Hello
does any 1 offer this service? i dissembled my nvg and realized that I lost the purge, is this self do-able or needs a professional to purge it?

thanks

You don't really need to have it purged. Just make sure you don't get random shit inside and assemble it in a dry environment.

Once in while.

The most important thing is to do it in as low humidity environment as possible. You want 0% ideally, which is hard to get unless you can get access to a place with a really good HVAC system.

Purging isn't super important because it'll leak out of the scope in less than a year anyways. Odds are your 14 might have already lost it's nitrogen. Old school dudes used to put a small desiccant inside the unit to ensure any and all humidity will get taken out.

guys, i read online that people use duster gas to keep the moisture out via the purge port, is duster gas safe in the unit? since I have no idea where to get a small can of nitrogen, can i use Tetrafluoroethane or Difluoroethane?

thanks

Duster gas has other stuff inside it.
