Gas dusters have crap pressure and crap flow.
A 7-10 bar compressor is pressurising gas to 100-150psi and you can damage components if you're allowing too much gas at too high a pressure out.
Computer fans don't even appear on the same scale of pressure.
Also, if you use a compressor without a filter it can blast out hard particles with the air at very high speed.
i never thought of that... i shall have to be extra careful next time
