SilentMaster Central Vacuum Systems- For the health of your home.
Why choose a Silent Master?
There are a lot of things that make an M.D. Central Vacuum an excellent investment for your home. From the vacuum brush all the way to the motor, we think we've designed the best and most cost-effective central vacuum system on the market. Let us show you step by step why we think our system is the best in the industry.
To achieve maximum performance out of any attachment, you must maximize the airflow dynamics of the system. That means the connection of the brush to the wall inlet must be designed at an optimal diameter for maximum suction power. A four-inlet system with approximately 80 feet of 2" pipe to the motor and a 30-foot x 1 3/8" hose on the carpet will produce its effective performance at the 1 1/8" air opening size in the power brush. While most manufacturers ignore this law of airflow and only offer units with high water-lift statistics, M.D. has specifically designed its SilentMaster S2, and S5 to peak their performance at the 1 1/8" opening size for maximum airflow.
The next step in ensuring maximum benefit from your central system is using the proper motor. Maximum airflow dynamics is achieved with two motors operating in parallel, not in series, and cannot be achieved with a single motor. Due to the expense of the motors, most two motor units are made from 5.7" motors as opposed to the larger 7.2" motors. Single motor systems peak their performance at a 3/4" to 7/8" opening and have lost almost half their power at the larger 1 1/8" opening. That's why we design our entire system to take advantage of maximum performance specifications in every component. Read Vacuumology for a better understanding of airflow dynamics.
Also, due to our motors being on the bottom of the power unit, we have the coolest running motors. Power units with the motor located on the top pull in cooling air from the highest, hottest point of the unit. Our cooling intake on the bottom provides the lowest, coolest air. All of this adds up to greater longevity of the power unit.
M.D. has designed the most extensive filtration system to protect the motors. An inherent limitation in competitors cyclonic systems exists in that the motors should not have ANY dust going into the impellers! Please take a moment to review our filtration analysis, to see how we filter without having serious suction loss. Our paper filters are the largest in the industry, have the highest air-permeability rating, and the lowest initial pressure loss. As a side benefit of this filtration, our units do not need to be vented outside in most applications.
Add to all these benefits the fact that our SilentMaster® units -
To back up our claims, we provide a 6-year warranty on all electrical components, see warranty. Don't be fooled by "Lifetime Warranties." Read the fine print (if findable). Make sure it covers wear and tear!
- have a patented noise suppression system that puts it below normal conversation level.
- feel so much stronger! That's because it's made of 18-gauge steel compared to most vacs using 20 or 22 gauges.
- are powder-coated inside and out to insure decades of use.
- are the easiest to mount on the wall, and
- are the only to offer both left and right entry of the debris.
MD's technical support is "par excellance." No other company offers you the technical education on each and every facet of the industry. Their website alone, at over 5000 pages, addresses more issues than any other vacuum company in the world. Also, because of their exclusive distribution policies, they have retained the best installers of central vacuums in more than 40 countries.
Now that you are armed with the important facts, we hope you will agree that M.D. central vacuum products will clean your home better than any other vacuum out there. We welcome any comparison!
