It's been a while since I've bought any vacuums, and I'm looking to add a couple more central vacuum units. I don't use them with pipes, just attach a utility valve to the in-take and connect the hose. Using them this way makes for a very powerful canister cleaner. So, here they are, probably going to get them in the next couple of weeks. First is the little giant.
And then there's the power house, nice name for a central vac unit.
They both come in 4 or 9 gallon models, I figured I would just get the 4 gallon one, though I wonder if the 9 gallon version would provide better airflow, not sure on that. Once I get these I will have 10 central vacuum units in my collection.

alternative to little giant

Instead of the little giant, I may get this one instead, it's the Purvac L170, it's a 700 air watt unit. Interestingly, the Purvac units are also made by Drainvac which is the company that makes the units I listed in my first post. It's interesting that they make vacuums with their own company name, Drainvac, but also make units under the Purvac brand name. Why not just make everything under one brand name, or maybe it's common for companies to do something like that, not just with vacuums but with other things, to make products under more than one brand name.

I saw in another thread that you have a Purvac Barracuda which is very similar to the

If you're looking to add something different I'd like to suggest the Allegro MUA75 Zenith? Why? It features a HUGE 8.4" motor it has a max amp rating of 13.8 the flow rating and suction ratings are also quite good.

I'm mainly suggesting this cause i've had my eye on one, I just don't know anyone who has one :P.

Drainvac recently updated their lineup. I'm not sure what's new about them. Sadly their Booster models have been discontinued, I've been wanting to try those out to see how powerful they really are like the DV1R18 for example since Drainvac isn't common in my area.

I don't know about Purvac, they don't have their own website so it's possible that Thinkvacuums owns that brand.

My DrainVac AC2605-C from 2005 is still going strong.
It was removed from my old house and replaced my parents old central vac unit from the 70's :)

I've always been a fan of...

The Linday manufacturing brands.... That would be Astro Vac, Valet, Vacumaid, and Imperium... all the same stuff.

purvac web site and 8.4 motor

Purvac does have a web site which I will include here. I actually have a central vacuum unit that uses the Ametek 8.4 motor, the vacumaid SR800, it's a bagged unit with 713 air watts and it uses the Ametek 8.4 bypass motor. Yes, I think Lindsay manufacturing makes good vacuums, they make the Vacumaid model I just mentioned, I also have their garage vac pro, that one uses a 5.7 inch motor and has a hose in-let right on the unit.
I don't think Purvac is a think vacuums brand only but I could be wrong on that, yes I do have the Barracuda model and it's awesome. When you go to their site, it defaults to being in French so you will need to switch to English.

I wasn't aware you had an 8.4" unit already. Doing a search I see snippets here and there on the forum but overall what do you think of it? Are they loud compared to other central vacs? Does it out perform the others?

Post# 409082 , Reply# 8   5/4/2019 at 07:57 (338 days old) by n0oxy (Saint Louis Missouri, United States)        
8.4 motor

It's not any louder than most other units, and it is quite powerful. The unit is fairly large in order to have enough room to hold the large motor. The one thing I don't like, and this is more related to the unit itself rather than the motor is that there is no manual override switch on it. So, since I use all of my units without pipes I had to connect a short wire from the utility valve to the wire terminals on the unit and sometimes these tend to come loose. With my other units, I just put the valve on the in-take and use the override switch, much easier. I think that's something all units should have.

If I had a 240 volt outlet

So, I went ahead and ordered the powerhouse unit that I mentioned in a previous post. I really wish I had a 240 volt outlet in my apartment, if I did, I would definitely get one of these units, I can only imagine what connecting a hose directly to one of these and using them without pipes would be like, probably incredible power.
First we have the Drainvac Twin Turbo.
And then there's the Purvac Killer Whale.
Both of these sound like awesome powerful beasts. If I ever do own a house, I'm definitely getting a 240 volt outlet.

According to UPS, I should get my new Power House central vacuum unit today, so excited. I have a utility valve ready to be put on to the intake so I can use it without pipes. Nothing like opening a new vacuum, I don't know about anyone else but I think opening a new vacuum is awesome, there's just something special about it.

