Central vacuums have historically had far greater performance than any portable or shop vacuums. The friction loss in the tubes has proven to be quite minimal as long as a quality filtering system is employed. Top-of-the-line portable vacuums such as Shop Vac’s would have about 65 Cubic Feet Per Minute (CFM) whereas our standard Model S2 would have 183. The tubing system is to be completely sealed to allow maximum suction through the entire system. Each bypass motor has it’s own cooling fan that draws air from around the motor to cool it; so there would be no need to add additional holes in the piping system. Central vacuums have not normally been rated in PSIG but it would be around 13-15 on some of them. Lamb Electric is the major manufacturer of vacuum motors in North America and the one that we have represented for almost 50 years. They are on the NYSE and make excellent products. The motors have actually a series of fans attached to the end of the rotating shaft. Fan structure is quite critical to achieve the correct waterlift and CFM for the intended use. Hope this helps you out. Please feel free to reference our website with any additional questions.
Thankfully, you have our signature top-emptying vacuum tank that will never be damaged when the filtration is not maintained. For your information, here is the Owner's Manual for Modern Day. You will find bag changing, replacing, and buying information there too. If your bag is full of dirt it can weight as much as 50lbs so you'll have to scoop out a lot of it to begin with. Getting new attachments will take your cleaning to the next level as well. Your system is universal so it can use any of the tools, kits and hoses for Modern Day. If you have a carpet consider an electric kit. Simply changing the bag and buying a new kit will take you to a whole new level in CLEAN.
With the MD filtration system, there is nothing that can get clogged so much as to burn out the motor. You have done everything that is needed for a complete filtration cleaning. Let us know if you have any other questions.
At MD Manufacturing, all our hoses are compatible with your MD whole house vacuum system. You may also consider a new complete hose and tool set too, especially an electric one if you have any wall to wall carpet.
We highly recommend any of our mid-line central vacuum models. They will all have better power than older systems and the price is affordable. We also recommend our electric attachment kits for deep cleaning. The main vacuum units are sold through local independent dealers so purchase both as you find a dealer through the Dealer Locator.
The electric kit, especially Stealth, will make a HUGE difference in cleaning and will last a very long time. The belt has a lifetime warranty! You don't need to change anything in the system, just buy any electric kit with the 8ft Cord/Pigtail option. The hose, on the wall end of it, has an attached electric cord that plugs into a nearby electrical outlet. You don't need to plug it in if you are not using the electric head and if the outlet is too far use a small extension cord. The wires are hidden in the lightweight hose. We're confident they will be very pleased. Here are the Electric Kits for Modern Day Vacuums.
As the manufacturer of Modern Day whole house vacuum, we have everything you need on this page Replacement Bags and Filters for Modern Day Central Vacuum Systems.
Model B2 works with Electic Kits and Air Kits. They are all compatible with your system, but one would be best considering the flooring in your home. If you have wall-to-wall carpets an Electric Kit is our recommendation, but if the majority of your home is hard floors then you can save some money with an air only hose and tool kit. Start here for buying a complete central vacuum kit for your home.
You can find wiring diagrams and motor replacement instructions for all the Modern Day models on the replacement motor page for Modern Day.
This vacuum head should spin really good and slow down slightly when on the carpet. If it doesn't then change the filter first. Test the vac directly from at the main vacuum unit with and without the hose using the manual switch on the right side bottom. The Turbocat can be on its last legs. We are glad to here the vacuum system itself is working well.
