The COMPACT actuator is a quarter-turn rack & pinion pneumatic actuator that doubles the torque of standard pneumatic actuators. The superior performance is achieved by Habonim’s patented four piston design, which generates torque around a centrally located piston. This translates into double the power for the same size actuator or half the size for the same amount of power.
