CLEARING UP ON THE COMPRESSION
RATIO When talking about the compression of a pneumatic pump
(50:1), this means the direct ratio which exists between
the pressure of the compressed air introduced, and the pressure
leaving the pump. An example:
Take a pump with a compression ratio of 50:1:
air pressure introduced at 1 bar will output fluid at about 1 x
50 = 50 bars;
air pressure introduced at 6 bar will output fluid at about 6 x
50 = 300 bars.
