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, built from steel, and entirely powder-coat painted to ensure durability. Strategically selected for optimum performance, motors are installed at the base of the unit. This design keeps the vacuum unit cooler, resulting in optimum compaction of debris and less wear and tear on the system. Less wear and tear means less maintenance, which adds up to a longer lasting system.
