Retrofits ALL 8 & 12 GALLON UNITS including ALL Silent Master, MD, Modern Day, Flo-Master, and Air-Flo Vacuum Units.

Convert your dirty, open top, filtration to a complete dust and debris encapsulating, hypoallergenic, fully concealed filtration system.

It’s easy to upgrade to MD’s Tru-Seal Microfiltration System — the new standard in all top-emptying 14″ diameter central vacuum power units, including all 8 & 12 gallon systems. The Upgrade Kit includes 2 Tru-Seal Microfilter Bags, a new and improved bag adapter, and perfectly mating support bag.

TRU-SEAL BAG. The highly durable, Tru-Seal disposable filtration bag is a 5-ply microfilter that captures debris down to .3 microns. At 8-gallons, Tru-Seal has the largest trash capacity of any disposable residential central vacuum bag on the market. The side connections of the bag slip onto a Tru-Seal Adapter. The front utility valve connection simply slides onto the backside of the utility valve neck. If any connection on the bag is not used simply leave the included dust cap attached.

TRU-SEAL SUPPORT BAG. The Tru-Seal Support Bag must be installed in place of the existing blue support bag for proper fit and strength when the Tru-Seal Filtration system is being used. This support bag stays in the unit and the Tru-Seal Microfilter disposable bag fits properly inside it. This support bag fits into all MD, Modern Day, Silent Master, and Flo-Master power units no matter the height or previous filtration type. Sold individually. Diameter is 13-7/8 inches. Length is 13.5 inches.

TRU-SEAL ADAPTER. The new and improved bag adapter fits the Tru-Seal Microfilter bags and replaces all previous curved adapters when upgrading to the Tru-Seal Filtration. Use one for each side intake port, not for the front utility valve. Includes a round, black, foam gasket.

Note: If using both intake ports you will need to purchase an additional TRU-SEAL ADAPTER.

Simply follow the included instructions to install the new microfilter bag system.

Why upgrade? The Tru-Seal Microfiltration System features three connection points which allows debris intake from the front utility valve and both side intakes. The new bag is easy to install and change, while it’s encapsulating design and locking caps make disposal very sanitary.

COMPATIBILITY. Replaces all HYPERFLOW 721H-5 and 720H-5 Bags as well as EnviroCare MD Central Vacuum Bags MD814, MD814L. All 14” wide units, no matter the height or name can upgrade using the Tru-Seal Upgrade Kit. The Tru-Seal Microfilter Bag was implemented into production in all of MD’s branded vacuums on March 1, 2017.
