Compressors can be expensive things to pick up, and I imagine pretty expensive to maintain... But just how much? It's something we're thinking about as a club but would like to understand the overheads... New, I can see options that look good for a club (smallish and semi-transportable) for around £5k https://www.mikesdivestore.com/prod...iBICKODvU8_je1fbPTf9ahq9dnnTmJBAaAmG1EALw_wcB Second hand, the cost could be half that for something which (on the face of it) looks decent: https://m.ebay.co.uk/itm/HAMWORTHY-...vr_id=1476634001838&_mwBanner=1&ul_noapp=true What would the annual upkeep on these cost, and would the second hand one cost so much for an initial service that you may as well start new? Ebay also offers a load of flimsy looking Chinese things which apparently work to 300bar for under £500. They seem to lack all of the filters etc. you would normally expect on a breathing air compressor. Presumably these are outright dangerous??
