We stock the 4" I.D. hose for the larger blowers.

Larry, at the risk of sounding like an ass (again), I have to ask if you stock 4" hose why do you choke down so many of your "bigger blower" units of the shelf with 2.5"? :? Or was that someone else trying to convince me on a previous thread that 56 blowers only needed 2.5" hose from port to tank?

It's to put the blower under constant strain, so that it runs hotter and generates more heat for heat transfer. Most HX manufacturers use that principle. Some hide it better than others.

Yea everybody knows the reason they do it. It is bad enough on the exhaust side of the blower but to choke down a blower on the intake side is just plain ridiculous. I don't care who does it.
I thought maybe undersized intake plumbing was a cost cutting proposition, but hell if you have it in stock why would you short change a "big blower's" potential.

You guys need to really think about the Vac System as a whole.
The entire 2 ft. from the blower to our vac tank is insignificant compared to all the other restrictions in the system.
2.5" vs 4" for 2 feet will NOT be different on our flowmeter.
It is about the same difference as between 99.5' & 100' of 2" vac hose (that's 1/2% of the restriction)
The real restrictions we minimize are the:
1. Silencer (we now use a 6" x 36" model)
2. Heat Exchanger (ours has 19 1/2" straight tubes)
3. Waste Tank (ours has no baffles)
4. Vac Hose ( 2.5" or 2" depending on customer preference)
5. WandLip-Carpet Interface (Glides do help)
6. Vac Inlet Filter (we just built the 1st one with TWO 2.5" ports & ONE 2" port)
So which TM manufacturer is actually minimizing all of these vac system losses ???

Larry, You really need the guys from roots or sutorbuilt to teach you how to use a flow meter properly.
The closer to the intake the greater the restriction. The longer the hose run the more obvious the undersized intake will be.
The main question I have is what POSITIVE benefit is there in using 2.5" intake plumbing? I know you won't answer because the answer is NONE. I am giving up on you Larry. I once thought there was hope, but now I am convinced you are to entrenched in "the way you have always done it" to ever improve.
Do you honestly think that will help if you only have a single 2.5" intake from blower to tank :roll: ?
Cleanco has been doing that for years :shock: .
And they don't choke down the blower between tank and blower port.
And I have never seen pictures of one of their units posted on the net with the intake plumbing melted down and a complete vac system failure that was never explained.
Here is clue: 2.5" pvc is not a good intake choice for a "big blower" :shock: :shock: :shock:

The flow thru any vac system is dependent on ALL the restrictions from the carpet to the machine exhaust. Any lint filter is is a restriction.
It makes absolutely no difference where the restriction is in the system (except at the open wand end).
The silencer, HX design, wand & vac hose together are at least 200 times the flow restriction of 2.5" plumbing from the blower to the vac tank.
So where is the restriction to be worked on ??
Our blower intake fittings & exhaust plumbing is 100% steel (mostly stainless).
Here's a Vortex picture posted earlier (courtesy of Wizard), that shows their 4" (edited from 3"per Greenie) PVC plumbing quite clearly:
Notice the rubber reducing adapter on the right.

that is 4" off of a 4" port 5009 blower which enlarges to 6" at the tank.
this will be my one and only comment on this thread, there is much misinformation here, and engineer would have his eyes rolling back in his head at some of the justifications.

Feel free to start a new vac thread where you can post your thoughts on the contributions of ALL the various items in the vac system.
I would like to see it.
I do feel the 2.5" hose does make a significant difference, BECAUSE there is a hundred feet of length, typically.

I have to get ready for an evening of dinning and putt putt golf. I promise to comment more on this topic. I will address with practical description of each of Larry's numbered concerns.
I have yet to see an answer to my question concerning the positive benefit of using undersized plumbing IE 2.5" on a #5 blower.
I have said this before but it went unnoticed I guess, IF 2.5" INTAKE WAS ADEQUATE FOR A # 5 BLOWER IT WOULD COME FROM THE BLOWER MANUFACTURER WITH SUCH :shock: :shock: :shock:
