Compressor Issues

[G7rev]

Hi am after some help with an issue Im having with my compressor- I have an air saw, small air cutter and now a air sander. They just don't seem to have enough poke in them to do anything- the cutter goes but just stops on the thinnest of metal, the air sander doesn't seem to grind any of my welds down- the air chisel on the other hand works fine?

 

what could I look at- I keep upping the pressure to see if that makes a difference- am a bit frustrated really

cheers

How much pressure do you have ?

[Grizzley Dell]

what size comp do you have? psi isnt everything. im no expert but its got a lot to do with how much pressure it can sustain or so im told. i had similar probs with my small comp so i bought a monster 200 litre tank and a massive twin pump, no probs now.

On mine i took the cover off where the push button is and wound down the bolt which shuts the power off when it gets to pressure, i managed to get another 2 bar out of it, anymore and the safety valve would blow off!

 

Oh arr

its not so much the psi/bar but the CFM (Cubic Feet per Minute) of you compressor. i first had a 1.5hp 50ltr comp years ago and i could sustain a fart for longer. to run air tools such as cut-off saws or die grinders or impact wrench the higher the cfm the better, ideally a good 14cfm will run just about anything.

i'll have a look at the size and make and post up

You need the biggest you can afford realy, Clarke do some cheap ones that are fine for home use, but they can get noisey!
