Murphy AT-67207 specifications

Description

The AT-67207 is a completely reliable heavy duty device

developed specifically to automatically control engine

speed to meet system demand. Low current, high torque,

solid state switching and electronic clutch make it ideal for

all automatic and semiautomatic engine systems. Used

with the appropriate Murphy SWICHGAGE®, near constant

pressure, level and load can be maintained. Check with our

engineers for help with other applications where speed

control can improve your system.
