hi all i'm after a new compressor but i'm not sure what size to get,it will be used for sander and spraying any iders cheers

 

If used with a DA sander, a F*****G big one, they gobble up air like theres no tomorrow, spraying is not so bad as you can use HVLP stuff, and only done a bit at a time, just look at FREE air delivery rating of sander etc, often just getting a bigger tank will pay to do as you have more reserve.

i'v got the da sander box in front of me but all it sez on it is 4cfm@90ps1,1000 rpm i can't find anything about free air.

 

this one any good ??? https://www.machinemart.co.uk/shop/p...air-compressor

 

Can't remember the exact calculation but those figures sound like they would be at 25% duty cycle i.e. only running for 15 seconds then stopped for a minute, so to get a real figure it'll consume more like 16cfm if used continuously so to power it without compromise you'd be looking at a large 3 phase jobbie supplying 25cfm at least.

 

Would probably do the job it used immtermitantely (sp) but having done extensive research when buying my last compressor, if you want workshp type performance you need three phase as even the biggest twin motor 240v compressors are just about up to ''proper'' workshop useage.

 

how long would i have to use the sander b4 i have to wait 4 the compressor to build up again?? if i was using the compressor that is on the link

 

The one in the link will cope easily with the sander you have, it's bigger than you need, but bigger is better with DA's.

thats the same compressor i've got

it's great for doing everythng i need to do with it, impact drives and stuff as well as drilling and cutting, even the air saw works fine from it and it builds up quickly once its up to pressure
