Thanks Joe, Gary & Ian.
No comments on the jet unit though, I was wondering if anyone had an opinion on the spec.
I used to have a little B&D unit delivering 1200 psi. It was a gift so can't complain, but really, why did they bother making such a thing?
1200 psi is close to useless, unless you just want to wet something. Sure, it washed off loose stuff, but so will a garden hose with a stray head at about 3 bar.
So I was determined to get something substantial. Electric washers at a decent pressure, all seem to be 3 phase 400V, so I went for a petrol driven compressor.
This says 200 bar, which is 2,800 psi, and I think commercial jet washer pressure is about 3,000 psi.
Does anyone have better knowledge?
