            After 3 motors this one has met the output speed of my swamp cooler. I have a 4800CFM swamp cooler and it requires a 1hp motor to sufficiently cool my house. Hessaire needs to revise their specifications for motor horsepower to 1hp not what they currently recommend.

            My swamp cooler motor went in thermal protection mode just as my sister came to visit. We quickly went to Home Depot and found the replacement motor. It took 15minutes to swap pulleys, install the motor and start cooling the house. It nice and quiet now.

            Just installed it, worked out of the box. The test will be how long it lasts.

            After only 2 days of using this motor it stalled. Now it won't spin without manual assistance.

            The motor fit, it doesn’t make much noise and it works.

            Two speed motor runs OK on high, but makes loud singing tones when on low speed. Cost me uninstall/reinstall substitute time and time returning it to HD. Big time waste.
