The Polaris QT Blower is every bit as powerful as it is quiet. You can enjoy the soothing effects of powerful, invigorating bubbles in your spa without excess equipment noise. In fact, independent laboratory tests prove it's quieter than competitive blowers.

A patented thermal relief valve automatically compensates for temporary rises in temperature so the blower motor doesn't get hot enough to reach the shutoff point. This means longer, more relaxing, uninterrupted service.
