take a look at a lot of compressor aftercooler units ,they are very much the same thing as intercoolers and oil coolers on cars [/quote]
Agreed, they [i]look[/i] very similar, but I’d like to see one pressure tested to over 10 bar before I’d use one. Car intercoolers rarely go more than 2-3 bar, so there’s a wide margin of difference. I’m not saying it wouldn’t work, but safety first and all that 😉
[quote=”ARTSPRAY” post=20723]i would also say that to configure copper pipe to achieve the same lengths and surface area as those involved with a average domestic radiator wouild be a plumbers nightmare especialy a double panel convector, [b]an old rad would also be financialy more viable[/b] ,it could also be dropped into a vat of cold water for added effect [/quote]
We’re agreed on that then.
[quote=”ARTSPRAY” post=20723]im pretty sure my son who is gas safe registered said [b]they should be capable of some 10 BAR plus[/b] ,however if fitted post diaphragm regulator you would not require any more than 4CFM for spraying purposes anyway ,as the fitting will be standard BSP and airline compatable it would be an easy enough excersize[/quote]
Awesome, it gets better.
I need a lot more than 4 CFM (the supernova needs ~12.5 :blink: ), but a domestic rad does sound like it will work well, as I said above. Especially now that I know they’ll take the pressure.

sorry my mistake that should have read 4BAR ,my bad lol
IE if you preregulate before the Rad down to a decent working pressure off a diphragm regulator then the rad need not be pressed hard pressure wise 4BAR is good enough for any gun and will give adequate CFM,i can imagine the internal bores of a domestic rad will allow a vaste CFM flow way above anything we would use in a bodyshop
heres an example of the tested ratings for one manufacturer as you will see they are rated at 10BAR working pressure and tested to 13BAR
Concept Compact Radiators
An innovative look all round with ultra-flat front surface.
The Concept features an ultra-smooth high gloss white front panel, top grille and side panels as standard. Each Concept radiator is finished in a two-stage high quality powder coated white gloss finish. The Concept is suitable for all low-pressure wet central heating systems, each radiator is tested on 13 bar with a working pressure of 10 bar. Its manufacture is certified to the Standards of DIN EN 9001:2008 and 14001:2004 and comes with a five-year guarantee. The heat outputs are tested to and conform to BS EN 442 Standards, they are also awarded the British Institutes Kite mark. The Concept features 4x 1/2″ tappings, suitable for connection to either single or two pipe systems. Each Concept is shrink-wrapped which can be removed once the radiator has been installed, this will reduce the risk of damage to the paintwork. The wrapping contains wall-mounting brackets, blanking plug and multi-directional air vent. Innovative looks all round, with ultra smooth appeal that will compliment any interior design. Combining high aesthetic appeal a maximum heat performance with optimum use of energy the Concept radiator is highly recommended. The Concept radiator is available in a wide range of sizes and outputs ranging from 305mm to 905mm high, 405mm to 3005mm length, wheather in single, double or triple panel sections.[quote=”ARTSPRAY” post=20725]

No worries. I thought we’d stepped into airbrush territory 😆My neighbour’s a central heating engineer. I’ll see if he’s got anything lying around :whistle:
yes i wondered what the fuck i was on about lol
And here’s the compressor wired and piped up:

The pipe work is semi-temporary, as we may be moving soon, so I’ve just set up a single outlet for my painting just now. If we manage to get the new building I’ll put in a larger diameter ring main system with several drops, but this does me fine for now.
I’ve had absolutely no water issues since this lot was fitted, so I’m happy :rock
