Default 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.
