Any of the central vacuums I have the motor is mounted on a rubber gasket ring-provide air seal and noise suppression. |

It's not really clear to me how the motor is mounted. If there is ANY metal-to-metal attachment of the motor to the housing, it will amplify the noise of the motor considerably. In the picture, it looks like there is a triangular shaped bracket that's missing the bolts to hold it down. Is that what's supposed to hold the motor?
Like Les says, adding pieces of felt between any metal-to-metal motor mounting would help, at least a little. That big empty cavity where the motor sits, anyway, could be lined with some kind of foam. Acoustic foam is what you want, but in reality, it's kinda pricey when any old foam will do. Next time you see someone throw away a couch, grab the cushions. As a matter of fact, I'm not sure what the muffler looks like, but you could make that yourself out of a coffee can and a bit of old foam. I've already made two air compressor mufflers like that. |

The motor and pull everything out of the vacuum tube. Get a pole urethane spray foam insulation. You could also spray something similar to think lining.
You could built a box and enclose the vacuum cut out ports and vents. Then at the top of the box vent and a vent at the bottom. Put small fans both sides sucking in cold through the bottom circulating through the top. |

But you could invest in a pair of good quality wireless noise cancelling headphones, for while you're working down there or something like the guys out on the tarmac wear at the airport! Just a thought. |

I hate being a wet blanket (well sometimes, but not trying to be here) but in all honesty, if you wanted a quiet unit, this one will likely never be able to meet your wants there. Also, this thing will get much louder over time, as these don’t use a filter, it’s a “true cyclonic” unit and all of the fine dust will be passing through the motor. This also means that you cannot run this thing exhausted into your basement or any other part of the house, you absolutely must pipe the exhaust outside of the house. Doing this will completely remove the exhaust noise from the basement, but still put a muffler on the exhaust, as the vent outside will be as loud as the exhaust was in the basement!

There's a reason why true cyclonic units uses a bypass motor. You would need more layers of filtration than converting the cyclonic canister to just using bags if you were to convert a thru-flow motor in a true cyclonic unit. And honestly I don't even know if the author in this thread has a dirt canister for either the P-225 or the S1600. What I would suggest instead is to get a DC800 bagged canister from Vacumaid that uses HEPA filtration. Otherwise that's one of the downfalls that I have seen from thru-flow motors is without extra filtration layers, the bearings and the motor itself can go bad quicker. Another thing too that I have found is the thru-flow motors do run much hotter than bypass motors.

One of the beauties with a true cyclonic unit is there are no filters to ever have buy, clean, or replace. And because they are required to be vented outside, you don't have to worry about all the dust and dirt that you would suck up being blown back indoors. I mean sure it's not like maintaining a bagged unit but I have found that if you use a trash bag to wrap around the unit to clean the debris off the screen like you would with a dryer lint trap. Then use that same trash bag to wrap around the canister tightly to empty it, let the dust settle down for a minute or so while the bag is still sealed onto the canister, seal the trash bag completely afterwards, and throw it away. I barely would get any dust on my hands. Another thing that I have found with Vacuflo's true cyclonic units is the screens doesn't get clogged as much compared to Vacumaid's. In all on honesty, I wouldn't hesitate to put in either a Vacuflo 566Q or a Vacuflo 760 in my own house if I wanted to go for a bagless unit.
I have an uncle who owns a MD Flo-Master F650t that uses a thru-flow motor and it uses a bag that costs like $10 per piece. I can confirm that it does get hot while running. But it is just as quiet as a top of the line MD SilentMaster S5 that uses "two" bypass motors. I don't believe all thru-flow motors are quieter than bypass motors. And who says you can't vent out a central vac that uses a bypass motor? I've seen plenty myself that do. Anyways, those are my two cents here. On a side note, Cana-Vac uses both types of motors for their units and they prefer bypass themselves. canavac.com/central-vacuum-motors...

I think Canada assembles one of the finest power units on the market. I really like Cyclovac. If I were to pass on getting an American made MD, Cyclovac would be my next choice to get. They have one of the best warranties in the industry! However I will have to admit, I'm impressed with the motors used on Drainvac. I think you could possibly get away with using some units that has a thru-flow motor if you switch from using bagged to bagless. But I think getting a cyclonic dirt canister for a bagged unit or just a true cyclonic unit would still be a better option to have. Cyclovac sells a cyclonic dirt canister and possibly ACV (All Canada Vac), the Canadian version of Vacumaid.
