Strange that! I had a LIDL airbrush compressor, with a disposable welding gas bottle to make a reservoir. I only used it to clean down the machine and shift any build up of chips. This has been since replaced with a small Jun-Air compressor, which is nice and quiet and it only cost me £20. It is old and needed a new pipe and a service, but it is a quality machine. Apparently these compressors are used in Banks as part of the security grill system and with the closure of Branches, they are becoming available.
