MD · SILENTMASTER · STEALTH
From installed MD power units to compatible hoses and tools, we help homeowners understand service and upgrade options for their existing systems.

Central vacuum equipment sold under MD-related model families can vary by vintage, motor configuration, filtration setup and accessories. Knowing the exact model is the fastest path toward understanding service and compatibility.
Before ordering a part or replacing the machine, we recommend confirming the model plate and determining whether the issue is electrical, mechanical or within the hose and piping.
