need help comparing 2 air compressors???

[Doc Sprocket]

In order to determine air tool suitability, you need to know the PROPER compressor ratings. Should be something like "4.5CFM@90 PSI". You would then compare the airflow requirements of the tool you are examining. IF the above compressor rating were true, you'd have no problem with, say, an air drill that requires 3.8CFM. On the other hand, and orbital sander that requires 5.5 CFM, will not at all be happy with it's new home.

Sometimes, you can safely get a tool that requires more than your compressor can deliver, BUT- you'll find yourself standing around waiting for your tank to recover in between bursts.

Well at 5.5 cfm at 100psi u wont have much difficulty running any of those air tools

Except maybe the spray gun
Toystory will have an answer to that

U may want a right angle die grinder as well as the straight one

i thought a spray gun would work good
and what about the air impact wrench will these tools work ok with my compressor?

 

[Doc Sprocket]

With a spray gun, check the specs. You don't want a gun that requires much more than the compressor can deliver. Otherwise, as the pressure drops and the pump struggles to catch up, you'll lose pressure at the gun and the spray pattern and atomization will take a sump on you. Not at all helpful when you're trying to get a nice paint job on something.

this is the spray gun that comes with the kit http://www.aldi.ie/ie/html/offers/special_buys3_26196.htm

 

[Doc Sprocket]

Looking at the overall size of it, it will probably be okay, but the only way to be sure is the specs- which I do not see. You may be best to contact the seller and ask.

i wont be doing any big spray jobs like a car
maybe a bumper and that would be the biggest

Before I bought my big compressor, I had a 2.5hp, 40litre direct drive compressor that put out around 7cfm. I can tell you
- that spray gun will do well
- the nail gun should be ok since it only uses quick bursts
- the cut off tool may struggle
- I don't hold out much hope for the impact gun; my 3/8 drive impact gun struggled.

A gravity fed spray gun uses much less pressure than a suction fed gun; if you stick with gravity guns you'll be fine

What kind of spray gun is that 1above den?
Is it a gravity 1 or suction

 

[Doc Sprocket]

The one you linked to? Gravity. The paint reservoir is on TOP of the gun, gravity brings the paint down. A suction gun has the reservoir below the gun body.

so of the above tools i linked
which will be ok to use with my air compressor
dont want to be buying something that wont last pissing time ?
thanks for all the help so fare

 

[fowler]

The suction ones are usually larger in capacity
But as fabroman said a suction will use more pressure and will run out faster

U can cover a decent area with the gravity fed ones if u are only painting karts and mini bikes

I would have said those tools should do alright

My 3/4 snap on gun runs off a 2 1/2 hp petrol compressor
As does my die grinder

Lol, I got the same compressor from the same shop, Lidl!

So far, I am really happy with it. The compressor performs good, the tank is loaded up pretty fast and I almost never wait for the compressor to fill the tank. Once the compressor starts and you use the impact gun, the pressure will stay the same. So you're fine on that.

Also, I got all the tools from the compressor's brand itself. To be honest, I wouldn't go for ALDI. They'll brake rather quickly...
I know that Parkside isn't a high quality brand either, but in my opinion it's much better than Aldi's.

can u tell me what tools dont work good with it just so il no
whats it like for spraying?

I'm sorry, but I don't have a spray gun. I would have bought one, but my mother didn't allow me because it would have made a lot of mess... (half of the paint will be somewhere else )

Impact gun works great. Also, the normal tool for spraying air around works great for cleaning carburetors.

so what tools did u use with it then?
when i bought the compressor lidl didnt have any tools for it
just compressor on its own

Pretty weird. At the time of the promotion they had quite a lot of tools aswell...

Got everything except spray gun and nail machine.

 

[zip kart]

have you a sander for yours?

 

[Nodroz]

Nope
