Polaris QT Quiet Spa Blower 220V - 2 HP. 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.
