Help: Iwata Eclipse HP-cs Air leak….

[artman51164]

My Iwata right out of the box air leaks without depressing the trigger from where the needle exits through nozzle.

Now I had a similar issue a week ago w/ H&S infinity that it took me a while to figure out but I finally fixed it by stretching the air valve spring so that it has more tension in keeping the air blunger closed.

I retuned my Iwata and got a replacement. Haven’t tried the new one yet.

Have anyone experienced this type of issue with your Iwata ?

I have not had that issue with a new airbrush. But a air leak like that is usually due to the air valve o-ring being bad.

Unless the trigger had trouble coming back up after pressing down. Then the plunger could some how be dirty or like you had earlier the spring could be weak.

On the H&S, their spring retaining screw has quite a lot of adjustment compared to other brands. Chances are the screw was just backed out a little - they tend to do that from time to time. A turn in will usually resolve any failure for the valve to close.

I had mine turned all the way and same issue so that’s when decided to increase the spring tension on my H&S. Works now. But for the Iwata new from box to have that issue is odd.

I have a super soft spring in my H&S without much tension on the spring, and it seals fine... the teflon at the top of the air valve is probably a bit tight on the air valve stem. It will probably wear in a bit with time...

The Iwata probably just had a bit of dirt or debris that got stuck between the sealing surface and the o-ring. It is a normal schrader type valve and seal, so not terribly complicated.
