SilentMaster Central Vacuum

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.
