Water spurting out of Air brush hose

Hello everyone

I'm new to the forum, in fact i joined to post this, because I'm at my wits end.

My name is James, I'm 31, I've been painting minis for about 3 years and about a month ago i decided to start airbushing.

I don't know where else to turn other buying an entire new rig, but my fear is this problem will follow me to the next compressor.

Water is spurting out of my hose. I start spraying and its fine, but after a few minutes a blast of water will jet out and ruin the work i did. When i unscrew the hose from the brush there are little spurts of water coming out.

I have a moisture trap that the hose runs through. I think everything is working as it should. But i simply don't know enough to troubleshoot. Google yields vauge results. Was hoping someone out there could reach out and help me.

I'll upload a pic of what I'm working with to help

Have few questions. How long is that hose? Does that air tank has drain valve? If it does, do you drain it? I don't have a clue about those mini compressors, so I was just wondering....

People also use moisture trap on the airbrush it self. Looks like this, you have few options on google

lol

First, let me thank you for replying i was worried others might not care to chime in.

It's a 6 foot hose. The only thing i can do on this rig is depress the pin under the moisture trap and it will expell air. Some slight condensation will be built up, but once the trap is empty, the water contiues to spurt out of the hose

no such thing like this right?

Don't worry, Dragon hunter will chime in :D
 
No, no sir. Its a very small tankless compressor.
I don't have a clue. I have 10 meter hose where I can get moisture inside I tried it with air pistol, but then I have moisture trap like you have and from there 2 meter hose, something like you are using and I don't have issues with moisture.

Guys here will know, it just take some time to gather them on forum. At least you gave little more info while waiting for solution.

I think that small pistol grip moisture trap could help you, but it's weird you get it now. Are you from amazon jungle or something? Lots of moisture in the air? lol

No sir, new bedford Massachusetts, and i agree completely... why now all of a sudden did this happen ?!

Been using it for around 2 months give or take... no issues other than now.

Bear in mind I am noob and I talk nonsense all the time. But I wonder if it's possible to get a lot of water in that tank, cause you can't drain it and then instead of air compressor pushes lots of moisture in your hose. I mean is it possible that in your 2 months of use you got so much water in that tank? -.- I wonder... This thread will be interesting read when guys chime in. :)

I think anything is possible. Where would the water be collecting tho ?

I unscrewed the hose from the regulator itself completely, and no water spurts from the regulator hole where the hose attaches.

It seems as if water is magically coming out from the hose, as stupid as that sounds

hahahaahaha :D
 
Like I told you, I don't have a clue about small compressors and what I learned about mine I learned from great community here.:cool:
 
My wild guess would be that if small air tanks don't have drain valve they don't need it? -.-

edit: But then why would you need moisture trap. lol I take my sentence back! :D

a)condensation in your hose if hose is to long.

b)it seems some guys experience this phenomenon too. They say an overheating compressor head will cause water to form in the hose.

c)guy had the same problem, but the splatter appears only after about half an hour of painting. He guesses it's because the compressor heats up and so is the air and it condenses not only in the moisture trap but in the hose too.

d)Well, the next morning, I put the compressor down on the floor and started painting. Initially, I had water. But it went away and I sprayed fine. Its one of three things. Either having the compressor on the table allows water to flow to the AB instead of the moisture trap OR practicing overheated the compressor OR my garage is too cold at night for ABing.
Problem solved, for now

I was checking a little for you. We need double cool emoticon or even better Deadpool emoticon. :cool::cool:

Using a small tankless compressor creates a lot of heat .When the ambient temperature of your work space is cooler than the air going through your hose it is possible to have condensation build up after your moisture trap in side your hose. A pistol grip moisture trap should help Also perhaps allow some time between painting to allow the compressor to cool.
 
One thing that different is the other day, i was spraying for longer than usual and the compressor just shut off. I touched it and it was too hot to hold my hand there.

Could this have caused some underlying perma damage ?

some compressors have shut-off switch so you don't damage them when:

quote: are equipped with a switch which includes an oil temperature sensor. If the compressor oil gets too hot, the switch sends a signal to the on-off controller to disengage the air compressor’s clutch. This shuts down the system and prevents high temperature related damage.


Why is my compressor shutting off?

If your compressor trips on over temperature, it could be for any of the following reasons:

  • Ambient temperature too high or not enough ventilation
  • Too low oil level
  • Wrong type of oil being used
  • Dirty oil cooler
  • Thermostatic valve not working
  • Dirt / obstruction in oil lines
  • Plugged oil filter
  • Restricted air flow over the air to liquid cooler
  • Too high an engine liquid coolant supply temperature in a liquid to liquid cooler
  • Faulty temperature switch

Do those small compressors have shut off switches? Yours is oil free I would guess.
