A small cheap air compressor is a real help when working on bikes for all sorts of jobs (tyres, air cleaners, painting, etc) so maybe keep a lookout for Aldi, Bunnings, Gasweld or even Supercheap specials. These will do most of what you will need and if the air cleaner is maintained they will last a long time. I've had mine for over 10 yrs and still going strong. https://www.bunnings.com.au/ozito-24l-1-5hp-oil-free-air-compressor_p6290553 There are plenty of different brands (and prices) around and maybe look to ebay/Gumtree for a second hand one. Good luck.
