Neo airbrush

Thank you in advance I am a newbie And struggling to get working right. is the needle cap the same for all nozzle sizes ? I am struggling to get a good paint flow. No matter what the air pressure, I’ve tried between 15 and 50 psi. just out of curiosity I loosened the nozzle cap about a turn and a drastic change in paint flow occurred. I’m confused. Using a 3.5 nozzle which I’ve replaced twice. Anyone else have thi issue ?
Thank you. Marty
 
Yes, the nozzle and nozzle cap work together as a pair. On just about every modern airbrush today, the nozzle cap is designed to be screwed all the way on when in use.

The Neo is an interesting brush. It has one of the smallest gaps between nozzle cap cap and nozzle on the market. This allows the brush to operate fairly well at lower air pressures. But, this also prevents it from being able to respond to higher pressures - they just never make it out the front without being reduced to a fraction of what you have set. This makes getting your paint reduction correct a key element of finding success with the NEO. Instead of upping air pressure, I would set up at maybe 25 psi, add a drop of paint to the brush, and then a drop of reducer or water - test spray to check performance. If it is not flowing, add another drop of reducer or water - repeat. Now, every color can be a bit different, and some will flow well right away. Some seem stickier than others, and may require a little more reduction.

Be patient, and try to learn what the bursh is really doing when it does or doesn;t do what you want it to.
 
I dont know anything about the Neo, but it might help if You let us know what paint You are using and if You have tried it thinned down. I am sure there is someone here who will be able to help :)
 
As long as it’s a properly cleaned and maintained airbrush, I think you should be good and it’s probably just an issue with thinning your paint properly. I’ve said it often before; do you want to get your paint or medium down to about the consistency of milk in order to have it flow smoothly through your airbrush. Thinner than that, it will spider and run often. Too thick, it will be inconsistent, spatter, or not spray at all.

For typical art and Illustration mediums (airbrush paints, inks, dyes, watercolors, gouache, acrylics, etc.) an air pressure of approximately 30 psi (2 bar) will work just fine.
 
Neo can also be temprimental with the nozzle seating, make sure the oring is not pinched and making it sit at an angle. The oring should sit inside the body fully and the nozzle meet flush.

If you cannot get it to seat straight with the oring you can revert back to beeswax as long as it will not react with your paint or cleaner. Also the head may benefit from the same wax on the thread.
