Rotary Actuators

MS81 Two-Position Actuator

MS81 Two-Position Actuators are spring return direct coupled actuators (DCA) with an integral junction box for on/ off damper control.

Overview

MS81 Two-Position Actuators are spring return direct coupled actuators (DCA) with an integral junction box for on/ off damper control. The actuator accepts an on/off signal from a single-pole, single-throw controller. Reversible mounting allows actuator to be used for either clockwise or counter clockwise spring rotation. Designed to operate reliably in smoke control systems.
