When I get my machine recommissioned, I will use it again, with the bigger compressor for large area clearance.

Just a footnote, I started off with a smaller pump, which was OK but not brilliant.
I just ordered thw ACO-328, which is also 80L, will see how it goes, thanks for the help. appreciates.
