Aprimatic ST450 For Flat Roof Vent Control

Linear style actuators such as the Aprimatic ST450 or UCS Max Actuator are favoured for flat roof vents as they tend to have a higher IP rating to help protect from rain and dust. Linear actuators are also typically more powerful than chain actuators making them better suited for these heavier types of windows that require more force to lift.
