Water separator not doing it job

I have this iwata is-925 air brush gun ,the water separator does not seem to be doing its job ,i am getting water come through the gun,when using the gun and looking at the water trap site glass the water seems to be splashed up against the glass,when i push the water release not much water comes out ie more water comes out of the gun than that what should be caught in the trap,looking at the lay out on the regulator there are 4 holes one is the air inlet which is what it is but for the hole marked out it is bunged off with a cap on the left and right which has no marking the pressure gauge is attached which operates fine on the oppisite side is the hose that goes to the gun is this the problem that i am having is this hose ment to be connected to the hole marked out one woul think so ,or does it not matter can either 3 holes be used and the water separator work on all of them ,hope you can under stand my english be good to here from you

The iwata 925, although a good compressor, does not have a tank to store air and allow the air to cool somewhat before going into the water trap. For best results, the water trap needs to be far enough away from the compressor to allow the compressed air to cool allowing water to condense out. Go to a compressor repair shop in your area and have them make an air tank out of used parts and have them move the water seperator from the compressor to the remote tank. It should not cost more than thirty dollars or so. If space is a problem then just purchase an extra hose and attach an inline seperator like the one shown here: http://www.dickblick.com/zz269/23/ , Coil the hose and hang on wall. The coils will help to catch water. Be sure to empty the extra hose frequently. Good Luck

If your water separator is not doing the job then you have too much moisture in the compressor tank. Turn on the air relief valve to release the air. Be sure it is at a low point so that the moisture in the tank will also escape. Once the tank is completely empty screw the relief valve shut, start the compressor and then check the output for moisture. You should be good to go.

My newish SIP TN3/100D v twin compressor will not pump above 100psi !!??


100 psi is capable of running the gun
what the problem is the volume of air supplied to the gun
check the specification requiring the air usage for the gun against the volume supplied by the compressor
if you gun requires 20 c/ft of air /min and the compressor is only capable of 15c/ft of air /min, then the volume is too low so the pressure will not build up
modern impact 1/2 guns will operate quite well on 80 psi unless the gun is leaking internally
another point is this-- impact guns come in two configurations-- single hammer and double hammer
double hammer give 2 hits for each revolution of the air motor and there fore use less air to do the job
add the fact with 2 hammers , the torque applied is generally higher than single hammer units
the reality is this , the compressor capacity in c/ft/min should be 2 times that required or used by the tool

I am using an iwata eclipse cs airbrush with an iwata compressor. the comopressor seems to be working fine when power, but the airbrush is not getting and air. when i push down for air release, nothing...


Air brushes us a Theory called a "venturi" in where air pressure lowers the pressure where the paint is kept and causes it to go out the nozzle. I would try seeing if there is an obstruction in the hoses to the brush and confirm that the compressor is moving air. If none of these things are an issue also while cleaning the parts may give the appearance that the item is clean then try soaking them over night in paint thinner and replacing the O-rings and gaskets.

Moisture is coming through my air compressor hose and into my airbrush gun, resulting in splats. if i press the gun for air moisture (water) still comes thru. when the gun was removes the moisture was felt...


When you compress air the moisture in the air condenses and pools in the tank, all compressors do this whether new or old. If there is water built up in your the tank it will come out when you release the air. There is a valve on the bottom of the tank you have to open from time to time to drain this water from the tank. Take the compressor outside if possible or have something under the valve to catch the water as it comes out. Open the valve slowly or it will blow the dirty/rusty water all over. Campbell Hausfeld and some other companies make filter/driers to put on your supply line if the air needs to be dry for your use. Most box stores (Home Dept, Lowe's, etc.) carry these driers or can order them for you.

Water coming out airbush from hose


An in-line water separator should be used before the supply line, a good air filter wouldn't hurt either.

Bubbles in color cup of airbrush


I assume you have adjusted the nozzle... On my unit, there is a SMALL hole in the cap for the cups to let in air above the paint. Also OFTEN the paint must be thinned to use in an airbrush. Since you havent been able to draw water even, thinning is NOT the problem.

The airbrush aspirates the paint by Bernouli's principle, that is where there is higher velocity of a fluid, there is a lower pressure. The nozzle creates that and the adjustment is important. On mine which is a "Wren", I think by Binks there is a conical piece that the paint comes out of with a throttling needle. This has the be unscrewed to open the paint path and adjust it. The air flows at high speed around this cone creating a vacuum.

The headline says "Eclipse" but that is a gravity feed so I suspect that is the old Fixya problem of having incomplete choices to pick from.

I have some severe free flow goin on, on my hpbcs iwata eclipse


It sounds like you have a problem with the air valve. Possible deterioration of the valve material? I am not sure what they use, but if it is a rubber the cleaning thinner MAY have destroyed its properties if the cleaner got into the air path and valve.

My iwata hpc is pushing air back through the paint cup


Try replacing cup gasket first then clean all inlets and outlets completely, check that all valves operate properally, and all seals and o-rings are in good condition. Clean and lubricate adjustment fluid valve.

Regulator will not turn


I AGREE WITH EDITOR 925. ALSO MAKE SURE YOUR NOT TRYING TO EXCEED THE PSI OF THE REGULATOR OR COMPRESSOR. TYPICALLY YOU PULL THE CAP UP A TINY BIT AND TURN IT. IT MAY BE MAXED OUT ALSO.
