What Makes the SilentMaster S900R Different?
The SilentMaster S900R combines the cleaning capability of two powerful bypass motors with a sound-conscious design. Unlike smaller single-motor central vacuum systems, the SilentMaster is engineered for larger installations where strong airflow and dependable suction are essential.
Its 8-gallon Tru-Seal closed bag system provides generous dirt capacity while helping keep collected dust contained during bag replacement. The durable steel housing, dual exhaust design, and flexible intake connections make it an excellent option for homeowners investing in a long-lasting central vacuum system.
