and multi-actuator synchronisation suit wide or heavy windows in commercial facades.
400mm and 600mm strokes for general window types. 800mm and 1000mm strokes for bottom-hung windows only.
Automated daily ventilation in commercial, educational, and residential buildings. Not for smoke ventilation. If you require smoke control products or advice, call us.
Up to four actuators can be mounted on the same window with no need for an external synchronisation module. Available in single, double, triple, and quad options.
400mm, 600mm, 800mm, and 1000mm stroke options cover everything from standard vents to large facade windows.
Position feedback and three speeds with a MotorLink control unit, available on request.
Slows the chain at the end of travel for quiet, controlled closing that reduces wear on window seals and hardware.
We have a team of ventilation specialists on hand to help guide you towards selecting the right actuator for your project.
