Suck Factor Over 9000!

CV locations and venting.

There's two places that people generally install their CV motors.

#1 Basements
#2 Garage

Basement/closet installs are usually vented outside
Garage units are usually not vented outside, but may be.

The Imperium is so quiet, I could put it anywhere.... the Nutone it replaced was best off in the basement or garage where it could make the noise it wanted to.

The 4 types mentioned..

Bagged

Filtered (inverted "self cleaning bag")

Cyclonic

Water Flushed (Self Cleaning)

Most people will be happiest with the bagged... the dirt is crushed down in the bag, it holds lots, and is easily replaced. The secondary filter is foam or screen, and gets washed on occasion, but 99% of the filtering is done by the bag.
a 6gal bag lasts MONTHS.

Filtered has this weighted inverting filter that is supposed to dump the dirt in the bucket when you shut it off. You'll be cleaning this whenever the suck factor drops.

NO THANKS... I'll stick to bagged.

Cyclonic is what it sounds like, but since it fluffs the dirt, you'll be dumping the bucket more often.

The Water/Self cleaning is sort of rainbow style... it uses water to wash dirt down the drain... there's a net to catch big pieces that would clog the drain. Aquavac and Drainvac are the two I know of in this style. You can shampoo carpets with this type CV.


Mine is installed in the basement, and vents outside.

When my house was built in the 70's, it had a Nutone system installed. I replaced the Nutone motor with the pictured Imperium above. The "Suck Factor" is off the charts. The Vacuflo type "Crush Proof" hose can withstand all the sucking, but just barely. If it's not straight, it will tighten its loops with the vacuum pressure, and you can just tell that there's enough power there that the hose is feeling the stress. When vacuuming a hard floor, the hose will lurch strongly if the airflow is restricted suddenly by a rug. Still it holds up ok. Before I upgraded to the Imperium, the Nutone didn't stress the hoses too much.

My three FAVORITE things about having a CV

1. Tremendous suck power
2. No Smells (since it vents outside)
3. Less Noise...
Plus, it's not heavy, and the long hoses make it easy to get into all the areas.

open and closed bags

The open bags are a bit messier to empty, but they do provide better airflow. The MD units can be converted to use closed bags though. I have a flo master m85, nice unit, well made, I just stuck with the open bag to get the best performance, but it's personal preference. I think the dirt devil central vacuums are made by HP products which is the same company that makes the vacuflo brand. When it comes to vacuflo, I find their prices very expensive for what you get, you can get better performing power units at a lower price. Yes, the claim that those filters clean themselves is a joke. I had mentioned that I had a beam unit in a previous post, before I converted it to use bags, dust would always stick to that filter which will decrease performance. When I installed the bag adapter, I removed that filter completely, the bag provides all filtration now.

I have 2 central units now

My original Vacuflo 466Q is true cyclonic when I dump it in the woods there is NO dust cloud as people keep saying, no dust anywhere in the garage, on my cars, on the unit or piping even on the vent outside it is clean. It is quiet hence the Q but I did have a muffler on it because my neighbors complained it was too loud when I'd use it at night but I said screw it & took it off let em suffer!!

The Beam Serenety 2725 has a bag filter that is not bad, machine, garage, piping all clean too and this one is very quiet when it's running w/no muffler on it, but there is a dust cloud when I dumped it but the bag does not look like the one in the video, that one should have been replaced years ago. You can tell it was not taken care of & proper maintenance was not performed as mentioned in the handbook.

Even though they say no venting is required on some of them I would still do it to make sure the area stays clean & everything goes outside. I have tried to purposely clog mine but the suction us too strong along with the correct piping that was installed in the home long after it was built. I also have a canister separator that attaches to a different hose that you can pick up 4 gallons of water in plus the auction is incredible on it. It is restaurant grade not the smaller plastic ones they have now so if I ever have to pick up water I don't have to hunt for a wet vac. [this post was last edited: 3/1/2017-21:16]

interceptors and venting outside

I actually tried an interceptor, did not have much luck with it. Lost a lot of the suction because the hoses would not connect properly, the interceptor was designed for central vacuums and I was using a central vacuum hose. The one I had was the metal one, attached to a small cart. Interesting that the beam unit you have is very quiet, mine, which is a beam classic model 275 is very loud, even with a muffler. Without a muffler, you wouldn't want to be in the same room with it, it's unbarable.
Regarding venting outside, here's another article from the same web site, they seem to not really be in favor of it, although I think the article is a bit paranoid, but take a look and see what you think.

Central Vac and noise...

Seriously, try one of the Imperiums... QUIET!... Plus major suckage.

If you REALLY

Want to see something, Mike Hays has 2- 2 motor Beam units in his basement hooked up in tandem to a Sppencer outlet and a full set of Spencer tools...UNBELIEVABLE!!

My MD Silentmaster has the open top "Hyperflow" bag-the best way to handle these is like a Compact/TriStar bag-replace the bag when its a little over half full.that way you can close the neck of the bag over the dust as you pull the bag from the tank.The vac shop once had a service call on an MD central unit that used this bag."No suction" was the complaint from the owner.What had happened was the bag was so full the cloth bag was pressing down on the foam after filter so hard that the motor intake was blocked.the bag had over 60 pounds of dirt in it.For me these bags last about 6 months -then I replace them.I have another MD central unit that has the closed top bag-smaller at 5 gal capacity.Its equivelant to an MD 650.In the VDTA new I read about in a vac shop trade book-they are going to offer a closed Filtrete bag that can be used with 8Gal or 12Gal MD units.This could be an answer.The new bag can also be used with the main inlets or utility inlet.The present closed bag only allows you to use the main inlets.I asked the MD dealer near me to order some of these when they become available.Would love to try them.also would like to see if they will fit my 650 unit mounted on the janitor cart.This newcomer has become another favorite!So Kirby and NSS have some company!
