Compression ratio:
 - recommended: P2/P0 = 2.5
 - maximum: P2/P0 = 4
Mechanical life: the number of cycles is inversely proportional to the increase of the compression ratio. For pulsation dampener applications, the nitrogen value must be from 60% to 80% of the working pressure also in relation with the type of pump and the working temperature.
