Will this fit the old PR2 model with three leg mounting from the bottom of the motor?

I have the old PR2 model attic fan with three-leg mounting from the bottom of the motor. The new mounting is the four-leg bracket. Will this motor be compatible with the old mounting scheme?
Asked by: Wei
I just called Master Flow and they said this will fit my 3-leg frame. Since it is simply a band that goes around the motor it doesn't make a difference how many legs it goes around.

Customer Reviews

Replacement Power Vent Motor for PR-1, PR-2, PG1 and PG2 Series is rated 4.1 out of 5 by 243.
Rated 4 out of 5 by from Working just fine, so far! I am writing this review only a few weeks after I installed two of these attic fan motors. I say that because I really don't know of the quality yet but the two motors have been working flawlessly through some of Georgia's hottest temps so far. I originally had two attic fans installed about 10 years ago. Those motors both stopped working this year. I think one of the problems that caused the original motors to go out was the fact that the original installer only cut half a hole out of my roof, thereby reducing the air flow and I would assume decreasing time on the motors. I had to end up cutting the holes out and the replacement took a few hours each. I broke it up two different mornings because the attic got so hot. I have seen other reviews that say that these motors are cheap and unreliable. I don't know. I hope that they last as long as the other motors did. So far I am really pleased with them and I can tell a huge difference in the temperature inside my house on a hot summer day.

Rated 3 out of 5 by from Used to replace DOW-136-0-40 XIN power attic vent fan motor I replaced my DOW-136-0-40 XIN motor with this one. If you do this, you may need to make a few mounting modifications, but it does work. The 4 mounting bolts, I had to undo all 4 bolts(thru-bolts), and reverse, to attached to the tranglular mounting bracket that was attached to the DOW motor; however, 2 bolts lined up with the triangular bracket, 2 did not, but a couple quick drill holes in the bracket solved this. Also, the Shaft on this Home Depot item is shorter than the DOW. Once installed (before hooking up electric), turn the blades of the fan, mine just slightly touched the L-brackets on the fan housing from the roof. So I just bent the fan blades up just a bit to allow clearence. The old fan motor had a steel sheath on the wire, this just twists off the old, and onto this new one. It's working now. With all that said, we will have to see about quality. I gave it average based on what typical HD items last, which is not usually great. So take that for what you want. Time will tell.

Rated 4 out of 5 by from These motors require maintenance every 2-3 years. Have used this roof vent system for 30 years, replaced a couple of times when the plastic dome, not the metal one deteriorated in TX sun. The motor has only bronze sleeve bearings that require periodic cleaning and lubrication. Have looked for, but never found a ball bearing motor for this application. To cut down on dust entering the shaft end of the motor, cut a 2 inch diameter leather or rubber circle, punch a 7/16 hole in the center and slip over the shaft between the motor and fan. One can get 15-20 years out of a motor with some regular care and lubrication. The new motor is a capacitor run motor drawing 1.6 amp instead of 3-4 amps. A motor with sealed ball bearing and thrust bearing would solve the problem.
