Description of Polaris Metal Spa Blowers 1 hp to 2 hp.

The Polaris Metal Blowers are comprised of a rugged all-steel construction with a bottom exhaust. They are equipped with a patented thermal protection device that prevents overheating from excessive back pressure or mechanical problems. The unique relief valve automatically compensates for temporary rises in temperature so the blower motor never gets hot enough to reach the shutoff point which means longer, more relaxing, uninterrupted service.

These residential blowers are specially designed for installation in noise-sensitive environments.
