Foamer

I only said the Idea was sound! It's probably that new space age polymer.
 
We apply foam through our pressure washer.All you need is a foaming wand that mixes air with the foaming agent.We were looking into seperate units when we discovered we could do it with our P.W.
You need an upstream injector.If you have a machine with a bypass tank you will need to run the machine with the valve open, fill the line, and shut the valve.If you leave the valve open the pump will suck the chem when you are in nuteral, and over flow it from the bypass tank, and all your soap will be gone in 2 minutes.
 
We have a few of those and they work pretty good. I have never had any luck with the upstream type that Mr. Z. is talking about. These ones have a couple of drawbacks, the pump lasts about a minute maybe 2 depending on how much chem you have in the tank and the wand and hose that come with them are too short so ask for extra hose and a longer wand. I would say next to the duct spinner and the magnetic scraper it is one of the best tools ever invented for exhaust cleaners ;)

Matt, Are you saying you have the one I was asking about, it doesn't look like the same thing. If so what chemical are you using, that looks like great foam consistency, how long does it stay in place.
 
Thats the same one, I just got a longer wand (I think 3') and more hose, 15 or so feet. The manufacturer said that longer than that on those and the air has a hard time making it to the wand which is where the foam is made. You can vary the consistency at the tank with a little knob that allows more of less air to pass to the wand.

The chemical is just caustic and a foaming agent you can get at any chemical supplier, make sure you tell him it is for caustics, the first one he gave actually reduced the effectiveness of our caustic and after we told him what it was for he gave us this one that works with it. The foam lasts about 1/2 hr before it really starts to break down and the more grease there is the faster the foam dissolves. You really need to let it sit on there and work though as it is no where near as potent as straight chem. If you want to get a unit that makes more foam you are looking at anywhere between $600-$1000. These units will spit it out about twice as fast as the pump up models but they are a lot more cumbersome.

John-
Do you use the wand foamer that connects to the end of your wand? Or do you pump chemical through your machine?
 
Sure a lot braver than me. I don't know if the weaker foam carries as much potential for damage as strong, hot chem solution, but usually we cover links with tin foil before spraying chem. We can make several passes and allow to dwell as long as needed without concern. Eliminates scraping. Anyone else using this simple method?

Matt,

What kind of foaming agent are you using? Will corn starch work as a foamer in that pump up?
 
I dont know about the corn starch but I doubt it. I have idea what kind of foaming agent it it. I just explained the situation to my chemical supplier and he kept giving us samples until we found the right one. I will tell you that dishwashing soap will not work, we thought for the longest time that the foamers were a piece of crap because we couldn't get them to foam right using dishwashing liquid. I think it has something to do with the caustic and the PH balance.
 
Matt have you ever used caustic thickened for longer dwell time?
 
Still cant beat the chemicals applied under hot water and pressure.
 
Everything we do is Downstream injection and metered before entering the high pressure pump.
I dont care for the X jet, Just another Gizmo in my opinion - It has its place in exterior washing . If I need to apply chems for a dwell time its applied via pump up sprayer.
