For less than an hour a week one of the circa £100 ones will do the job.

Most of them look as if they have come out of the same factory
As you suggest cfm is the output
50 litre / 100 litre is effectivly the buffer so bigger is probably better

Most will need some box ticking at some point or other, so I’d go cheap cheap and Chuck it away at two years old. That is assuming it won’t need testing for two years from new.

I think anything over 24L airtank capacity may need periodic testing.
I sold a 150L SIP compressor for this reason and bought a 24L Hyundai 'silent' one which while not as good it does the job and is indeed a lot quieter. It's also easily portable if that's a factor.

as above if you keep it under 25 litres it doesn't need to be tested , just make sure the pump is a reasonable size
nothing worse than waiting 5 minutes for it to get to pressure on a big tank to top up a super single
have a big and a small and the big one gets used less and less

I have an SGS one - had a problem with it and the aftersales efforts made me think of words like rude and unhelpful - I`d be very unlikely to deal with them again. Machine Mart do VERY similar machines (from same factory??) and they seemed a lot more helpful.
If you want to take the compressor to a tyre with a tank of air I`d say get at least 100litre tank.

I was told it’s less than100litre that don’t need testing.NFU assessor came here one day and pretty much condemned all my ladders saying they needed to be trade ones rather than DIY ones.But the compressor was ok even tho it was old cos it’s 50litre.

Get the highest CFM rated compressor you can, it's litres per miniature at delivery that counts (That's often tied with larger tank though as well). Nice little guide below

https://www.sgs-engineering.com/hel...buying-guide-which-compressor-should-i-order/

Generally anything below 100 litres is junk for farm/industrial applications IMO, you want to blow a tyre up in seconds or few minutes, not standing there for half the day.

Handy to have a guide BUT...

It’s the combination of pressure and volume that make a compressed air tank liable for periodic (formal) inspection under the regulations.

Take the max pressure and multiply that by the volume, and provided the number of bar-litres is under 250, it’s grand.
So:
  • 100 litres at 2.5 bar
  • 50 litres at 5 bar
  • 25 litres at 10 bar
Etc. is the limit.

Hitachi makes a very nice smaller "twin hot dog" compressor, that is quiet enough, will last and be under the pressure x volume limits. It will be slow to air up high pressure tires like 120PSI, and slow to air up a tractor tire from empty, but fine for adding a few PSI etc.

I'll just add that I had SGS compressor go for warranty repair. Took three weeks for me to persuade them it was in fact broken. Then two weeks for repair to be done they emailed to say it was fixed. Then another three weeks for them to return it. They are Hard work

They are indeed. Would never deal with them again, no matter how good the deal.

Very pleased to see it isn`t just me that thinks they`re a shower of :poop: ...!
Really short sighted of them as a bit of good service goes a long way in terms of repeat business.
Had a manifold break on my compressor when I "over-tightened" a fitting - they just blamed me for being too rough. The metal was actually the most like plastic I`ve ever come across (apart from the plastic "metal" that Chinese made toys are constructed of !!) They said the thread on the manifold was tapered - it certainly soon cracked. Maybe a note in the instructions to that effect would have been helpful.
Just out of interest I did ring Machine Mart to talk through the same problem and their attitude was very different....👍

Sorry, I should have looked first. It doesn't seem Hitachi sells air compressors in the UK. and their power tools are now Hikoki (Hitachi Koki). This is the one I'm talking about, but it seems the Metabo might just be the same one?

I guess the Metabo stickers on the Hitachi Walmart listing should have tipped me off.
