airfed mask/ compressor problem

[tom_crown]

hi guys iv recently bought an devilbiss air fed mask, whilst using it and spraying the pressure on my compressor drops very quickly and is not maintaining, is there anything that i can do to help maintain the pressure

furthermore are there any masks that will only let air through when i breathe in?

many thanks

Hi, if I remember from my spraying days a devil. mask uses about 5-6 cfm. Your gun probably is using 10- 12 cfm. How bigs your compressor?

Easy way is to put a small clamp on the pvc supply pipe to your helmet and reduce airflow slightly. This may sound daft but the helmets work on positive pressure ie nothing gets round the seals.

reduce the pressure until you detect paint then up slightly.

Be very carefull if you are using 2K

Frankly I wouldn't recommend that method, probably better to get (beg or borrow or buy) another compressor and join the two.

Most air fed masks rely on positive pressure inside the mask to keep fumes outside. Any lowering of the pressure and you risk fumes being sucked in as you breathe. The seal around the face alone is not enough to prevent this.

You need a larger compressor or a second one purely for breathing air.

i agree dont mess with pressure to the mask that will be the amount needed to stay safe

which devilbiss mask is it?

you need a lot of cfm to power the mask and a gun-especially if the gun is hvlp.

are you using a gun with your mask or have you got a seperate compressor?

if it's the devilbiss mpv-623 mask 140l/min is absolute minimum-

what's the free air delivery of your compressor/s?

danelectro is right, I must have had too much beer last night

it wouldn't be a good idea if your using 2 pack.

Hire/Borrow a compressor and use it just to feed your mask.
