What is the most powerful central vacuum?

[centralsweeper63]

I was looking at some central vacuums for a large house, then I got distracted looking at triple motor central vacuums. I know there are filtex, thoromatic and airflo triple motor units. I know there is a copy of a filtex/ central vacuum international unit that sells a single, double or triple motor unit. They all have 7.2 inch motors! I know it was a three letter abbreviation, though that is all I remember. I was also intrigued by massive dual motor units ( E.G. vacuflo 960, cyclovac 7515, vacuflo db10max, etc) If you have experience with any of these beasts I would love to hear about it.

Filtex. Wow, there's a name from the past. They used to make household canister vacuums in Los Angeles right after WWII. The bodies were made of the same material pegboard is made from. Now the brand is used for a central vacuum? Is it the same company or did somebody revive the name?

The Vacuflo 960 has since been discontinued, so is the CycloVac 7515 but they do make a 7525 today. From your list, I'd recommend the CycloVac. You'd have the option of having it either in parallel or series, can be used as bagged, ton of power, and one of the quietest central vacs I've ever heard of at least for a split system.

The Filtex name was bought out quite a few times over the last few decades and hasn't been used for central vacuums for a few decades in the USA. When they were in LA they used to make a few parts for MD and vice versa in the early 1960's. Even Lindsay Mfg trademarked the name early 2000's but since abandoned it. Filtex made units similar to MD in the 1980s including a (2) 7.2"-motor unit and a 3-motor unit. MD's original (2) 7.2" motor unit was a split system with the motors being the "DV" for "Dual Vacuum" and the "ST" for "Separator Tank". When the two were put into one unit it combined the letters making it our Model "SV". At this time, for our strongest unit, we recommend our Model S900 which has the same motors as the older S5.
