The motor uses Infinity brushes rated for more than 1,500 hours, while 710 airwatts, 151.9 inches of water lift, and 137.1 CFM provide the core performance figures for this central vacuum power unit.\u003c\/p\u003e\n\u003cp\u003eIts hybrid filtration system gives homeowners two operating choices. You can use a disposable triple-layer bag for convenient debris removal, or operate bagless with the included True HEPA self-cleaning filter. The True HEPA filter must remain installed in either configuration and filters up to 99.99%.\u003c\/p\u003e\n\u003cp\u003eThe 22 L bottom-load canister is made from lightweight, rustproof aluminum and is designed for removal wherever the power unit is installed. Dual side air intakes make the unit adaptable to an existing piping network, and the system fits standard 2-inch outside-diameter PVC piping meeting ASTM F2158.\u003c\/p\u003e\n\u003cp\u003eSoft-start\/stop technology helps reduce the stress of starting and stopping the motor, while a three-second delay helps clear the hose and piping after cleaning.

It is also a practical replacement option when an existing central vacuum installation uses standard 2-inch outside-diameter PVC piping and has suitable electrical service.\u003c\/p\u003e\n\u003cp\u003eThe SD-710-22SF is not automatically the right choice for every installation. The quieter 65 dB SD-659-22SF offers 659 airwatts, 144.9 inches of water lift, and 135.8 CFM, while the 750-airwatt HD-750-22H offers 146 inches of water lift, 141.2 CFM, and 65 dB. A larger 32 L unit, such as the SD-710-32SF, may be preferable when more canister capacity is important and the installation has room for it.\u003c\/p\u003e\n\u003cp\u003eThe central vacuum power unit must be installed indoors in a weather-protected, well-ventilated location with 6 inches of clearance on all sides.
