Product Details

Master Flow Gable mount attic ventilators are a great choice for exhaust ventilation. They are the easiest power vent to install and won't detract from the appearance of your roof. They remove the greatest volume of hot and/or humid air from your attic, saving you more in energy costs than any other type of ventilation. Two models available (PG2 and PG3X).

    I purchased two of these from HD for my 2400sqft roof to replace the 25+ year old Broan fans that were starting to wear out. To see how many and which models you'd need based on the pitch of your roof, go to the Masterflow website. They have a sizing chart in their documentation/manual.I want to keep my attic space from heating up and making my central AC system from working harder.I will say I notice less vibration with this unit but it still is faintly noticeable. I put rubber pads under the mounts at each point where it connects to the metal shroud. I also put them on the 3/4" strapping I used to secure the mounts/fan. I read comments from people here and believe the advice helped. I think I'm going to also try the 8" wide foil insulation wrapped around the shroud and use long tie wraps to hold it down. I'll see if that helps with the sound and vibration even more.These mounts were not the same ones from the Broan and I knew I'd have to use strapping or 2x4 to secure them. I did that. My plywood is 1/2" with cedar shakes on outside siding and then I used 3/4" strapping. So I used 1-1/2" coarse rock screws to secure everything. I pre-drilled the holes as well so the wood would not split. I tested the unit by turning the thermometer all the way counter clockwise but I will leave the setting on 100 or 105 degrees which is good for this region. I'll follow-up with a post this summer once they kick on by themselves via the thermostat. So far, so good. They are lighter in weight than the old ones too.

    Makes a big difference in the attic. It's much cooler.

    I found out that my old attic exhaust fan wasn't working, So I went out and purchased this unit and coudn't be more pleased. Installtion is very simple, one person can actually do it depending on where you are installing it in your attic. The price was fair and hopefully over time I would recoup what I payed in energy savings. I would reccomend this product to a friend.

    Installed fan in attic gable vent. Made nice box to seal fan to vent (No leaks). Attic is relatively small (30' x 20' approx). Fan functioned properly and so did the controller. The issue was the gable vent had an insect screen which restricted the airflow. Ran several temperature measurement experiments over two weeks and the best I could drop the attic temp was about 2-3 degrees F. I live in New England where bugs and bats are common, so I did not want to change to the gable vent that blows open with the fan breeze. These vents did not have a bug screen and I could only assume after a few years the vent would not fully close and allow bats and bees to get in. I removes the system. Again the fan worked fine it was the installation. I took a lot of steps to reduce the transmission of fan vibration to the wall. The use of foam and rubber was used at all mounting points. The noise level in the house was low and acceptable.

    My husband and I were able to work together to install the motor and fan parts of this. Could not use the housing and bracing bars as our old one was 17", not 15" as this one turned out to be, though home depot doesn't accurately give the specs on-line. Easy to install, but you definitely need two people.

    After climbing through 50' of attic hunched over and installing the fan, it doesn't work. Remove thr piece of garbage and crawl 50' out. Go to store turn in bad fan, get 2nd fan, repeat process.

    I have had 3 of these fans. I should have stopped at number 2. The fan blades become loose and slip and wobble on their hubs. I have tack welded 2 of the blades to their hubs after they became noisey. One is holding and one, even after being welded, totally detached from it's hub. The blade is a pressed and crimped on the hub and because the fans are not balanced the vibration is causing this failure. If the current fan fails again. I will look for a fan from another company. I will never buy this brand again.

    Over all a good fan after we finally got it installed. The first fan we purchased the controll box fell into pieces when we took it out of the box so we returned that one and inspected the next one prior to leaving the store. There was no real sound dampening pads on the mounts so once installed the vibration ran down the wall pretty bad, and that was the wall of 2 bedrooms, not good. So we made some rubber pads to place under the mounts to absorb some of the sound and snugged it all down and it was all good from there. The only regret we have is that it does not have a humidistat on it like our old fan, just hope this one lasts longer than our other one did. Just be sure to inspect the contents prior to leaving the store to save yourself an extra trip back to the store.

    Fan was very easy to set up and install. I used rubber pads between the brackets and the board to quiet any vibration. I also used rubber pads between the washer/screw heads and the brackets and between the board and the studs. The fun has a low hum from the motor and that's all I can hear. I mounted the thermostat on the stud next to the fan and tapped the wiring into an existing light wiring that we no longer use. Yes, I'd recommend this to others...matter of fact, my brother in law is going to get one for his place and we will be installing it tomorrow.

    Replaced identical attic fan- previous one lasted 11 years in South Florida. Installed additional rubber pads to suspend from the structure to minimize sound(vibration travels in structures throughout the house). Fan is very quiet, unable to hear it inside the house now. Thermostat is set to 95- running fan keeps house very comfortable and compared to 2500W Trane, is a big money-saver and will extend the life of the A/C as well. Overall, a good value. Very satisfied customer.

