Default Re: Small Workshop Air Compressor £67

Go for a reasonable size compressor and build a little shed outside for it.

Older, low speed belt drive compressors are a lot quieter than modern high speed ones which roar loud enough to scare the paint onto the car. A large displacement pump running low revs is a good recipe for long life, so you're more likely to find one in good condition. Look for something older, with a 4-pole 1400-ish rpm motor and then look at the pulley ratio to get an idea of the pump revs. Arranging sound deadening for the input air filter can help a lot.

Oil-less usually means trouble or amazingly expensive.
