It's easy, just make it so that the pneumatic system needs to do no work. That means, don't put any cylinders in it. Then it will maintain pressure.
But if you want the system to move something on the robot, then the air pressure in the storage tanks will drop, and you'll need to refill them with the compressor.
What pneumatics does is use a motor (the compressor) to do work remotely (the cylinder) by using air flow.
If you don't let the air out of the other end of the cylinder then there will be no pressure difference in the cylinder, so the piston won't be able to exert any force.
