Upgrading Aldi Compressor?
Ok, compressor engineers...
I have the little 25L Aldi thing that is not exactly quiet... however I don't mind the noise as the radio has a button that can out do it.
However show it the cut off saw, air ratchet or what ever it runs out of puff real quick..
If I was to get a big gas bottle, say one of the big 19kg propane bottles and replaced the receiver would that help the performance?

Interested too, got the compressor, not stopped buying air tools since  but as said the capacity is "cough" limited

I would say that it would be possible to run tools for longer due to the larger volume of air in your reciever. however if the air delivered by the
compressor is 25 CFM (for arguments sake) you will only ever be able to run a tool that consumes 25 CFM with a guarantee of performance.
getting back to using a larger reciever. if your air tools are designed to run at about 90-100psi and your aldi compressor is only capable of reaching
100 psi your larger reciever will allow you to have more flow but will loose pressure at the rate that the tool draws off quicker than the compressor
would supply.
in short it would give some improvement. would definately work if your compressor could supply say 125 psi and you only wanted to use 100. if you put
a regulator on you could get some extra performance time than the current set up.
crap explanantion but think it holds a little water

Just had a look and its 2.5hp, 9.5cfm and 115psi. Problem I reckon is the small 25L receiver.
So, if I get a 100L receiver and a 100psi regulator would that make it better without running out of air.
Obviously if I use a gas bottle it can take a lot more pressure, how about increasing the pressure??
Thanks,
Steve

I use to use mine like that for spraying and other low pressure things, works fine, but if you wanted a high pressure high cfm, you would soon run it
down again, unless it was just something like a nut gun which would be off more than on. A grinder for example would empty it, but as a "free
upgrade" its well worth doing for the extra run time it would give you. I tweaked the pressure switch too IIRC, to pump up to a higher pressure
before cutting off, but do so at your own risk!

My understanding would be that a larger reciever at 115psi rather than 100 would be the best you could hope for. but i'm not going to suggest
you start making your own pressure vessels!
I would be tempted to try 90 psi (max - no minimum) regulator and charge any safely rated reciever up to 115psi. only thing is it will take a while.
and at the end of the day the maximim continuous rating you will be able to use indefinately @100psi would be a 9CFM tool which is not a lot.

If you put more storage on the little pump it will not increase the free air displacement which is what you need, the only way to do it is with a
bigger pump. You'll get a slightly longer running time till the pressure drops then the pump will take longer to fill the increased space. CFM
is not the figure you need, FAD is more important. Your pump should be able to refill your tank and run the tools you use at the same time to be
useful.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

My mate has one of these compressors and he has finally managed to get fitting to hook up the ALDI tank to a 47KG (the biggie) PROPANE BOTTLE.
He was telling me on Monday night that he can now runn his windy gun and the compressor will "just about keep up" turning it from mmmm to
Oh So Much Better.
He connected the PROPANE tank to the fitting on the end of the Alid tank and then put in a new watertrap and regulator so the compressor out puts can
be set at pressure 1 the Big storage bottle outputs can be set at a different pressure.
How he did it was put a T on top of the bottle so he could connect the fill line and the outtput line to the same point
Scot's do it better in Kilts.

Well you probably could but I'm not saying you should. There's some serious pressure in them there compressor tanks! Each to their own but
high pressure air is one thing you won't find me mucking around with! A ready made proper size compressor is perhaps a slightly safer option....

I hooked two Aldi compressors together so double the volume and double the compressor power.

how did you "hook" the two together?

wouldn't imagine it would be too difficult to fabricate a manifold for this. you could even weld the two compressors together with a few pieces
of flat bar and have the outputs for the 2 tanks running into some steel tube with the correct push in connectors with one exit connector. that way
you could disconnect it and run them seperate if you wanted to.

I guess just a flex pipe between the two would do just fine