    I made this purchase based on the review that the fan is pretty quiet. I think it is very loud. I work shift and the first day it kicked on, it woke me from a dead sleep. It sounds like a big work truck is outside your house. The guy who installed it said it works great, that the attic is cool but it is loud. You need to be able to mount it some place over a room you do not use.

    Installed the vent fan and had no problems. Thermostat is easy to set. Waited to install until temps were cooler so it hasn't really kicked on but a couple of times. Like the extended warranty period.

    I mounted this fan on the gable in the attic. We have ours set to come on at 85 degrees and I am not exaggerating that my air conditioning is running 1/2 as much and the house feels great all the time. This is going to save me a lot of money. The fan itself is all metal and has rubber grommets to isolate the fan itself from the round enclosure so it's not noisy. It comes with a 10 year parts and 5 year labor warranty. It's not loud. To hear it I have to put my ear on a doorframe in a room under the fan to tell whether it's on or not. I'm satisfied with the quality and function of this fan and think it is well worth the price paid. The best of many I have considered.

    The installation itself was not difficult, but the vibration noise when running was more than expected. The housing itself, did not fully enshroud the opening either. What was intended to vent my house attic was used instead for my garage.

    I installed this fan a couple of days ago and so far so good. The thermostat is adjustable and I set mine for 100 degrees and checked it with a IR heat gun, it works within the +- 5 degree range. I did get a little vibration in the unit, not that I could hear it in the house, but in the attic there was a little noise. I wrapped the outside of the shroud with adheisive backed foil/foam insulation (available at HD), problem solved. This fan really moves a lot of air compaired to the solar model it replaced. I chose this model over the PG-2 because the warranty is significantly longer. It's been cooler so I can't comment on the overall temp and effect on household temperatures.

    I bought this fan to go with the manufacturers louvered aluminum gable shutter. Installation and wiring of the fan itself is pretty starightforward, as long as you understand a little bit about framing construction. I've never seen a gable without a stud running down dead center. If you want your fan and vent centered, you're going to have to cut and reframe. Make sure both your junction box and the thermostat are set above the vent in case something gets stuck and rain blows in. I put mine on a circuit with a GFCI breaker. Make sure the back side of the thermostat is open to the air and not against a wall. Also make sure your soffits are clear; the incoming air has to come from someplace.I set the thermostat at 105, as recommended. The fan comes on late morning, then goes off around 5 PM. It's very quiet, but I made sure it was solidly mounted, with nothing near it to vibrate. The difference in my attic now as opposed to before installing it is amazing. The upstairs is also noticeably cooler. Not much more I could ask for.The manufacturers warranty is great. It's 10 years on the fan itself, and they also include 5 years of labor coverage. Make sure you keep your receipt.I would have given the unit 5 stars, but they lost points because the instructions are so poor.

    It took about an hour to install...very easy.It was probably 110 degrees in the attic when it was installed...I set the thermostat on 105 degrees as recommended in the instruction manual. The fan would not come on...I lowered the thermostat to 70 degres before the fan came on.The fan will never cut off...mid January perhaps!The thermostat is totally useless.

    It was relatively easy to install, if you have at least medium handyman skills, you will be fine. And it runs quiet, I don't hear it inside at all, and it is not obnoxious sounding at all outside by the pool. It does seem to run a lot, from about 10AM to at least 9PM. But this is Alabama. The house is not dramatically more comfortable (maybe a little), and the A/C does not seem to run much less, if any. But the proof will be in the KW used, I suppose, and its only been installed a week or so, too early to tell.

    I added addiitonal rubber washers to the mounting legs. It runs very quiet - more so than expected! The difference it made on our 2,000 sq. ft. home is unbelievable! A/C runs considerably less than before! Fan turns on before noon and off at around 5:00 pm in our south Florida attic. I couldn't be more pleased!

    Once I had one that worked I'm happy with the fan. Made two trips back to Home Depot to replace broken fans. First fan was missing parts and second vibrated so bad it would shake the exterior wall where the fan was installed. I had no issues returning defective fans. Home Depot was excellent with the exchange.

    Easy to install, works well, the only negative is that it is louder than I expected. The fan works well and does the job.

    Installed myself rather easily and it works very well. We have a split level and the fan is installed on the gable vent nearest the lower level so it does create a lot of noise when near the fan. Location. But, it is powerful and I expect. Some noise.

    Adding this power gable vent has really lowered the temperature in our attic area. It has also help lower the temperature in our home!

    Replaced the old long-lasting attic with this one. Installed easily, runs as it should, fairly quiet. I like the long-warranty, too.

    A nice product at a good price. It keeps my attic from getting too hot. I love the thermostat especially! Very nice, and well worth the money spent. Recommended for all.It's one hard thing to install, however. I had to get a professional to put it in. It would have taken me days to figure this out and many cut fingers. So the main thing is you have to know what you are doing to get this installed correctly.
