Compressed air can-whats the best brand?

When using compressed air you might want to hold any fans in case the air tries to spin the fan faster than it prefers to spin

I guess that was meant as a joke?!

The problem with ordinary compressors is if you use them with an air-blower gun attachment, you may get contaminants such as oil/grease coming through. Industrial compressors/air blowers have a special filter to prevent contaminants damaging the equipment you are cleaning. This is more critical for clean manufacturing processes etc.

You may be able to use a standard compressor with an air-blower gun attachment in a mechanical workshop or vehicle garage where small contaminants aren't very critical. It's not recommended for delicate electronics such as computers etc.

Yes you can get oil/grease coming out, last job i had there were 1 of these for us to use and some ejit broke so it was fixed and some time later oil was coming out although not constantly but in small drops.

It does in conjunction with a brush to loosen the dust. In fact compressed air won't remove all the dust on its own.

The brush will not reach all the way inside long narrow folds of a heatsink. Neither will a vacuum cleaner suck out the dust. However, the small tube on some air duster cannisters will reach inside the folds of a heatsink like this one:

I use dust off - bought from Costco, which was heaps cheaper, but very effective, than other places we looked.

Sorry can't remember the price.

I believe Dust-off is a Falcon product. See my post above. They use a bitterant which is horrible to work with!

I use a small compressor as in post #6 - it's an oil free one though and I use it for blowing the carp out of everything - never had any problems so far. Also use for pumping up the tyres on the car, motorbike and wheelbarrow. Bought for £50 9 years ago and would buy another any day - often seen on offer in Aldi. Get one, don't mess around with expensive aerosols:)

So there is a possiblity of cross-contamination from dirt/grease on those tyre valves entering the compressor pipes/fittings.

Also with any compressor, as it ages, there is a possibility of tiny pieces of metal (due to internal mechanical wear/break-down) being emitted with the air.

Hence, why it is recommended to use compressed air cannisters for delicate cleaning of electronics/computer parts. These cannisters do not contain any other contaminants.
