you should feel a constant breeze
the idea behind the mask it that there in enough air been forced through the seal around your face so that nothing can be inhaled back in
so there wont be a blowing gale

Be sure you've not got it on a regulator airline, you really need it to have full pressure from the compressor, the built in reg will sort the pressure at the mask.
As snooper said, you need enough air to cause a positive pressure in the mask, so that when you inhale, you're getting air from the line and not from around the mask.

Hope I'm not being too obvious. Make sure the compressor is in a different 'room' to the one you are spraying in.

Thanks for all the replys, really appreciated. 
The spec for the compressor can be seen below.
COMPRESSOR
1.5hp
8 bar (116psi)
198l/min (7cfm)
50L
DEVILBISS AIR FED MASK
3.8 Bar (55PSI)
140l/min (4.9SCFM)
I was spraying outdoors, so what I did was locate the compressor in a shed, with the doors slightly open, to allow air movement. However I did connect a 10M air line from the compressor to the mask.

I'm only using this compressor for the mask. I use another separate compressor for the spray gun.
The compressor I have is like this, with two dials and a regulator to control the air. So from what I can tell mines is connected to a regulator airline.
There isn't any regulator for the mask?...or should there be?...how can I tell?
When I was using this set up, I couldn't smell any of the paint that I was lying down, which was a good sign. On the other hand I've read isosynates is odorless.
I could only feel a slight bit of air coming into the mask, just enough to stop the condensation build up on the visor.

the compressor you have isnt really big enough to run a spray gun and an air fed mask even a 3hp 14cfm struggles to do it properly.
and you wont smell the paint but if the compressor is sucking in the paint then it will be blocking your mask filter up in no time

You need proper filtration on the air feed from the receiver to the mask or you will be breathing all kinds of stuff, oil, water, perhaps legionella even.

I would prefer a decent filter personally your carbon one in the mask will block up sooner without none at all like you are now.
While on a recent training course with a major European compressor manufacturer one of the trainers stated that they would not guarantee that the air from their range of oil free screw compressors, would be free from oil contamination. The reason for this was that there is so much oil mist in the atmosphere. The only way they would say the air from their compressors was to use the correct filters that are properly installed and maintained.
When we test compressed air for breathing masks the 4 basic tests are for oil contamination, excessive water, carbon dioxide and carbon monoxide.

when i used one of these air-fed masks i was amazed at the amount of air these things require. i had a very large compressor on it and it didn't cope with the dellivery. ended up buying a 3m mask which worked really well.
whatever you use, if you can taste paint, even just a little, its not working.

if the paint fumes of 2k were affecting u it just makes u feel a bit sickly and some fresh air generaly soon makes u feel betterThe compressor I have is like this, with two dials and a regulator to control the air. So from what I can tell mines is connected to a regulator airline.

Is that so????
I'm not sure brightspark that this is very good advice, but I'm not going down that road again.
That damn stuff can cause serious LONG TERM health problems.
My simple advice, protect yourself to the hilt, don't leave anything to chance, you should have positive pressure in your air fed mask, you should be able to hear the air coming in, and you should feel the cool of the air stream. And that air should be filtered from the compressor
Anything else can cause you problems, of which there is no cure, so I don't think it's a laughing matter really.
