MAN / MA-5P

The MAN is a 2 Position, power-open, power-close actuator. Used on old-style, standard opposed blade dampers. The MA-5P is a 5 Position, power open, power close actuator used with old-style, standard opposed blade dampers. MAN and MA-5P actuators are only interchangeable with other MAN or MA-5P units.
