I know, that there is possible to work with a hand-pump too – but trust me, the difference is HUGE. If You work with 2-3 bar, or special cases 5-6 bars, any solid contamination will be eliminated.
At first, You will need an oil-free compressor, if possible a silent one. After this, a filtering – there are cheep and expensive solutions. then a flexible hose, and of course a dust blow gun too. (Before I had a normal one – placed in the basement because of the 97 dB (!!!) noise.)
Here You see, what I use at the moment, this is as noisy as a washing machine:
Unfortunately the air gun is not a Swiss quality , so at first I had to disassemble and reassemble it.
