Screw in Respirator Cap Adapter 3m MSA AOSaftey

Last crawled date: 5 years, 9 months ago

I had an old AOSaftey respirator hanging out, but could not locate appropriate filters for it. It takes a screw in canister filter and appear to be similar to other types such as MSA. This is a an adapter that screws in and allows you to use more abundant 3m twist lock filters.
Looking for a screw in blanking plug that allows you to only use a single filter with this mask? Check here https://www.thingiverse.com/thing:4205498
