MEMBRANE AIR BREATHER WITH M18x1.5 THREAD [0316]
The air breather is used to convert a double-acting cylinder into a single-acting cylinder.
To convert a double-acting cylinder into a single-acting cylinder, simply select a breather with the appropriate thread and screw it in into one of the two hydraulic outputs on the actuator.
Usually it is the upper exit, from the piston rod side.
The actuator converted in this way will work as a single-sided actuator.
