The EF actuator utilizes rugged components in a pressure cast aluminum housing for added strength and reliability. It offers a high torque output of 270 in-lbs and a NEMA 4 option to meet tough environmental conditions found in many HVAC applications. The EF actuator was developed to satisfy high torque applications with a single actuator. The EF can take the place of two classic AF actuators in a piggy-back mounted application; simplifying wiring and mounting requirements while reducing material and installation costs. The NEMA 4 protection feature allows complete access to change the direction of rotation and allows locking or manually overriding the actuator. The EF provides a cost effective and flexible solution that will deliver years of dependable performance over a wide range of operating conditions.