Looking at the specs for the Drainvac Twin Turbo Central Vacuum System, did you see how much power it draws?

15.5 Amps @ 240 Volts = 3720 Watts (3.72 kW)!

That'll certainly "dim the lights" hahaha!

I did get a laugh at an obvious error in their product description though.

"The Twin Turbo was first designed to be used for commercial applications with its crushing max 1,436 air-watts (suction power)."

Airwatts is NOT suction power. Airwatts is the product of suction times airflow and that quantity divided by 8.5 for a specific diameter hole. But most people definitely won't catch that. At some point, I'd love to test central vacuums systems...

new poer house is awesome

When I got home today, my new central vacuum unit was waiting for me, it definitely lives up to its name. It has found a nice home next to my night stand in my bedroom, I hope it is happy there, it seems to be. It's very quiet but very powerful. I did not use any pipes, just put a utility valve right on to the intake and connect the central vacuum hose, it's very powerful, one way you can test the power of a vacuum is to see how fast it can spin a turbo brush, this thing spins the rug rat turbo brush very fast, it's a very good central vacuum unit. I know many central vacuum companies use Ametek motors, Drainvac uses motors from Domel and they seem to be just as good.
Regarding the 240 volt central vacuum units, yes, that does draw quite a bit of power, if I ever live in a place that has one of those outlets, I am definitely getting one of those units, that would be awesome. If I get any more units, I will need to also get more utility valves, I just used my last one for the new powerhouse.

Ahhh I see now

That website you've posted about Purvac was international, no wonder I couldn't find it. But there's still no local retailer near me, in fact they don't have one here in the states other than Thinkvacuums. If I were to pick which Canadian made unit company I would use in my home, I would pick Cyclovac since they're the easiest to find and do business with in my area.

Canadian central vacuum companies

A lot of central vacuums are made in Canada, Cyclovac, Canavac, Drainvac, Purvac which is a brand made by Drainvac, and Duovac.
I don't think Cyclovac sells their units on line, or if they do, none of the major on line vacuum stores sell them, but they sound really good. There are no stores in this area that sell them either that I know of.

120 volt two motor units

These two systems are interesting, they use two motors but run on 120 volts, and the amp rating is about the same as a one motor system. I'm wondering if this is per motor or if the motors used are just smaller. I think the highest amperage you can get from a 120 volt outlet is 20.
First is the Drainvac Turbo.
And then there is the Purvac Great White
Both of these sound awesome!

Drainvac Viper

This unit also looks awesome, I'm thinking these units use flow through rather than bypass Domel motors. Supposedly bypass motors last longer but flow through motors seem to offer more power, it's interesting that they can get this much power with just one motor.

Cyclovac is only exclusively sold through dealers. They also make for several brands including Riccar and Simplicity but what I like about Cyclovac the best is they offer more models to choose from. They also give you an option of choosing which 3 filtration modes you would want to have whether it's bagged, hybrid, or cyclonic.

Aqua Air used to be made in Canada but they moved the production here in the states. And ACV (All Canada Vac) was sold here for a period of time, they even made units for a US company labeled as "Mountain Central Vacuum Systems", but they left the US market.

Not all Cyclovac units would give 3 mode options. The compacts for example are bagged only and some of the commercial models can be used for water filtration.

another Canadian company

I think there is another Canadian central vacuum company, they are called Alegro or something similar, I'm not sure if they just sell accessories or if they actually make units.
The closest Cyclovac dealer is several hundred miles from here, I'm guessing they are not as common as some of the other brands. MD is another company that chooses not to sell their units on line, personally I think this is a mistake but it is each company's choice.
Yes, with several Cyclovac units, you can choose your filtration method, I would choose bagged only, that is the best way to go in my view. The first central vacuum unit I got, a Beam 275 was bagless and I hated emptying it, I was almost to the point of being willing to give it away. I was able to convert it to use bags and this is far better. I still don't use that unit very much because it is by far the loudest unit in my collection, even with a muffler.

