If Hayden is your go to central vacuum then you will be thrilled to hear of 3 new central vacuum power units: Zircon, Titanium, and Platinum. All three units are Hybrids which means they can run with or without a bag. A bag is recommended to extend the life of the filter and motor.
The units are made in Canada with a 3.8 gal dirt bucket made of 18-20 gauge stainless steel. If you choose to use a bag, the units use a 3-layer electro static bag and an inverted cloth HEPA filter. Each unit is equipped with 1 motor and has 1, 2, or 3 turbines (fans). They are rated for homes up to 10,000 square feet and all three units are backed with a 5-year warranty.
These new Hayden units can replace another Hayden and virtually any other brand of central vacuum.
