What is an actuator on a window?
What is an actuator on a window?
A window actuator is a device installed on a window that allows it to open and close automatically, eliminating the need for manual operation. They are ideal for hard-to-reach windows and rooflights, multiple windows that need to operate simultaneously, or buildings aiming to take advantage of automated windows and enhanced natural ventilation.
What are the key types of window actuators?
What are the key types of window actuators?
- Electric Chain Actuator: Pushes/pulls the window using a chain; good for medium-sized windows; smooth and quiet.
- Linear/Spindle Actuator: Uses a screw-like spindle to extend/retract; precise and robust; supports heavier windows.
- Folding Arm Actuator: Uses a hinged arm to swing the window open; allows wide openings; good for heavy or outward-opening windows.
What to consider when choosing a window actuator?
What to consider when choosing a window actuator?
When selecting a window actuator, keep the following in mind:
