The rugged all-steel construction of the Polaris Metal Blowers has been an industry standard.

The unique, 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.

All Polaris Anzen bottom exhaust metal blowers are U.L. Listed for both indoor and outdoor use. U.L. Listed models conform to electrical codes throughout the U.S.A.

The thermally-protected blower motor shuts off automatically under excessive operating temperatures for protection against motor damage. Equipped with auto reset, the thermally-protected motor restarts automatically after cooling.

The built-in check valve adds protection against blower damage from water surges.

Polaris blowers are covered by a one year, limited warranty.
