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 210.
Rated 4 out of 5 by from Maintenace is the key to long life The problem that I run into most often is that the fan motors bushings dry out and treat excessive load on the motor and as a result it overheated and damage is it over long time to the point where it sometimes can burn out the motor or the starter for the PSC motor. I recommend that owners perform maintenance. Remove the vent cover, apply a few drops of a light machine oil at the point where the motor shaft enters the motor. It will “weap” into the brass bushing. Do this every spring

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.

It did fit ,and is turning the 10" fan quietly. I left one brace loose and one band bolt just started to have some stability. With great difficulty, I wiggled the motor,/ fan attached up to the band straps, attached the third brace, and started the second band bolt. With motor in final position, tightened both band bolts. The original Leslie-Locke motor lasted about 18 years, and a replacement (Certainteed from Lowes) ran 18 years. I hope the one -year warranty on this Master Flow motor is not its life expectancy!

My original Master Flow power vent motor died after 10+ years, so I bought this one to replace it. Should've listened to the other reviews. New motor lasted just over one year (and it doesn't run in the entire winter season, so total run time of +/- 6 months on this thing) and it's DEAD already. Total piece of garbage. A year later I'm leaving this review as I'm shopping for another replacement. Looks like I'll give the 1/5hp PV115 a try instead, as others have suggested. Fingers crossed it's not as bad as this one. Time will tell.

This product has improved greatly over the years, I know because it some years only lasted 8-12 months. I have this particular model in my Green House and it has been 4 years since I replaced it. It is difficult given the location, to switch out. Normally the fan blades somehow become unbalanced, leading to an eventual obstruction causing the mortar to burn out. This time it was just the motor that stopped working. Overall, I despite having to repurchase and reinstall; no one else has a comparative product.

Having never replaced a fan motor before, I was a little leery as to whether I could actually do it. First of all, plan on changing out the motor in the early morning when it's cooler if you're changing it in the summer as i did. It turned out to be pretty easy. You will need the correct size hex key to remove the fan blade from the old motor to the new. Once I got it installed, I was pleasantly surprised that this new motor was much quieter than the old. I'm very pleased.
