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.
