Re: Using Canned Air For Removing Dust
Be aware that canned air isn't. Well, it is certainly canned but not air.
There are 3 common varieties.
- HFC 134a/143a/152a which are potent or very potent greenhouse gases and are toxic/corrosive when burnt (but not too easily fammable).
- Lighter gas (propane/butane) which is obviously flammable but otherwise not too problematic.
- 1234yf tetrafuorpropene still toxic/corrosive when burnt but not easily flammable and not a strong greenhouse gas.
So real compressed air is probably better.
