Metal Air Bottom Mount Blower 1 HP 240V 3.8Amp made by Polaris 1-521-03

Polaris aboveground, residential blowers are specially designed for installation in noise-sensitive environments.
All blowers are equipped with a patented thermal protection device that prevents overheating from excessive back pressure or mechanical problems. An auto-reset feature automatically restarts the motor once it has cooled. The unique thermal valve also compensates for temporary rises in temperature so the blower motor is less likely to reach the shutoff point.
