a couple of new central vacuum units

motors in series and parallel

I'm not sure on this but I think that most two motor systems use a parallel configuration which would, at least in theory increase the airflow. However, the airflow will still be restricted by the hose and pipes so I'm not sure if anything is really gained from that configuration. I would think a series configuration would be better, this will increase the suction, also known as waterlift. Apparently this configuration can cause motors to fail sooner since the exhaust from the first motor is being fed in to the second one.

going to get the Drainvac Viper

I've decided to get the Drainvac Viper, this will be my 10th central vacuum unit for my collection. Since I use all of my units without pipes, I will also need to get some more utility valves. I attach them to the intake of the units and then connect the hose, so the utility valve basically functions as an adapter to allow the hose to connect directly to the unit. This will be the most powerful unit in my collection, I'm not sure how they get this much power using one motor but it should be awesome.

I think that for me one of the BEST vacuums is the Eureka Mighty Mite, I have had this one for about 4 years and It seems to running with no problems, I should also add that if anybody wants to buy a vacuum they should visit https://devices4home.com/best-bagged-vacuum/
. It is full with valuable info on vacuum reviews although there are plenty more vacuum sites out there, just do your research before buying.

These are great vacuums and I like them , I must say, I have seen the reviews online and they seem to be worth the buck, there are tons upon tons of vacuums out there on review sites but I think that for me at least the Dyson cyclone takes the cake

Viper is awesome

I got my new Drainvac Viper, it's awesome, very quiet and delivers on the power. I'm actually surprised that more companies don't use Domel motors in their central vacuums, I think they are quieter than the motors made by Ametek.

more central vacuum units

I'm hoping to get a 240 volt outlet installed in my apartment at the end of this month, not sure if this will be possible yet since the apartment is on the second floor and the breaker box is in the basement but I have an electrician coming to take a look. If I get the new outlet, there are definitely a few 240 volt units I'm going to see about getting, and here they are.
The unit I am most interested in is the Drainvac Twin Turbo, based on the specs, this is probably one of the most powerful units on the market.

Then there is the Duovac Distinction, one interesting thing about this unit is that the CFM is a bit low at only 106, that's very low for a central vacuum, especially a 240 volt two motor model.

The last 240 volt model I am looking at is the Galaxie GA-240.

Of course, if I can't get a 240 volt outlet installed I will have to skip these units but hoping for the best. Actually, if a new outlet cannot be installed, I'm going to ask them to check if all of my outlets are on the same phase or if some of my outlets are on the opposite phase, if I have some outlets on each phase, I can get a converter that will combine the two phases and this will provide 240 volts.
I'm also looking at a few more 120 volt units, these are probably some of the most powerful 120 volt units that are available, the Drainvac Viper would definitely fit that category and I already have that one.
First we have the Galaxie ga-200.

Then there is the Drainvac Turbo.

And last but not least is the Duovac Star.

I have decided that, for the foreseeable future, when it comes to expanding my collection that central vacuum units are the way to go because they are the most powerful cleaners available. I know there is anew model Rainbow coming out some time soon and I had thought about trading in my E2black for the new model but I'm going to hold off on that. Even with a trade in, the cost of the new model Rainbow will still be at least the price of one of these central vacuum units and I know for sure that the new Rainbow will not be as powerful as a central vacuum unit.
