air tools & filters
AdamR - 5/12/07 at 12:16 PM

I've just bought a compressor and lots of tools and need to check a couple of things before I get stuck in to a load of spraying over Christmas.

The compressor is not one of the cheap oil free ones so there will be oil in the airflow. This is good news for the tools as they need the lubrication, but bad news for spraying as I'll get oil splatter mixing with the paint. Am I right so far?

Can someone tell me exactly what type of filters/separators I need to use in each case?

The bloke that sold me the compressor has just been using a water separator for both air tool use and spraying and says he's had no problems... but that doesn't sound right to me.

I wouldn't spray over christmas, it'll be too cold and too much moisture in the air.

a water filter was enough on mine

Dan, that's what I thought, but the filters available at machine mart are not specified as either water or oil?

For example:

Is this one water or oil?

What about this one?

And do I need an inline lubricator jobby like this one for air tools?

I'll be spraying POR15, which apparently likes moisture.

As for me a good dosing of brandy and Christmas pudding should keep me warm...

when i biught mine last year, the guy told me not to bother with an in line oiler. for the amount we'd use it for DIY (as in not inductrial) a squirt of WD40 into the inlet would be enough every day before use

Am I right in thinking it should be a modest amount of WD40 and that if you put too much in it can hydraulic lock the tool???

Hi mate just use a inline water filter before your pressure regulator the one you adjust for your airline .if you want to oil your airtools just put a few drops down the air connector and fit your airline and just run the tool for a min this should be fine ,for longer useage you can buy a tooloiler fitted to the tool you use they sell them at halfords o you can attach one to the tool side of your regulator hope this helps .

if you put too much in, it just blows out of the exhaust port of the tool.

I have a cheap combined separator and regulator from machine mart and I don't get bother spraying.
