It is not unusual that, during some applications the thrust generated by a pneumatic cylinder is not sufficient for the specific purpose it has been designed for.
In order to get over the problem, the working pressure may be increased to a maximum line pressure which normally is 6 – 7 bar; alternatively the problem is solved by an higher bore cylinder that suits the machine.
Three size pressure boosters, with pressure ratio of 2 – 1, have been designed to avoid these problems. This device is utilizing the compressed air of the circuit where it is installed.
