They say you're not supposed to use a vacuum but I do.
Might just be a home user regassing his air conditioner. Air duster is usually just r410a
I'm not sure where you're getting your air duster but none of the stuff I've seen is R-410a. It's usually R-134a or R-152a. R-410a would be a much higher pressure. Trying to run an R-410a system on either of those refrigerants would not work out well.
Also even if they are full of whatever refrigerant you need, they aren't even close to pure enough to use in an AC system. I'm also not sure how you'd get it out of the can and into the system. You would need to make some sort of custom piercing tap or adapter for the can.
It's 152a, difluoroethane. It's never 410a or 134a.
Really? I think air duster is usually just pure CO2 (the ones without HFC at least)
I hope anyone who does these dusters realizes you can get whip it's on Amazon for like 20 bucks, then a cracker for a other 20, and then they won't be absolutely destroying themselves and their lungs. I also hate all the misinformation surrounding nitrous, fucking dentists use it for fucks sake, shits safe as long as you don't abuse it.
Pretty sure what these people are doing is the definition of abuse though.
The amount of people not understanding this is mental
