I'd happily have another sip, ours will be 5ish years old now, runs morning and night running clusterflush on the milking parlour, and all the other farm inflating, blowing out, etc.
Apart from a couple belts, a pressure switch, and a service now and again it's been faultless.

I have run a ABAC fairly hard for 10 years now faultless, I have the 150 ltr model but have a second 300ltr tank to fill if doing big jobs, you wont go wrong with sip either, if your budget is big enough go for the biggest cfm you can that will fill the tank quicker and it will save your pump in the long run

+1 for ABAC. Got ours from Thorite, were a lot cheaper than anywhere else at the time. Buy the biggest you can afford.

We have a 3ph sip 25 years old this year. Doesnt get used massively but bloody good and durable. Full insurance inspections annually incl internal with camera no problems so far. Runs upto 11 bar. Cheers

While we’re vaguely on the subject what is needed to ensure a decent job of spray painting. Do they need an inline water filter I’m sure had been mentioned on here in the past?

I've got one from Shiremoor Compressors, 210 litre tank and SB26 pump on it. Must be 20yrs old, never been a problem.

I am not sure but someone will tell us, but dont forget to show us your attempts at spraying ?

You’d think @Zebbedee would keep us right

ABAB (and others I'm sure) do a 300l tank with 2 x 3hp single ph1 motors and compressors on it - leave the one powered up for day to day air and plug in the 2nd motor when you need more CFM.

You can buy a water trap regulator from lots of places , best to run everything off that to keep the water out of you tool’s as well , spraying depends on your gun but 30to 40 psi should do for gravity feed guns most tools run at 100psi but nut runners need everything you can give them

Thanks for all the advice guys. Just need to find the money now ?

If you have 3phase then I would buy one of those, the caravan utilizing nomadic travelers dont tend to nick them as not as easy to sell on and normally fairly large/heavy. Water traps you want certainly a couple, the modern ones are self draining once the pressure drops off in the line and not expensive.
I have never had much luck spraying with a single phase compressor, sure, it can be done but no substitute for CFM, you'll find some that are advertised as 13cfm dont actually produce that and your spraygun or air operated hand tool will be left gasping. We did think of linking 2 together to get the output but our old one was knackered so just bought a decent 2ph one instead

If you are going to paint or have a small blast pot, spend good money on a water separator, the £30 quid Sealey etc, ones do very little good this type of weather.

Hertz compressor are decent. Don’t bother messing around with piston machines. Get a screw or hydrovane.

Mattei mid range.
Compair tip end.
Hertz mid range.
Hpc premium
Abac are on the cheaper end.
Atlas topend

Steer clear of fiac and any of the lesser known models.

Out of interest, why do you say that.
Most of us dont need compressed air 10hrs a day, every day, with advent of decent 18v tools. How is a screw compressor better for intermittent use?

Screws give more air per given hp.

Take a 3hp screw. It’ll produce 14cfm and you’ll get 12cfm from it.

Take a 3hp piston machine. It’ll produce 14cfm but you’ll only get 9 from it because of losses.

Pistons are 40% onload 60% off or they overheat.

Noisy even the quieter ones.

Screws and vanes give a much better quality of air compared to piston machines. Better resale value as they are always wanted.

A piston might be less money but cost of ownership will be more due to their secondhand value.

 

[David.]

Thanks for that.

Yes and keep them topped up with oil!! Chap who did a lot of shot blasting have a vane compressor, sprung a leak and it was scrap as seized solid!
