I agree, approximately 1 cubic foot of gas needs to be displaced to bring down to atmosphere. This project was not conceived by myself, and these are flaws I have already thought of. I need to discuss within my group. I have a feeling not too much consideration was made when conceiving this...

I agree completely. I think a blower as you have recommended would be the best course of action if the process just involved purging the room. It is pulling a vacuum to quickly with one of these blowers during depressurizing that concerns me. Right now I am putting this hold until I have a...

It is a service box on top of a digester, it is very small. 3 mbar is the gage pressure, the original request was to bring the room down to atmosphere, and then open a valve to allow air entry and place a CH4 monitor inside the room to measure methane content and continue to pump out the gas...

I am looking to use a PVC pump to push a flammable, explosive gas of minimal gage pressure (3 mbar) between two rooms. I chose PVC because it is non sparking, but I am concerned about static electricity build up. The pump will be used for 10 minutes at a time in a portable application, I am...

Budget, I am unsure. Obviously this PVC pump would be preferable to a custom made pump of a groundable, non sparking material. The OSHA report frightens me, especially when there is concern regarding friction. They give advice on grounding, but whether or not I could do this properly without...

Thanks again for the reply, I may be looking at a custom pump made from a non sparking material. However right now I am thinking about a pump similar to one shown in the link below: http://lifehacker.com/build-a-powerful-hand-pump-from-scratch-with-pvc-pipe-1186786117 Does anybody have any...

Thank you all for your replies. However I am beginning to think the only solution to this problem is a small manually operated pump simply because the size of the room to be purged is so small (less than 90 cubic foot). However it would have to be made entirely out of a non sparking material, so...

Hello I am in a bit of an engineering bind. I need to evacuate a small room of a flammable, explosive gas that is at a nominal pressure of 3 mbar by pushing it from room to another room (both at equal pressure). The environment is Class 1 Div 1. The rooms have valved piping that enable me to...
