Just thought I'd post this here as I didn't see any definitive answers on this when researching.
I bought a ridge ryder ultimate air compressor from super cheap auto.
I bought a halkey roberts valve from ebay (3 types I just matched by looking at my hand pump).
a valve from an old mountain bike tyres and some lengths of pvc hose from bunnings which I fitted inisde each other and two campls one for each end.
bingo I now can inflate my red paddle board (10 6) fast enough. so far I've taken it to 23 psi which took 9.5 mins.
I did have to buy a separate pressure checker from super cheap auto as well.
much better than hand pumping.
the flow rate from the compressor is quoted as 160 l/min based upon that you need to get the big4wd compressors as all the car ones will take 20-30 mins to pump a SUP I think.
hope this helps someone
