I was a Safety Officer - and yes I did mask fit tests. I will only add to Matt's excellent post above, that if using an air fed mask - the air must be 'pure' - ie moisture removed and very well filtered, and then a charcoal canister before feeding the mask. You can't just link up to any old compressor - you will be breathing carcinogenic oil fumes....... Please all - don't be tempted to use 2k paint...it's just not worth the risks.

Blimey

I've got a couple of compressors and I hook the airfed mask up to an oil-less 2hp/50L one. Personally I'm not overly concerned about higher moisture levels - afterall we all breathe fine when its foggy!

I have one of these (from this supplier) http://www.ebay.co.uk/itm/New-Devilbiss ... 2245wt_902 but I think I paid around £100 for it.

You don't want to remove all moisture from the air, but there are standards for breathing air quality.

Unless you know exactly what you are doing! ;)

I bought an oil less compressor(sealey upright type)to use with a mask but the noise it made was unbelievable!!!!!!!Bad enough the neighbours whingeing to the council about the dust,fumes etc LOL without adding noise too!Soon got rid.

wonder if you could adapt one of those 12 volt tyre inflators to run a mask,if you could filter the air,no oil contamitation,and a longer tube ,it should provide enough positive pressure inside the mask.

it should provide enough positive pressure inside the mask.

Only if you don't do much breathing!
something aimed at pumping up air beds would be better, less engineered towards pressure and more to flow.

You need about 5-7cfm for a positive pressure mask.A lot of "paint spraying compressors" dont have that.

Thursday 13th March Aldi will have a 2.5hp air compressor for sale for £89.99. Air displacement 270 ltr/min, 9.5CFM, 24ltr tank. For an extra 19.99 you can have air blow gun, air wash gun, tyre inflating gun, high pressure spray gun and 10m x 6 mm air hose.
There are also other air tools available from that date.
Well worth a look!!!
As regards 2k paint I prefer to leave it to the professionals.

The tanks the problem with that.Too small to have a useable reserve of air.You could always couple up an extra tank using an old gas bottle.Mig welding forum has plenty of advice how to do it.

In and around my workshop I have about 13hp and 450L of compressors

Thats spread out over 5 compressors though

They're also doing lots of tools, including an Air Filter Regulator with hoses for £19.99.

Any good?

I was in my local Aldi recently and managed to get the 3" cut off tool, the air shear and the air filter/regulator for less than half the price as advertised in the Thursday 13th March catalogue. The compressor was not on offer then but the Air impact wrench was but I have no need for it so did not purchase it. The remote fibre optic camera was also for sale but could not justify its purchase.
Different Aldi's seem to have different offers/reductions on at different time so it pays to keep your eyes open.

If the compressor oil they have on offer is SAE40 grade then it's good value to refill your dampers £3.99 per litre.

I have looked on the Aldi web site and there is no specification given i.e. SAE for the compressor oil.
The SIP compressor oil for use in the SIP compressor I have does not have a SAE specification on it either. It just states on the bottle that it is suitable for compressors and conforms to VC-L of DIN51352 and DIN 51506 standard?????

I expect the bottle has more information than the web site.

Not necessarily - I was recently given a petrol lawnmower (neighbour moving away) and a bottle of oil for it -no SAE number on the bottle..

Some neighbours really do take liberties!The cheek of it!

Checked the Aldi compressor oil today and it states OEP30 on the bottle.

Going back to this...

I painted a LWB transit last week (took forever!) - with the old thumper compressor (100L/~3 hp) powering the gun, and my SIP 2HP 50L outside powering the airmask.

The 2HP compressor was only just keeping up with the demand of the mask at 30PSI. Sometimes it ran fine for 45minutes, sometimes it needed to have a chance to catch up after 15 minutes - so no chance you could use anything smaller!
