ELECTRIC WINDOW ACTUATORS
Electric actuators are used for automating opening vents for Natural and Smoke Ventilation. There are two types of actuators available, Chain and Linear. Chain actuators are used on vertical vents and small, lightweight rooflights. Linear actuators are used for heavy rooflights and domes where a greater force is required to lift the vents. Bother types are available in 24V dc and 230V ac and are available in a variety of opening sizes.
