difference's between Devilbiss Finishline Vizi-60 and devilbiss MPV-623 airfed masks?

Raining on you`r parade again but you need a 1/2" port reg, and bigger bore airline.

I'd rather know than not know-it's a good thing you said about the coalescing filter otherwise I would'nt have one.

I looked in the mpv-623 and mpv-628 manual and it says that the correct devilbiss air supply line that connects to the reg is fitted with 1/4" fittings and is 5/16 bore ,also the small supplied airline from the reg to the mask is 5/16 bore which is about 8mm. It says if the supply hose length is longer than 10m then a portable coalescing filter is needed at 10m from the mask.

where did you read that you need a larger bore and 1/2 fittings? Or is it because of the 50m length?

I think eil could be right here, you'll get quite a pressure drop over 50m, especially running a mask and gun from the same line, but then if it works, no prob!!!

deffo need 1/2inch pipe there best use eurofittings as well there a larger bore

I'm just running the mask from the compressor nothing else.Surely ss long as it's at the correct operating pressure at the mask it should work.

It does'nt saying anything about using 1/2" pipe in the manual even for longer lengths.

if it's just the mask you're running then you should be fine, add a gun to it and you'll be losing pressure.

It was in the vizi instructions which I cant get me hands on now it asked for a minimum 10mm or 3/8" airline but that was for both gun and mask as already said. Ive got my supply to the filters coming in on a 3/4" copper pipe with 1/2" BSP fittings then 10mm bore 10M length airline, had to have the regulator cranked up to near 100psi to keep 30 psi at the gun, but as you said you will be using a separate feed for each, a case of suck it and see let us know how you get along.

will do,should be priming in a week hopefully. I'll put a reg just before the mask to see what the pressure is.

You will be surprised how much water and oil is separated out, I was, as there wasn't hardly any at all in the 25micron filter, and I have a 40micron on all the outlets of the three reservoirs that I coupled together.
