Electric actuators are used for automating opening vents for Natural and Smoke Ventilation. There are several types of actuators available, Chain, Linear or Folding Arm.
Chain Actuators are normally fitted to vertical windows. Heavy Duty Chain Actuators with a higher push/pull force (200-1000N) can also be fitted to rooflights and domes. Available in various opening stroke sizes (50-1200mm) and colours (White, Black, Silver) to suit the window.
Linear Actuators are normally used for heavy rooflights and domes where a greater force (200-2000N) is required to lift the vent. Available in various opening stroke sizes (180-1000mm).
Folding Arm Actuators are normally fitted to side hung windows or doors to give a 90° opening.
