I got a 25L wolf air compressor from Aldi's a few years back just for blowing out the hoover filters as peed of trapsing round me dads all the time to use workshop one, must say it's ace, very quiet compared with my 25L SIP, SIP now about 15-17 years old, never once changed the oil always drain and it has never missed a beat, it was cheaper not to service it and just buy a new one if it lasted say 5 years so been lucky.
Aldi advertise these things but never these days seem to have them/stuff/offers in my local one, Thetford, Norfolk.
