Thank you for contacting MasterFlow ... No, This application is not recommended for our fan. All of our motors are air cooled open frame which are not compatible with this application, as this could pose a fire hazard. Please call Technical Services at 800-211-9612 with any additional questions.

1000 CFM Power Roof Mount Vent in Mill is rated 3.0 out of 5 by 25.
Rated 5 out of 5 by from Cool! I live in hot, humid, Houston. My house is two stories with open areas over the "greatroom," living room, and entry. In the summer, one could not venture upstairs between 1 p.m. and 8 p.m. because it was so hot. I installed this power vent and now the upstairs stays the same temp as the downstairs. The upstairs airconditioning unit even turns off in the evening. So, I am a lot cooler and I expect to save on my electric bill. This is easy to install. I just put it where there was an existing vent (even when the fan is not running, it still vents) so I didn't have to cut a hole in the roof. The instructions are excellent and easy to follow.

Rated 5 out of 5 by from Great value. I bought this vent for a small green house. It was straight forward to install. I just followed the instructions and was careful handling it because it's kind of easy to damage before it's instlled, bulky. I stand right under it while it's running in the green house and it's about the same noise as my box fan on medium, much quieter than I thought it was going to be. Thermostat works great. I used a $3 can of spray paint and made it brown so it didn't show up as bad on the roof. I thought it was a great value and I am very happy with the outcome. Oh, the local store had it for $69 on the shelf and when I told them it was on the web for $56 they price matched with no problem.

Rated 5 out of 5 by from Noticeable difference! We hardly run AC now When it started to get hot last summer, we had been running the AC for only a couple days before I installed this unit. The difference was immediately noticeable and we didn't need to run the AC until the peak of summer heat, about a month later. I have an old 1200-sqft home in near-costal CA with no insulation and this fan eliminated most of my AC needs. The fan is quiet; I don't hear it unless I'm in the attic. The salesperson at HD said I could use a bigger fan and it would be even better, but I don't believe this is true -- get the appropriate size and make the ventilation changes suggested in the instructions (namely, plug original ridgeline vents to ensure air comes in via lower soffits). In fact, I want to install a whole house fan now but they are too powerful (1/4hp while this is 1/10hp), so I'll use one of these and fashion my own -- seems like having matched fans at the ceiling and roof is a good idea (and cheaper). I gave it 5-stars even though it's only been in service for one season; if it breaks within 5 years I'll come back and change my rating to 1-star.

Rated 1 out of 5 by from Dead in 2 weeks I bought this unit to vent an attic of an interior townhouse. The installation was very easy and within a couple of hours the fan was running. It did a great job of keeping the second floor comfortable but after 2 weeks I noticed that it was hot again. I went into the attic to find that the fan was no longer working. I checked all the electrical connections and found them in good order. I then tried by-passing the thermostat but as it turns out the motor is blown. Guess I will have to wait to Monday to see what the company is going to do about it. Apparently I am not the only one this has happened to. I just wish I would have read the reviews before I bought this unit. Save yourself the trouble and don’t buy this fan.

Rated 5 out of 5 by from Power Roof Vent It works as described. It is quiet and the attic and house is cooler. No attic space should be without one. It will pay for itself. Wish I had bought it sooner.

Rated 1 out of 5 by from attic vent very poor I purchased and installed one of these last July,it worked great for eleven months then the motor burned out. I couldn't find my sales slip so naturally I just went back to the store and purchased another one and hooked it up. While hooking it up I also checked all of my wiring and connections for wear or anything else that may have caused the first one to burn out, all seemed to be fine. I finished my installation of the second one and fired it up, it sounded good ran fine and I was really pleased with it for three days then it quit running. Again I checked everything and installed yet another unit. I checked again for any problems with the wiring or the installation and found all to be in order. I returned this one to Home Depot getting an exchange unit. This unit went in the same way without any hitches except that after everything was finished and seemed to be running fine, it quit. This was after about thirty minutes of running on a cool day, nothing was hot, even the motor didn't seem to be hot, it just quit. No I would not recommend this product to anyone unless you just enjoy doing repeated installations or just need the practice. I must say that except for the first unit that I failed to keep the receipt for, Home Depot did exchange units with me on the second one and as of right now, I'm taking the third unit down to see if I can exchange for something different that will work better than these last three have.

Rated 2 out of 5 by from Motor Just burned out... Guess I am just adding one more log to the fire. I installed two of these last Summer. Worked great, quiet and installed easily. However, the motor burned out on the one this past spring. The other is still working. Thinking about taking the burned motor apart to see what happened. if its just brushes or a condenser, it might be an easy and cheap fix. Yes I could call the company and see what they can do, but I didn't keep the box, instructions or receipt... so I'll take the $70 stupid penalty.

Rated 1 out of 5 by from Motor failed at about 5 years. Lots of work to replace it. Made in China naturally. Find a brand made in the U.S. Appliance motors should last 20-30 years. Installing a roof vent really helps reduce the temperature of the house and reduce the A/C usage. Installation by a private guy was about $150. Just don't buy this brand. Going to look for the receipt amongst the large box of HD receipts.
