Jules, Don't do it!
Last year I bought a 2HP compressor very similar to the 8/44 unit, with an integral motor-compressor. Worst bl**dy thing I ever bought:-
The noise is deafening, mostly because the whole lot is rotating at 2,800 rpm;
The regulator was great until the thread in the regulator control-knob stripped - whoops, no pressure at the delivery;
It cuts-in when you least expect it - like three o'clock-in-the-morning - which doesn't please the neighbours too well. OK, that could be avoided by unplugging it from the mains.
I've since bought a very much quieter belt-driven jobbie but with it's only 1/4 HP motor it is v..e..r..y slow to build up to pressure and, when spraying, it cannot keep up with demand. Having said that, it keeps up with my staple gun and also just about keeps up with air-testing my steam engine.
I guess the best bet would be a belt drive from a 1 or 2 HP motor. But that will be expensive to buy.
