Hey all,
Looking to setup a back purge system. Tried search the forum and there is not too much on the topic.

My first project will be to setup a back purge on my bringheli, can anyone give me the low down on whats desired?

1.) I know you need to VENT somewhere. Looking at the Sputnik and Anvil it looks like they dump from the Top of the Seat Tube, this is probably because Argon is heavier than Air and it will push it down and out but where? Do you want to push down and out to a vent in the BB or out the Chain Stays?

2.) I know I need a Dual Regulator/Flow Meter. Any recommendations?

Thanks in Advance - Todd
