CLEARING UP ON THE COMPRESSION
RATIO When talking about the compression of a pneumatic pump
(75:1), 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 75:1:
air pressure introduced at 1 bar will output fluid at about 1 x
75 = 75 bars;
air pressure introduced at 6 bar will output fluid at about 6 x
75 = 450 bars.
