Compressor.. big boy! Single phase and airfed..

[Twosugars]

nice

If you have the space, I would keep the two and join them.
Handy to have a spare if one dies and generally one will kick in before the other which means less of a spike on startup if you are limited on your supply.
I prefer the cast-iron pumps, they do them in a 2 (V) or 3 (W) and they are pretty well regarded.

I've got a 3 cyl AIE one coupled with an old Sealey with an Italian pump. Both rated about the same @ 10 CFM FAD - the difference is the Sealey screams its guts out to do it (I keep meaning to downrate it and make it a bit slower).
I run them both from a 32A supply via 16A MCBs and couple them in to the airline with ball valves so they can be isolated if necessary. They have different cut in and cut out pressures so it staggers out the load on the supply.
Both are small enough I can get them under a workbench as well, so I don't lose too much space.

I feed them into cooling matrix made from copper, and then into hardline around the workshop, 22mm ring with 13mm drops to a filter/reg and drain. Never seem to get any water out of the drains and the air is nice and dry.

I only run both if I need the air for masks or the blaster, most of the time I just run one for general use, which cuts down on the noise. Either compressor can fill the tank of the other, so you can still make use of the tank capacity even if it isn't running.

Works for me anyway and it would save buying a huge compressor if you already have them.

This sounds like a great option.. I am lending one of the compressors so I still may purchase another smaller one.. il have to look into the cfm of my eco air but it managed to paint a full mustang ok..

Il have a look on the forum to see if there are any diagrams as I am not intirely confident of plunking them in I know that sounds rediculous. I also am unsure how to make sure the pressure switches kick in at different times but completely understand the logic behind it, thanks again

This is a great machine. Had mine for about 10 years now and wouldn't be without it. They're not cheap new but do pop up on the secondhand market occasionally.

Have you guys got the model number of this particular Clarke? I’m definately considering it if it will run both gun and air fed..

I don't know the model no name on it its just similar or the same as the machine mart one. don't know about the fan have you details of it

See post #14. Adjusting the cut-out pressure is a simple screw adjustment.

There’s two that are quite similar .. one is rated 28cfm 30a supply and one is 36cfn 45a.. it’s a choice between the two at the moment ..

 

[brightspark]

mines about 28cfm and has 2 three hp motors fitted it would depend on your air requirements and your power supply

Think I’m going to join the two now guys.. been reading the helpful guide on here and it would make sense.. I’m sure two 14cfm 150s will power my mask and gun (may swap to my Devilbiss pro rated at 10cfm with t1 and t110 cap).

Found this great website for fittings thought I’d share..

Thank you for your input it’s been very helpful indeed

This is mine:



To be picky, mine is actually the SE29D270.

What size power supple do you have available?

 

[Twosugars]

Aha lovely stuff! I have 30amp available at the moment.. does that power a gun and mask? That’s my main concern..

Assuming you mean my compressor, easily. I have done 2 pack with a forced air breatning mask and it doesn't even run constantly. Remember, your spray gun isn't drawing air constantly and whilst your mask is, there will still be plenty of recovery time.

And clearly with only a 30A power supply, the 36cfm machine is out of the question.

Also remember to bear in mind other loads such as light, heat, radio etc.

I have a 50A supply to my shed but also have three 1500w electric space heaters and a 1500w water heater. Allowing around 7A each for those, and a couple of amps for lighting (all now LED) I do risk the power tripping off if I'm unlucky enough to have everything come on at once! However, it is only a small risk and I'm comfortable with it suddenly going dark! At least until the emergency lighting comes on.

Thank you for your reply I think your compressor will be more than ample then formmy needs il look into them,

I am concerned about the supply I’m sure there’s more than one 30amp but that’s what is visible right now I have a sparky visiting next week.

For me air fed is essential so even if I run a less efficient fan I will have a good level of protection il just have to allow a longer clearance time before re entry.. the main thing being the booth is sealed to stop anything escaping into the workshop. Luckily it’s situated in old farm house buildings with agricultural painting rights with no one around to be effected which gives me some peace of mind.

Thanks again you’ve put my mind at rest Just got to weight up wether il run my two or make the purchase ..
