Laser M5 LP Air problem

[bigleo48]

All,

My soaps and other foaming low pressure products seem to need more and more air to mix properly (and prevent striping). When I first opened up a couple of years ago, 60lbs was all I needed, but now it's closer to 100!

The air systems seems to be OK, solenoid and air line push air freely out through the arch. I have a manifold in the bay that ties in all the chems via a check valve.

Any ideas? BigLeo

Is there a chamber in that manifold that could be getting blocked with build-up?

On the 4000 there is a check valve below the low pressure unloader. Doesn't fail often, but can cause the stringing soap stream.

As stated above ,on the 4000 there is a check valve after all the low pressure check valves to keep HP from getting back in into the LP side. If that check valve fails it will cause stripping. Also on the 4000 ,there is a foamer located in the "pipe" on the manifold. I usually just remove the foamer ,from out of the pipe.

Don't think the M5 is exactly the same, here is a pictures of my setup. Both Black hoses are LP soap, red is LP wax and air. Will need to ckeck ckeck valves and solenoids

There should be a "scrubby" in the manifold pictured, it is inside the pipe where the 2 green or black clamps bolt on. If you take the manifold apart from the end where the soaps and air go in, some time the scrubby (its like a sos pad but plastic) some times gets bunched up in the down stream end.
There is a pin that stops it from going down to the big check valve and if this is the problem you just pull it out and streach it out and reinsert.
Some operators just remove and claim they get just as good soap foam with out the issues of it packing up on one end and preventing easy flow.

Hope this helps

Big. the foamer is in the pipe that the clamps are around.

I remove the foamer , and our soaps foam up fine. I would not recommend it though unless you use a very foamy type of soap. Be sure if you use the foamer to reinstall the nipple with the pin in it so that the foamer does not get pushed into the check valve.

The brass check ,is usually the problem when the soap streams ,or does not cover well, But as Mike has stated the foamer can be crusted up.

Mike & Lag,

You guys were right on the money. The scrubby was bunched up at the end. I pulled it out, cleaned it and reinserted. Turn the pressure back down to 50lbs, and voila! All is good. Thanks...that one had me puzzled as I didn't realize there even was a foamer inline.
