Ive currently got a little Air compressor, only about 10 litres i think, but its just not big enough and if i use the air grinder i have it just slows down and doesnt do much. Im wanting more air tools but dont see any point while this compressor sucks.

So anyone got any recommendations? im looking to run air tools and use for spraying. I dont want to go too OTT as i only have a single garage and space is a premium.

good deals new or anyone shifting second hand considered as student budget confining!

you will need a minimum of a 50litre receiver and upward of 9cfm and 115 psi.

I am running 2 compressors 7cfm in tandem and can still outrun them with power tools and a spray gun

I have a similar problem and decided to go down the small compressor, big receiver route, using 47Kg propane cylinders. These will be mounted outside the garage at the back.
I can have a coffee while they fill.

You just missed one that a mate was selling pretty locally to you!!

Thats the sort of thing you want ideally for the sort of use you mention with as mentioned a min 50L tank and plenty of power in the motor.

damn it!

any brands worth avoiding?

ive seen one on fleabay for 120 delivered, but its unbranded.

Practical classics did a test recently and their had a SIP at around £200 with a 3HP motor and big tank which came out pretty well/

Done the adding propane cylinder thing, that gives a little more the problem is how fast your emptying them, I am running a 1.5 and a 2 hp compressor both rated around 7 cfm and can run them dry in minutes even with the compressors bothe running.

Ps the propane cylinders will have a residue in them which will enter the air so cause problems when painting etc

I have a 50ltr 3hp direct drive compressor which gives 150psi 14cfm, about 9cfm free air delivery which is the figure you need and it struggles to run a die grinder continuously. You are better advised to get an electric version of the tool you need and save money on the price of the compressor and the amount of electricity used plus the electric version will not ice up, freeze your hands and send you deaf.

Electric items probably cheapest.

I have been using two ALIDI compressors in tandem, happy with it and can run the air drill well (and this is better than my elec one for drilling rivet holes...)..

Not done spaying yet, some guns use a lot of air choose carefully.. The ALDI stuff seems to be matched to there compressors, so when you have two it all seems to work quite well..

Use the compressor when you need compressed air.. Great for dusting off, blowing up tires ect..

How have you linked the two together?

I've got an old 1.5hp aldi and a more modern 2.0hp aldi. The 2.0 has a full pressure out connector i was planning on connecting to the output of the 1.5 .... just worried i'll be putting pressure where its not supposed to go and blow something.

got an upright one with 100 ltr reciever paid a bit more to have upright but when space is a premium its worth it

Got about a 2 ft square footprint

Connected High pressure side's together.. (both had a high pressure outlet, before the regulator). Only snag is you must not disconnect the Quick release hose connecting them as one side will shut off the other will not so as 24ltrs at 115psi venting out of the hose not good!
