Apeks First Stage Dst Xtx 50

Intermediate pressure surge - Dry chamber first stage In a traditional first stage, the increase in intermediate pressure (MP) is equal to the increase in ambient pressure (blue line). In the use of first stages with a medium pressure surpressure effect, there is an increase of MP (red line) higher than that of the ambient pressure. This increase compensates for the greater respiratory effort required by the increase in density of the air breathed in depth. Maximum limit CE Standards EN 250: 3.0
