My old foamers were PVC and resided in the ER. Foam was delivered to the bays by 3/4" tubing...Not perfect, but worked...The 1.5" x 10" long PVC foamers had nylon scrubby in each end, hollow in the middle. Made great foam, just took too long to get to the bays. That's why I switched to the 3/4" brass and put them above the bays. The time it takes to get foam to the brush is a lot shorter now. As you can see in the thread I posted, the 3/4" brass pipe still makes good foam.2Biz - My foam generators are PVC ( not sure if they are homemade or commercial) and had about 3" of yellow scrubbie/netting in it. Seemed pretty minimal.
I'd still try a bigger differentiation between product and air.Earl Weis - I have the numbers switched - 40 psi on the product and 30psi on the air. Sorry about that.
I wish I had the knowledge you have, but I have only been at this a year. I'm just happy I'm able to keep the place running mechanically.
Yes - my foamers are directly above the bay. I'll take a pic of the setup but it's basically a brass fitting with 3 lines coming in ( product, air, weep water ) and the foamer on the output side heading down to the bay.My old foamers were PVC and resided in the ER.

BTW, it doesn't matter whether you use a Procon or flojet, they both produce volume and pressure. The key is to deliver the same volume of soap and air regardless of how many bays are using the FB. Something to consider.
Gonna play with it for a bit before my salesman comes. I might try pulling the foamers and trying with no material inside, and then with the SS dish scrubbies I've seen mentioned.I'd still try a bigger differentiation between product and air.
The very first thing I’d have done is increase the tip size up at least one tip size or maybe 2 on the surfactant side on the Blendco setup, I would have done this on the 28th. My Foamers are nothing more than a 1" piece of pipe with both air and chemical coming in the bottom and one line coming out the top that goes to the bay. My Foamers haven't been touched in over 25 years, everything works fine.Gonna play with it for a bit before my salesman comes.

Same as they were - 30psi on the air/40psi on the product.Now, what are your settings on air and liquid?
I don't think he did, but I wasn't near him 100% of the time while we were changing it out.Did he replace the "pail stinger" the PVC pipe that goes into the foam brush soap container?
