I have a friend who uses one of the three motor Clarke Shhh compressors in his garage at home for sand blasting and another who has a hydrovane compressor for his glassblowing studio. Both of them are quiet and high volume output. At about £1,500 and £3,000 each these would do the job nicely . I on the other hand have ordered an 80L pond air pump for £35 as I feel that the 35L one at £19 was underpowered (but it does the job OK-ish). I have got an old Clarke Tiger with a 50L tank, which has served me well for spraying, air tools and nozzle blast cleaning, but run it continuously for 10 mins and it starts to smell of hot oil and frying electrics, but there again I am at an age where the same happens to me .
Cheers - Rob
