This probably in the wrong section

.
Anyway can peeps give their views on this compressor.(in the sunday papers)
http://www.wolf-online.co.uk/acatalog/i ... 619%2ehtml
Priced at £99.99 plus p&p(£10)
Like It just for occansional use, powering air tools, I'd like it to do small spraying if its capable.
Thanks

It would be fine for smaller spraying jobs (wings etc), but spraying an entire car would be outwith it's capabilities (unless you did a section at a time - waiting till it got up to pressure again). It would also struggle with a DA sander. But if you know it's limitations it would be ok at the price.
Compare it for specification with what's in Machine Mart etc.

As P O said, fine for small spraying but look at your air tools or any you are considering buying cos most need quite a chunck of air to run.
If all you want is a tyre inflator or a small sprayer no probs but Sanders, grinders or some drills may push it to far.
I've just looked at Machine Mart and most tools (Drills, Impact wrenches and some grinders) appear to be about 4cu Feet of air a min.

There's a relatively cheap compressor coming up next week at Aldi!! Up to now I have just used a frig compressor - yes, the little black thing from the back of a domestic frig. This is connected to a large Calor gas bottle as a receiver - with a suitable relief valve of course - and will pump it up to 200 psi. I keep it full of air all the time - and it's fine for blowing up tyres and spraying one panel at a time.

BMC, Oh, I like that! I'd love to have a rummage round your garage.

Hands off!! It works. In fact - if I 'forget' it's running - it blows the rubber hose connection off at about 200 psi (amazing scary noise!) - but i do have a proper relief valve on there anyway - and a reducer set with filters for the outlet connections to tyre connection and spray gun. ALDI also have a nut-runner and wheel nut gun coming up with the compressor!

That looks a really good price at aldi, think i'll pop along to aldi on Thurs and take a look.
Sorry if my maths is not very good but it says its 2.5Hp and its 1500watts
Doesnt 1Hp=748watts so 2.5hp=1870watts.
Maybe its a preformance realated figure.
Thanks or the tip BMC

BMC you scare me. I wonder what the pressure rating for a calor gas cylinder is. And I'd worry a lot about hose failure at that pressure. If it was a commercial kit it would have had a hydaulic test. There was a case last year of a water fire extinquisher exploding at well under 200psi and it caused a lot of damage.
I had a similar set up, (but I wouldn't recommend it now due to worries about venting the fridge gas and wrecking the ozone layer) with a proper air reciever. I kept it down to 60 psi.
I should mention that I used to be a plant and process engineer and have seen the devastion caused by fairly small failures.

The Calor cylinders are designed for way above that pressure - I agree - it would need test and annual inspection in a commercial environment. I only use frig compressors where the gas has already leaked away (!) - so no more harm from 're-cycling' it. I am a Plant Facilities Manager (just one of my hats). Anyone doing this should be aware of what they are doing - and they do it at their own risk - I merely recount what I have done.

For spraying as said above 4-6cfm is required, for decent air tools like DA's sanders etc you need 13-15cfm and a constant pressure ie the larger the reciever the better.

Exactly - large receiver is the way to go - it can re-fill while you pause for a cuppa and a breath of fresh air - or to review the damage you have done!

200 psi is enough for the flying scotsman to pull a 12 coach train.

Aye - but Brixton - that was expanding superheated STEAM - not the same as boring old air!!
So - how many of you grabbed a compressor at ALDI this morning ? My dear wife queued up from just after 8am to be second in the long line !!

Did she get one?

Of course! And an Impact Gun - and a Nut Runner to go with it! By 9am there was a queue down the car park - and a mad scramble to get through the doors of the shop.

No aldi near me

Although I've got some cracking TUV marked tools from Lidl as well as all sorts of lubricants, chisels and a storage box. They sometimes have a very cheap 15w40 I use for my brothers BMW, lawnmowers etc.

bmcecosse idea of a compressor made me really scared at the thought of that idea

for the cost of £200 for a decent compressor thats is suitable for most air tools i wouldn't like to take my chances

The old Frig compressor has stood me very well for many years ! Sprayed my Traveller with it - panel by panel of course. I am an engineer - and i know what I'm doing - no 'chances' were taken. If you don't know - don't do it! But it's all behind me now anyway - fine compressor from Aldi with full kit of bits to go with it - all for £60 !! And a 3 year warranty too.
