I'm not implying any deficiency in your setup. Just a correction of your physics.
I know Lee. Remember Summerfest 2002 in St. Louis? You and Justin brought an anemometer which turned out to be quite revealing.People think sometimes that they are measuring airflow by actually measuring something else, like lift or Hg.
This would be like calculating a water pump's flow with a pressure gauge.
Airflow is measured with an anemometer.
They don't make the Titan 875 anymore.HM Titan still comes with a 5.9, no? Are they the only mega mount with the big blower these days?
Huh, bummer. I thought it was just a standard GM 4 popper?They don't make the Titan 875 anymore.
Yes, how can we forget. A popular, now defunct, manufacturer was defying physics, pulling DOUBLE the cfm of some of the others. Turned out TWO machines were using the same waste tank.I know Lee.

Time and lack there of. Every minute of every day is spoken for including weekends. I rarely have down time and I don't just mean work. Plus I did have dreams of turning this thing over again but that idea died when the hour meter died. The pump is now leaking and the exhaust diverted quit working. May be sooner than August.Gene, remind me..why are you waiting to install that 870?

Remember also in a previous post in this thread I posted the secret to this setup working so well; the dual hoses going from the blower to the waste tank and the 4 hose barbs on the recovery tank. That opens up the entire airflow spectrum. My 30 years of cleaning, testing, designing and building ETM's, tinkering and testing some more, led me to discover all of this which I am willing to share with whomever wants to listen. I would go on a bit about my dual wand ETM and how great it works, with it's dual high-pressure pumps and patented circuitry, but I know not one of you is going to believe me there either.
By being able to dual wand properly with a 45 blower any carpet cleaner will now have an awesome CC TM without having to break the bank buying a larger machine. They will save fuel and weight driving around all day long, not to mention the efficiency of cleaning all day long with dual wands and the best APO I've ever seen or used.
That's why I've said I wouldn't trade this 30 year old machine for a brand new one, because I don't know of anyone who has a 45 blower TM that will dual wand properly like the one that I have, and one that has an APO that will go for weeks of daily use without any attention to it's filter system.
I challenge one of you MBer's who have a 45 to modify your TM so you can see - "That's what I'm talkin' bout!"
Read head. Freckles. Carpet cleaner. J sounding name. Close enough.Yes, how can we forget. A popular, now defunct, manufacturer was defying physics, pulling DOUBLE the cfm of some of the others. Turned out TWO machines were using the same waste tank.
That was my oldest son, Jeremy, who now lives near you in Dayton. He's in OSHA there.
Your machine does so well because you've carefully eliminated wasteful restrictions and maximized the cfm of your blower, not by defying physics.
The 45 blower has a 2.5" intake port and discharge port. I put a galvanized T on the blower intake, 2.5" x 2" x 2". From there I ran two separate 2" hoses into the waste tank, to match the area of two 2" vac hoses going out to dual wands. Two 2" hoses have more area than a 2.5" hose.I believe what you say.. I had a prochem that I had to create new vacuum ports for because it was so constricting.
I am going to be tinkering this summer with a TM build. I was going to use a 31 hp liquid cooled engine with a 47 blower.. Can you PM me pics of how you have the hoses going into the waste tank.. for what I am reading you have more than one going from the blower to the tank?
Where do you hook up the second vacuum hose for your tech to use, does it go straight into the waste tank or do you have a splitter. I made a Y splitter and split it off 50 ft from the main vac line.
Do you think the size of the wand matters? I know everyone preaches the 2 inch wand but my 1 1/2 inch wand would scream more than my 2 inch wand. Right now I have a Maxx 450 and a Maxx 470 .. I tried to dual wand but was only able to dual clean if the other was upholstery.. even then if the uph tool wasn't locked it would kill my suction.
Thanks..

There are two 2" hoses going from the recovery tank to the TM for the dual wands - no splitter. From there we run two separate 2" hoses inside all the way to the wand for cleaning. The Lift and CFM scream. You have to have the two separate hoses from the blower to the tank or it won't give you enough vacuum.
I have two of the vac hoses going into the tank going thru the lid (blower to tank), and the other two at the top side of the tank. The two going to the blower have filter screens on them.
With this setup you don't have to fool with the 2.5" vac hose. The 2.5" hose is just too cumbersome, and really not necessary when running the hoses into the jobsite.
I prefer the 2" wand because it has 4 jets, and does a better job recovering the water with the 2" tube, but when we dual wand, we use one 2" wand, and one 1.5" wand, for a total of 14 flow.
We can dual wand with 300' of vac hose total (150' per side) with very little vac loss. You can even lay one of the vac hoses open on the floor and still clean with the other. I'll do a video soon showing the Lift at the end of 300' of vac hose, with the other wand off the floor. A few mentioned they can't believe there would be any lift to speak of when dual wanding as I describe.
I thought about that, but I don't think that is a restriction because it is right on the blower. I have had it this way for way over 10 years now, and have more vacuum than I really need for cleaning with dual wands.Very interesting, I never thought of modifying it straight from the blower. Do you think the T that you used restricted it a little bit.. What are you thoughts of a custom welded pipe with 3 barbs coming off the blower going into a waste tank?
