The MD APX 650 Central Vacuum Power Unit delivers an impressive combination of strong performance, quiet operation and tremendous value for money. Producing 650 airwatts of cleaning power and rated for homes up to 6,000 square feet, it provides more than enough suction for most small to medium-sized central vacuum systems.
Its compact design makes the APX 650 especially well suited for installations where wall space is at a premium, including utility rooms, closets, basements and smaller garages. Despite its space-saving footprint, it offers the capable cleaning performance typically associated with much larger power units.
The APX 650 is also an ideal replacement for NuTone CV-350, CV-353, CV-400, CV-450 and CV-750 central vacuums. Its similarly compact dimensions make it a practical fit in locations previously occupied by these units, while its powerful motor provides the suction needed to restore strong, dependable performance to the existing system.
An easy-to-change disposable bag keeps collected dust and debris securely contained, making routine maintenance cleaner, faster and more convenient than emptying a bagless system. Its quiet operation further adds to its everyday appeal, particularly when the power unit must be installed near the home’s living areas.
Whether selected for a new installation or as a space-conscious replacement for an aging NuTone central vacuum, the MD APX 650 provides excellent suction, straightforward maintenance and dependable performance in a compact, affordable package.

Its large eight-gallon Tru-Seal disposable bag provides generous capacity while keeping collected dust, dirt and allergens securely contained during removal. The bag seals automatically when removed, helping prevent the cloud of dust and debris commonly associated with emptying a bagless central vacuum.
MD’s exclusive Dual-Stud Mounting Bracket secures the F650 across two wall studs for a stronger, more stable installation than a traditional single-stud mounting system. A built-in utility inlet also allows a vacuum hose to connect directly to the power unit, making it especially convenient for cleaning garages, basements and the area surrounding the machine.
With its high-capacity filtration, secure mounting system, convenient utility inlet and exceptional transferable warranty, the MD F650 is a thoughtfully engineered central vacuum power unit built to provide years of clean, reliable performance.
