Air is coming out of the nozzle but the paint is not coming out.

nozzle head might be shut try turning it to open, you should here air coming out if air comes out but no paint comes out then paint is to thick and might need thinning, hope it helps.

this is usually caused by:

1. water in pressure tank of the compressor - clean the compressor holding tank
2. faulty valve in direct drive compressor (rare!)
3. dirty needle/gasket in the piece.
4. insufficient air flow

regarding 1:
stop the compressor,
open drain on separator and let all liquid out
allow pressure to drop to atmospheric
open drain valve on the tank and drain the content
on the compressor body find oil drain and drain oil
fill with new oil according to instruction on your compressor
close drain valve on the tank and separator
start compressor and check if problem is solved

re 2:
return valve is too difficult to change without specific model knowledge

re 3:
fill 1/3 (pint/500ml or less container)gun container with paint stripper and spray it directly to the sink or other container on full blast - WEAR SAFETY MASK, GOGGLES AND GLOVES! STRIPPER WILL BURN YOUR SKIN!
fill same level with water or solvent and run again, this operation should remove most of residual paints in nozzles and pipes.
check now nozzle for cleanliness and needle assembly, clean what necessary, use bit of vaseline when you will put it back together.
check for consistency of spray on piece of butcher paper with your usual paint. if problem solved - you are fine!

re4;
increase air flow... this actually should be done first.

for better instruction - please provide with model of the gun and paint used.

your comment and rating will be appreciated.

most common problem is paint, it is too thick, second problem is your feedline/needle block.

before you put your airbrush apart - remove paint from container, wash well with appropriate solvent, put some of this solvent to the container and try spraying, if no solvent comes out - adjust needle stopper, this is dual action! have needle adjustment! as you did not give the model and manufacturer, this can be only and only general advice!

if still nothing comes out - prepare butcher paper, disconnect airline from the airbrush, disassemble the gun putting the parts on the paper in order in which you disassemble it. wipe off the needle with soft cloth, use drop of solvent if needed. clean body and container assembly and check for liquid flow from container to the nozzle, it should be steady drop, if there is no flow, then use special brush and if you do not have one, soft copper wire of smaller diameter than the passage to clean mechanically the passage. check again for liquid flow. re-assemble the gun, use bit of vaseline or paraffin to grease the needle and moving parts before re-assembly.

use solvent first to check liquid flow. adjust needle, pattern and size of the max flow. remove solvent, put paint into the container and use normally.

in 0.2 nozzle, paint should be of virtually water density... if this is opaque paint - need to be strained as any impurities and bigger chunks will clog the outflow...

hope this advice will help you with your problem - and i do earn some points from you...

These guns are made to use about 35 - 45 lbs psi and the paint needs to be thinned a bit. You will have to experiment with the thinning for how much coverage, how much humidity, what type of paint and thinner it takes.

when you pull the trigger can u see the needle moving backward? if so, then it's either the paint is too thick compare to the nozzle size or the passage for paint is blocked. try to take the nozzle, needle and the cup off and give it a good clean!

Reduce the air pressure,and put a water separator in line.

no fluid gets to nozzle or comes from nozzle.
sounds like your fluid line is pluged or the gun is pluged at or before the tip

My #91011 One Quart is not a gravity feed, it is air compressor fee fed. My problem is the nozzle will not fan out . It only blows a round spray mist. ?

i dont have so much as a solution as a couple of things you can try to figure out whats going wrong.

make sure your compressor can handle 10.5 CFM @ 50psi
hook up the gun and dry spray it to check for blockages in the air supply
if the air comes through strong and constant, fill the paint hopper with water and spray until empty
if the water comes through constant, add half of the hopper with paint thinned with penetrol or floetrol
if the paint is coming out weak or spotty, make sure the vent cap is open on the paint hopper
if the cap on the hopper doesnt have a vent, try spraying with the cap off or cracked a bit.
if that doesnt work take off the hopper and check the filter for blockages.

i suggest straining all your paint before pouring it into the hopper

top one should be paint flow and the bottom one should be air flow. that is how my gun works anyway. Hope this helps you out. mine is a siphon type gun may be different for a gravity gun. Mike
