Central Vacuum Power Units

Silent Master is MD’s premiere power unit line. Its performance and value are unequaled and backed by a 12-year transferable warranty that even covers normal wear and tear. Silent Master’s dual-motor units boast high levels of suction and airflow simultaneously which sustains powerful cleaning throughout the system. This higher level of performance is coupled with longevity as the two motors can operate at lower RPM as compared to single motor models. Models ranging from 495 to 900 air watts provide deep cleaning power for any home. Silent Master’s Tru-Seal® Microfiltration features a closed bag, 5-ply microfilter that connects to both intakes and the utility valve and holds 8 gallons of debris.

Many homes will find Flo-Master the brand of choice. Excellent performance in combination with aggressive pricing makes this model line everything a homeowner desires in a central vacuum. All Flo-Master models offer quality Ametek motors, quiet operation, a utility valve and a pre-installed air-relief valve to eliminate overheating the thru-flow motor. Flo-Master is built with 18 and 20 gauge steel, powder-coated inside and out, and features the highest quality electronics. Most Flo-Master units are backed with a 10-year warranty for long term, trouble-free operation. The highly efficient Tru-Seal® Microfiltration keeps the thru-flow motors clean and cool.
