It's possible technoloy has improved in that time though, but as oil freecompressors are separately listed, I have my doubts...Fair enough, I'm not an expert. But I can say these are designed without facility for them on the compressor side now and mine has been running very happily like this for 12 months, and I know of another that's at least three years old personally - and I have no doubt they'll serve me and others well for light use for many many years.I'm sure that for driving tools they're fine and should last years - I was meaning that for use to blow the dust off a PC they may be somewhat sub optimal and they'll be blowing air and oil (and water vapour) too.What oil?
The oil that you use to lubricate the bearings, pistons, etc. it gets into the system and ends up as a very fine mist in the air that you then blow over your PC.
It's probably not noticable, but keep on blowing air over the same thing and you'll eventually see a build up of oil - that will attract dust and who knows what else.
Personally I'd never let a compressor like that anywhere near a PC/Laptop.I'm really surprised at your negativity, Gordon.
I don't want my PCs covered in oil. It's as simple as that. If you use an oil lubricated compressor you will be putting oil out with the air. (unless your taking precautions to filter it out)
Modern PCB's are very robust and I doubt very much there is anything more than the tiniest theoretical risk of damage beyond blowing mountings and wires loose by being heavy handed, and this technique is very widely used in the refurb world. Personally I don't like working on machines that are filthy if it's a pleasant two minute job to sparkle them up.
What I have a Dyson for.
But hey, each to their own. I stand by my recommendation as somebody who also has a fair bit of experience :)
Fine.I've worked in a machine shop. I've also worked in a dive shop (and on dive boats) where the compressors are very different to machine shop ones. I've used all sort of compressors and I'd not use one with oil it in to blow the dust out of a PC.
