MD G23 240V Dual Motor Central Vacuum Cleaner System

[robocleanlover]

I want to know if anyuhyuz knows about the MD G23 240V and seen it before. Also if anywuhnyuz have brochures of it with other models and brochures of hose sets and individual attachments for it, please do electronic copies for me. If anyuhyuz have pictures of the MD G23 240 Volt, please post them.

This is so far the only picture I could find of the MD G23 240 Volt Dual Motor Central Vacuum System.

The picture on the MD website at https://builtinvacuum.com/parts/modernday/motors-filters/ is correct and was the latest version of the G23 when it was produced. The nomenclature came about because "G" was the next logical letter in the series and the 23 stood for (2) 3-stage motors. When MD unitized their model numbers, this became the M965h2 which is still available today with (2) Ametek 117123 Motors The 240 volt version has always had these motors thus the original power stats were the same. Yes, It was a beast!!!

That looks like a late 1970s or early 1980s model E...the G23 didn't come about until the mid 1990s when the 116765 and 117123 became available (Grant please correct me if I'm wrong).

G23 will have a wider louvered bottom (though not as wide as on an SV or SVT, which used two 7.2" motors) and a darker blue color.

Here's one I serviced in the north suburbs of Chicago.

Quite a bit less common than the S5 (S900) and the older MD-built triple motor Air-Flo CFM3 units, which this one replaced.

You are correct that the light blue one was a Model E that would have had the 115334 in it. I had to blow the picture up! And the motorshell that flared into the base was from the late 1970 when it was made at Charlie Emdy's garage. Interestingly from the end of 1976 through 1984 I was doing a good portion of the assembly and likely built that unit! I still have the serial number log files with my hand writing if you can find the serial number. That log book went through our fire in 1984 and is still singed around the edges! Yes, the G23 had louvers that were almost even with the exterior of the can and yes, centralvacs 1928, the G23 obtained it's nomenclature in about 1994/1995 after Wayne Emdy passed away. It was mainly created to offer an alternate unit for the dealers who were not able to obtain the S3 Silent Master units that were proprietary.

Do you have a G23 Volt Dual Motor power unit you can do pictures of?

 

[centralvacguru]

That would be identical to our Model M965. But I believe we only produced it in the darker blue color.

Here's the cut sheet on it:

950 air watts. Geez Louise. Bet that thing spins the electric meter.

What about this MD SVT 240V Dual Motor Central Vacuum System Power Canister now? Can I please have a cut sheet of this one and other photos of the MD SVT 240V Dual Motor Central Vacuum System Power Canister as well?

 

[centralvacguru]

The SVT was created as a variation of the Model SV but we added the "T" at the end to differentiate it as having "Three-Stage" motors. We did not sell many of them in 240 volt thus we never produced a cut sheet in 240 volt but it have very, very similar stats. This white one was likely a "one-off" that we produced quite a bit after we stopped really pushing the product because it was so cumbersome to build. The 3-stage 5'7" motors were easier to work with and had better liongevity because the long shaft on the 3-stage 7.2" motor was a 10mm and would cause premature bearing problems,
Here is the sheet on the SVT in 120 Volts.

Thank you.

If the G23 240 Volt wasn't available locally and I had no choice. I would go with the MD SVT 240 Volt instead for the 19,800 mansion I am going to build with my money from my synthrock music I am going to produce and sing someday. I already got a Yamaha SHS-200 FM Digital Keytar Synthesizer, I'm going to get a wireless MIDIJet Pro USB 2.0 Transmission and Receiving System for it! I also plan on getting a white Yamaha Montage 8 Workstation Synthesizer. It's going to be wirelessly played by my Yamaha SHS-200.

Out of curiosity, is there a specific reason why you'd want to put a G23 or a SVT in your own dream home? Why not simply go with either a SilentMaster S900r2 or a Modern Day M956h2? They're easier to find from a local MD dealer, you'd get fresh brand new parts, and you'd get a warranty.

 

[centralvacguru]

I would agree with asking the question. The S900 has the exact same motors but in a radial exhaust instead of tangential exhaust, built on the same platform. You loose a little bit of performance but get 2-years longer of warranty and far quieter operation.. And panisonicvac is right that the S900r2 is far easier to obtain. We still make the G23 as our Modern Day Model M965h2 but rarely sell them. The S900r2 is $13.00 more retail than the M965r2.

I have an older SVT installed here at home. Actually, it started life as a Model SV, but since I noticed it had the same taller motor enclosure as an SVT, I replaced the motors with three stage 117507's. The performance is just a bit less than an S5 or S900 (which would be my go-to modern replacement) but I like the sound of the larger, slower-RPM motors. Not that I can really hear the unit anywhere except the mechanical room, anyway.

Because I love nostalgia. 240V Dual Motor Central Vacuum Systems for extra power and preserving older technology.

Would anyone know where I could find the inside of that brochure that Owen has linked with his svt. In New Zealand we have Kiwivac central vacuums and their kb range of machines. There is the kb which I do not know what motor it has, the kb2 with a single 117123, the kb3 with a single massive 8.4 inch motor. This machine has the same motor as the m715h2. The next biggest size is the twin motor kb4t with dual 117123 motors. the Kiwivac units have closed disposable paper dustbags and a comparably very short cloth support bag. I would describe the cloth support bag as a support to hold the base, They are only about 3-4 inches tall when expanded. below that there is a square of high density foam as a filter. When I met the owner of Kiwivac about a year ago he told me that we got MD silent masters in up until just a couple decades ago when someone came up with the idea of making the machines here in NZ.

I had never heard of Kiwivac. Neat looking machines. Definitely MD-inspired.

Here is the complete brochure. These were current when I started selling MD around 2005.
