As the central component of a central vacuum system, the PurePower 550W Power Unit enables you to clean your entire home, even including your indoor air. This next generation model features better suction and quieter operation with ULTRA Silent Technology. With a 1-stage motor that delivers 550 air watts of power and 120-foot water lift, the PP550 Power Unit is robust enough to cover up to 7,000 square feet of space.

What Is A Central Vacuum Power Unit?

As the heart of a NuTone Central Vacuum System, the Power Unit is a motor that wall-mounts away from the main living area, like in your garage or basement, and connects to special tubing run throughout the walls of your house. This tubing connects the motor to in-wall outlets installed at convenient locations in different rooms. All you carry around is the vacuum hose, which plugs into and receives power from these outlets.

About The PurePower 550W Hybrid Power Unit

As part of the PurePower series, the PP550 unit features a powerful thru-flow motor whose sound is effectively muffled by high-performance sound-absorbing material. The motor is nearly silent when installed in a basement or garage.

The PP550 model collects debris in large 6-gallon 2-ply disposable filter bags (sold separately), that slides over a removable collection pail. The bag is made of electrostatically charged filter, capturing particles down to 0.10 micron at 85% efficiency.

Additional Features Of PurePower Motors

All NuTone Central Vacuum Power Units provide superior soil removal, filtration, efficiency, and minimal carpet wear. The PurePower unit features a multi-directional vacuum connection for easy installation even in small spaces, and provides a 6-foot power cord for versatile power connections. A wall-mount bracket is included for simple and secure mounting.

When it's time to replace the debris bag (typically every 6 months), the Power Unit's oversized handles will make the process quick and easy. Simply release both latches on the sides of the unit, grab the handles, and remove the pail, which holds the bag. The full bag slides off easily, and the new bag slides on. Just put the pail back, close the latches, and you're finished!

Today's Most Efficient Way To Clean!

With their powerful motors, NuTone built-in central vacuum systems pull dust, dirt and allergens from the living environment more effectively than portable vacuums, trapping them within the filtration system of the power unit, away from the living environment. The central vacuum system can also be used more effectively to "power dust" furniture and living space by removing the dust from the living areas rather than just moving it around. And unlike conventional vacuum cleaners, NuTone central vacuum systems are a long-lasting built-in convenience that actually adds value to your home.
