Curious as well. I read through the PA description and I see no mention of being able to fill SCBA tanks with it. Not saying it can’t but if it can You sure think they would mention that.
For $150 more I can get an Omega air charger. For a few hundred less there are multiple gun-tank only options. Not really sure where this fits in?
I've been using a Hill Mrs IV hand pump and have yet to jump into the less expensive compressor market due to durability issues. If the compressor is built with the same quality as the pump, and I have no reason to believe that it shouldn't, I'd be more prone to purchase the Hill compressor.
