MD Manufacturing's Central Vacuum Units

M.D. Manufacturing, Inc. is a Name You Can Trust

Take Advantage of MD's Customer Friendly Central Vac Units

MD Central Vacuum Units are designed and assembled in the USA to ensure quality, power, and durability. Motors are strategically installed at the base of the unit to keep the vacuum unit cooler. A cooler unit results in optimum compaction of debris and less wear and tear on the system as a whole. Add on the fact that they are built from steel and powder-coated inside and out, and the result is a system that requires less maintenance and is longer lasting.