There is a brand that Cyclovac privately makes that is sold through online, it's called Galaxie. Unlike Cyclovac, there are less options to choose from and they can only use one filtration mode. Some are bagged, some are hybrid, and some are cyclonic.

Personally, I'd rather buy from a dealer. I don't trust buying new vacuums from websites unless if they were discontinued that I would add to the collection.

Luckily with Beam since they were recently bought by Nuera Air, all of their bagless models are now hybrid.

galaxie and beam

I had heard of Galaxie but I didn't know that Cyclovac made those. I knew Beam had been sold to the company that makes Duovac but I didn't know that they started making their systems hybrid. Many of the Beam units could be converted to use a bag, I converted mine, I did not like emptying that at all when it was bagless. Switching to a hybrid is a very good thing for the Beam brand.
I have bought several of my central vacuum units on line and have not had any problems. Actually the only ones I did not buy on line were my Beam 275 and my MD Flomaster M85. Speaking of MD manufacturing, I was looking at the specs for their newest models, they are a bit lacking. With their silent master line, they are only using 5.7 bypass motors, Ametek makes bypass motors in sizes of 6.6, 7.2 and 8.4 but MD doesn't make models that use those. Actually when it comes to getting the most power for the price, those Drainvac units are probably the best. the imperium brand also has really good prices, those are basically the same as the Vacumaid units.

a couple more units

Here are a couple more central vacuum units I am looking at. Not sure how many more I will get this year but I would like to get a few more.
First we have the Duovac Star.
And then there is the Galaxie ga-200, this one sounds awesome.

You might want to check with the plug on the Galaxie. I know with Cyclovac, some of the dual motor units come with different types of plugs for certain outlets like the ones that are used for either in the garage or in the basement. But I will say this, Cyclovac makes one of the finest systems on the market. If I were to pass on MD and had to choose on what my next option would be, I would pick anything that is made by Cyclovac. Mostly the ones that are sold through dealers.

The reason I wouldn't buy new vacuums online is because I wouldn't want to get into the shipping business. For example; If I were to get a part from a dealer, I wouldn't have to pay for shipping. Thinkvacuums requires consumers to pack up and pay shipping on defective items which is usually more than compare to what a dealer would charge, especially from the store that I worked at because we offered discount labors to anyone that would buy from us.

Okay those specs are fishy. A dual motor setup is either parallel which specializes in flow or Series which provides higher lift. I'm going to guess that they took each motor's specs and just added them together.

Central Vacuums are a huge source of corporate incest.... Meaning that there's about 4 plants that make 50 brands. A look through the accessories section will easily prove my point.

I've got a very mixed up system here, but it kicks butt... Nutone Inlets & Pipe, Imperium Motor, Allegro, Vacuflo and Nutone hoses......Lindhaus and Intertek power nozzles......and a bunch of other parts with no names on them. It still kicks butt.

Here's an example

blackheart's profile picture
In a parallel motor system your suction will be equal to what each single motor can create they are pulling at the same pressure but you do have a boost in airflow as you can see from this vacuums specs this appears to be the case.
I was going to pull up an example of a series motor too but The only one I can think of is an old Broan CV40...D? I think but the problem is I don't have specs for that. I can get motor specs but without machine specs they're kind of useless

Sorry for the double post I just came across this article from vacumaid

8 central vacuum motor FAQ answered by Ametek

4. What happens when two or more motors are connected in (air) series?
In this arrangement involving bypass motors, the working air exhaust from the first motor is directed to the fan intake of the second motor, providing for a significant increase in the vacuum performance at small orifice conditions with no appreciable increase in CFM. We don not recommend the used of two through-flow motors in a series connection as the heat from one motor is transferred to the second motors creating an overheated situation.

5. What happens when two or more motors are in (air) parallel?
This arrangement usually involves two or more motors mounted in the cover of a large container. Each motorís fan system is working from the same air space. In this case, air flow (CFM) is significantly increased at a large orifice conditions with no appreciable increase in vacuum.

This is what leads me to believe they just added the numbers on that Galaxie.

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.

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.
