Personally I'd go for http://www.transtools.co.uk/150022comp45ltr.htm
Its 3HP and has twin outlets.
Only £10 more than the 2HP eBay one (delivered) as delivery is free from Transtools over £50.

50 litre compressor tend to be useless, i had one in my work van, wouldnt blow the skin of a rice pudding! Changed it to a 100 litre one
Now that would even drive a 3/4" air gun
Hose's that tend to come with the cheap compressor are useless aswell, not big enough for impact wrenches ect. You want a minimum of
8mm(5/16" bore hose, 10mm(3/8) is ideal for everything but the bigest of air tools

Surely this is more down to the power of the motor?
The extra capacity will give you:
longer time to come up to pressure
longer to run before the motor cuts back in
Not had my SIP 2/50 run out of puff on me yet...althougu it you're looking at running intensive tools then a 3hp motor is desired.

depends what you intend to run, the CFM is what to look at, but many manufacturers dont list the details.
ideally you want minimum of 8CFM, which will drive air drills, sanders, and a small shotblast cabinet if you wanted, as well as the usual spray guns,
tyre inflators etc.
the one from transtools looks pretty good value.

Coincidentally i was on the phone this very morning trying to order that 'Valley' compressor that
'the_fbi' linked to. I thought it looked a good spec for the price. Should do most of what i want it for.
Funny/odd/annoying thing is i contacted them through Ebay and was quoted 25 for delivery so glad you pointed out free delivery through their own
website

Yea, can't quite work out how/why they are charging more through eBay, although clearly there are fees for eBay when there's not for their
own website.
The 100L vertical would be my weapon of choice, but I can't justify the extra cash just for more volume and a smaller footprint.

This one looks like a much better deal..

Its close to reserve now.

compressor
screwfix do a 2hp 50ltr for £100, I have a 3 hp 100ltr and only struggles when my 1/4" die grinder on full, spraying never found a problem.

100l struggling with 1/4" die grinder
Something amiss there then?? do you run it at full pressure? i used to turn mine down to about 90psi on the regulator and it ran great! That was on
the 50L one, 100L one used to wee it!

Probally, but used to last ages before the motor cut in!
The 50l one was shite, would just drive 1/2" impact gun, but wouldnt undo anything! Going to bigger hose made abit of difference but ports ect
were just too small!!
One thing to mention, if you indend to use the likes of impact guns, or owt that doesnt need the air reducing, put a coupling with a desent thouput
straight into the air tank!
Normally have a bung in one end with 1/2" female thread. Can get a pcl coupling with 1/2" male thread on it! With 10mm(3/8) hose you wont
have much trouble!

the CFM is what to look at,
The FAD is what to look for (free air delivery) as it is more relevant, usually it is about 2/3 of the CFM. Netto had the same spec compressor a
couple of weeks ago for £69.99.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

I realise this thread is a little old but I need to ask. I bought a 3hp 150ltr SIP compressor off of ebay. It will run a small sand blast gun but has
no puff for any tools. I was told that the commpressor isn't man enough for tools. Is this right? If not then what is the best thing to cange to
getting it working properly?

The pump
Is it belt driven or direct drive, oil or oilless. What tools do you want to run? I have a 3hp 50 litre which will run most things but die grinders
and cut off saws use masses of air so there's a lot of waiting time. Nailers, riveters and wrenches are no problem though. Spraying uses lower
pressure so the tank lasts longer. The tank size is only storage and shouldn't affect the working pressure, just the time it takes to fill the
tank and the running frequency of the pump. Do you run through a pressure regulator or straight from the tank, your reg could be faulty.

i was looking at one of these the other day, as my current compressor is a little inadequate - its a 7cfm/25L one, and maybe 1.5hp, trying to turn an
air cutoff and a die grinder! I havent researched enough to decide whether i should get one big one or another small one to pair up.

Its direct drive with oil, I want to run grinders, snips, riviters ect. I do run through a pressure regulator and through a 40ft length of hose (dont
know the dia off top of my head). Is it possible to run direct from the tank? Isn't that a bit dodgy?

Try a shorter length of hose you will get pressure drop due to length and small bore.

my 'dream hose' is one of those self winding ones, on a reel on the wall 1/2 inch bore ideally.
The hose makes a terrible difference to my tools, when you stop using them you can hear air moving into the hose for a second or so afterwards, as the
air catches up.

What I mean is do you run through the regulator on the tank outlet. I have put another connector on mine to run straight from the tank and I use a
trap/regulator at the end of the airline near whatever I'm doing. I have various sizes of hose and I don't notice any difference in
performance with any of them, the air runs ar 150psi to wherever the hose ends and the reg cuts it down from there. I don't have a "dream
hose" but find rubber ones are more manageable in lower temperatures and I also find tools ice up easily in the present conditions even with a
trap fitted. My longest hose is 20ft as I find it easier to move the compressor than drag a hose round whilst tripping over obstacles.

Yes I do run through the regulator direct from the tank. I will give it a go the way you suggest.
