Could a RMSH-2 get saturated with N2 if it stays opened by one hour?

• Hi gasuarez01,

the big universal trap contains adsorbents for water, oxygen and hydrocarbons. If left open for an hour the moisture in the ambient air will saturate some of moisture trap material and the oxygen trap materials can be quite saturated (maybe not fully). If there is no flow the saturation is dependent on the diffusion of ambient air into the trap.

Regards,

Norbert
