Compressor advise

I'm after a compressor for hobby use only, I need it to spray run air tools and a DA sander would this one be man enough?50 Litre Air Compressor - 9.6CFM, 2.5HP, 50L | eBay
Or should I get one with bigger tank

Should be fine for spraying, you'd want an oil/water filter on it though. Check what cfm requirement your air tools use. If it's less that 9.6 then it'll work. Better if compressor is 30% more cfm output or else it'll be constantly running. But if it's only hobby use then that shouldn't matter.

Thanks. Any other thoughts anyone

Rhyas 6 8 24 50 Litre VTwin V Twin Air Compressor + FREE Kit | eBay

My sister bought me this for my birthday, ive just sprayed my landy with it no problems.
Higher cfm output than the one you have posted.

Won't be up to running a DA matey, will be ok for an air gun (impact gun) would struggle with an air ratchet, would probably struggle with spray gun as well depending on what type and size gun you've got and how good you are at spraying.

My 100l with 3hp motor /14cfms copes with the da for 10 minutes or so before needing to charge.

My 24litre 2.5hp 9 cfm barely makes it Turn for more than a few seconds .

In tandem they run it infinately.

So I would need something like this

Also have just done and might still have some 3hp 14cfms 50ltr compressors.

These are bigger higher spec than there normal small ones.

I know they still have the air tools in we I picked up shopping the Friday.

Better but will still struggle with a DA, DA's use a huge amount of air and as there generally running for long periods of time smaller compressors will struggle to keep up.

Have you looked at electric DA's? more expensive but probably cheaper in the long run as running a compressor for long periods will use quite a bit of electricary.

I have an electric one, as da,s seem to use most air I will use the electric one. The 90 ltr 3hp compressor should be ok for everything else?

The HP is not important, the CFM is, the second one you looked at should be ok the only thing you need to check is the CFM of the spray gun you've got.

A spray gun is a bit like an open air line but does depend on how good you are at spraying, a good sprayer will use air quicker as they tend not to stop very often also are you doing full resprays or just panel repairs?

When i used to paint i has a 14 CFM pump on a 200ltr tank which worked fine a 90 ltr tank is quite small.

I have got a 160ltr industrial compressor, unfortunately it draws 30amp on start up and my new workshop only has 16amp power supply, I will use the compressor to spray my series but it will be panel by panel as it will be stripped down so I think the 90ltr should cope.

14cfm and 90ltr tank should be fine for that matey

I had a 50litre tank, wasn't big enough to work my tools. Bought a Clarke 150litre, can do anything.

Vinnie110 · Mar 23, 2015

I'm sure I've heard a few people have picked up a dead compressor on eBay for the tank. Then had two tanks getting filled. Not sure just how they have plumbed it all in.

Was considering that option if the new one couldn't handle it. Thought about using an old Calor gas bottle, obviously cleared of all gas residue. Shouldn't be difficult to plumb.

Belt drive ones are a shed load quieter than the direct drives....the bigger the CFM for your money the better.
