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.

Replacement Power Vent Motor for PR-1, PR-2, PG1 and PG2 Series is rated 4.1 out of 5 by 233.
Rated 2 out of 5 by from Consider it a consumable Razor blades are designed to wear out after a certain number of uses and so too are these motors. I recently purchased a new residence and the seller had two of these motors on hand to replace the two failed ones up in the attic. I placed a thermo probe in the attic prior to replacement - temp reached a high of 141 deg F. After replacement we are down to 102 deg F. As others have said, you need 2x 7/16 wrenches and an allen wrench (mine required 5/32 - odd). The bolt/nut removal for the housing is easiest when you have one socket drive and one closed end wrench. The fan is fairly loud when running but I can't hear it once my attic access door is closed.

Rated 3 out of 5 by from Regular replacement I have four individual fan roof vent systems between my house and breezeway/garage. When I replace the motors I put the month and year on the end. Due to the poor bearing system in these motors they seize up after approx. 3 years. I keep an extra one on hand. Just had another seize up last week ( a little over 3 years old). It appears that they have cornered the market on this motor, can't find a replacement from another manufacturer at this time. Several years ago I purchased the same motor at Home Depot for approx. $35.00. The price just keeps going up!! Soon you may find the whole gable end unit on sale for less that the motor.

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.

Rated 1 out of 5 by from Frequently Fails. Why do they continue offering this junk?! From reading some of these reviews, I guess I should consider myself fortunate: I have only had to replace this motor 4 times in 10 years. Of the 4, two of the motors were serviced by a retired motor tech/electrician (the thermal protection failed in both cases) before I decided to buy another. Curious that a motor made to cool hot attics fails due to over temp! As another reviewer stated, I would gladly pay double for a motor that last. At least they should back the quality of their product by offering a prorate on the NEXT replacement! Home Depot, PLEASE OFFER a quality alternative!

Rated 1 out of 5 by from Lasted less than a year. Don't check the fan too often and when I did was very surprised it was not working. Had replaced the motor last summer. The original (Leslie Locke motor / unit) lasted for years and years. Motor finally gave out. Why oh why didn't I have it rebuilt! GAF purchased Leslie Locke at some point and called them Flowmasters. The original Leslie Locke units were quality and lasted. The cheap replacement motor lasted less than a year. Sure, I'm going up to change it out in August and take it back to HD for a refund. The motor is junk. Guess that's all we can expect to purchase now that we don't make anything here anymore except burgers. Too bad ...

Rated 5 out of 5 by from FAN-tastic I purchased the PR2-HI22 in 4/8/2001 and installed a lighted inline switch in the closet to turn the unit off in the winter. The light install is attached to the dead side of the wire/switch, so when switched on there is a light indicator. I have not replaced the motor but purchased this replacement motor, just in case it is needed. I feel most who have had issues set the trip level too low which results in higher fan operation. Although, if you follow the instructions it recommends 105° F, I set the thermostat to 118° F. I also did my best to make sure the thermostat gets plenty of air flow when the motor is operating. Hope this information will assist those who have had issues.

Rated 5 out of 5 by from Easy installation as replacement This is the second motor replacement I have used this summer and found that I could easily remove the old motor from the holding brackets by using a socket wrench and combination box wrench and securing the new motor in its place was easy and it is the exact right size for a perfect fit. Wiring the new motor was easy also as it hooks up to the thermostat the same way the old motor was connected, just make sure to unscrew the flexible conduit on the old motor and install it in the connector on the new motor before connecting to the stat. All in all a good product that was easy to install and worked like it was supposed to.

Rated 1 out of 5 by from Get the bigger motor. I bought the 1/5 hp, model PVM115, instead of this under powered one. When the fan motor on my model PG2 fan went out, I read the reviews here. Then I noticed that there weren't any reviews on the 1/5hp motor for the PG3. It isn't carried in stores either. Is this because it doesn't have to be replaced as often??? So for only $10 more I bought the bigger motor. The dimensions are different, but it fit fine. It wouldn't slide into the sleeve of the housing, but removing and reconnecting the straps did the job. Works great, and hopefully will last longer than the one season that the smaller one did.
