Compression ratio:
- recommended: P2/P0 = 2.5
- maximum: P2/P0 = 6

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.
