Title: Workshop compressor?
Post by: VladTepes on Saturday, 28 March 2020, 01:24 PM
Looking to buy one but on a real budget so prefer decent 2nd hand to crappy new.

Happy to do some repair /restoration if needed assuming a brand parts are available for.

I'm looking for a single phase compressor adequate to run a spray gun. And general workshop tools.

Would appreciate if people could tell me what I should be looking out for feature wise, what brands to look for to buy and to avoid. Also an idea of what sort of $ is expect to be paying.

If it's at all possible I'd prefer in the 200 buck or so budget maybe a bit more.

If possible.

Advice welcome.

Cheers

Yep bigger the better. My workshop compressor is too small, tools run out of grunt and compressor runs too much and gets a bit hot, that will put a lot of condensation through your air lines.
You need a water trap if you are spraying and in line as far as possible from the compressor so the air has cooled before it gets to the trap.

For home, 180 - 200 L/min free air delivery isn't too bad, but as they rightly say, the bigger the better. 

I have a direct drive 180 L/m, max 130psi compressor, fine for my uses.  Run air rattle gun to 360nm torque, lots of tyres to inflate & check here too & a small sand blaster, which works well after I modified the pickup to something that actually works.

Bigger is better. My compressor makes 230 liters (8 cfm) @ 6 bar (87 psi) and it's too small.

I have a Campbell Hausfeld 5 HP 20 Gallon 6.6 @ 40 psi or 5.8 @ 90 PSI 135 PSI Max - does everything I need! Got it second hand a while back for $250. I put the hoses on reels with a clutch so very easy to run out and retract.  They are about $600 now - never had a problem with it. Also have a couple of smaller ones for tires etc.

This is mine, does everything  i need,  rattle gun etc. 

Haven't tried spray gun yet, but should be fine.

They come on sale at SCA quite a bit complete with tools and hoses.

My neighbour across the road is a mechanic, he uses the same unit all the time,  no issues.

Warranty is great, i had the small bore hose for the tyre gauge fail after a year, SCA replaced it no questions asked.

Don't know much about ozzy lectrickery, but in UK, MOST properties are on 240v single phase, which equates to 13amps  per plug, 1 hp pulls 4 amps, so a 3hp compressor will draw 12a just enough for our 13amp socket.  3hp will run a 14cfm compressor.
More than 3 hp usually requires 3 phase.
I use a V twin, 14cfm pump driven by a 3hp motor, & a couple of 100 ltr tanks connected together, this runs all my air requirements fine.

Ozzy lectrickery is about the same as UK, I do similar to Lawrie, run a twin compressor and old single in parallel so when the twin struggles the single kicks in. Both can run on a 20amp current it's only if both try to start together the inrush current may be too large.
