Tri Foam in Self Serve

[pcb]

I'm trying to get the tri foam in my self serve bays to spray properly and feel like I've tried everything I can think of. Hoping someone might have an idea I haven't tried. I use the same product and dilution in my tunnel, laser wash, and water wizards and it has no problem foaming consistently, but in the self serve it doesn't want to foam and when I get enough air to foam some it sprays a few seconds then spits just air for a few seconds.

I'm using a procon pump on coleman setup. Have foamers in line. Added the $150 Ginsan foam gun on a bay to see if the foamer at the nozzle would help. Still does same thing. I've tried lower pressure and higher pressure. I've made it strong enough to stain the walls and same thing. I've tried bigger tips and smaller tips on foam gun. Hoping someone might have an idea.

I had a similar issue, but my problem was that my procon pump was bad. It pumped for a second and then didn't go anymore.

What size tip are you using in your guns? Are the foam generators clean and allowing full flow? Maybe try removing a generator to see if that fixes your issue.

I've replaced the pump twice. I believe the ginsan gun came with a 6570 and I can't remember the other size. I'll have to check. It was one Mep had said he used a long time ago. Foamers are clean so I'll try taking one out. Thanks

70 is very big, we are using either a 40 or 25 size nozzle on the 3x guns

I just went through this recently on an AirLogic system. Same diagnostic steps you took. Kind of a PIA.
Went from a pink tip all the way to a blue tip, added and removed a foam generator, put the FloJet/air mixture from as low as 25/20 to 85/65 psi.
I've got it working pretty good (video) and this is where I've ended up for now:
* No foam generator
* Orange tip for hydrominder
* Chemical 80 air 55 (seems high to me but it works)
* Returned an entire pallet of a 'well known house brand' of triple foam soap in favor of JBS (this is a big one, the soap was coagulating and clumping in the sealed containers even before opening and contaminated a brand-new system causing f#@%ing algae blooms (snot) in the mixing tanks which clogged the hydrominder tips and fouled everything downstream.
*Also make sure there are NO restrictions in your system from the FloJet to the gun connection (reducer fittings, wrong hose size, etc.)

Thanks for the help. I'll look over the system and see if I can find something.

make sure your running the chemical through 3/8” line as 1/4” doesn’t give the volume needed. 1/4” is fine for the air though
