That is beyond pathetic! I can't really tell in the photo you've taken, but if I had to take a wild guess, I would think that "Hoover" motor is a single stage Ametek Lamb motor or equivalent. It's hard to imagine anyone thinking that such a small motor in a central vac would ever hold up to that kind of useage! That just goes to show you how companies are taking the cheap way out of making their products now! Build it as cheaply as possible and sell it for as much money as you can possibly get out of it.
Thanks for posting this, I had seriously been toying with the idea of putting a central vac in the house, but if I do, I will be looking out for these cheaply made machines! | ||

But is the one on the left not a "by-pass" motor as well? The type used in wet & dry cleaners. Is there a need for that type of motor and as reason why a none-by-pass motor will suffice? | ||

I am Really shocked at the size of the hoover but equally shocked at the size of the motor that comes from the canavac central vac. That motor is a triple stage tangential motor, It is widely used in portable carpet cleaning machines. Triple stage meaning its has 3 suction fans. and tangential meaning it has side discharge, you can if you want massive lift hook up another one to suck through the exhaust of the first one. What shocks me is that a central vacuum would use just one of those motors, most central vacuums here in SA use two of the big motors like the one pictured below or a actual vacuum pump, I have never seen a central vacuum that uses such a small motor ( yet alone the tiny one found in the Hoover )

Yes it is shocking but that said I just saw a prototype motor that is the size of my hand but will outperform most 3 stage vacuums. We get a few here, cfm, Nilfiskalto, vacu man, centra vac, Electrolux Beam, hygenevac, to name a few, all that I have worked on have had twin motor design with either two 3stage motors or two of the bigger ones, My central vac uses a vacuum pump but I hardly use it as I prefer a vacuum in hand | ||

The one I have on my central system is 1.8kw 220v, although I have seen them go to the size you mention, They are awesome and make the coolest sound when they are on, almost like a Subaru flat four engine, My one is not very noisy , no nosier than a quiet vacuum but the one i service a week ago sounded like a rocket. What I like about them is the fact that they have such huge airflow and lift, with central vacuums normally you loose so much airflow due to the friction loss in the internal piping in the walls, This thing generates 450cfm at the pump which means at my furthest socket from the unit I am still getting 180cfm
