This is a 1600 CFM Energy Efficient Power Attic Gable Mount Ventilator with a 2.1 Amp thermally protected PSC motor, a galvanized steel flange, and an automatic thermostat. It mounts easily in the gable of your home, behind existing louvers or any other gable louvers of your choice. It will provide ventilation without modifying your roofline, or when roof-mounting is impractical.

  • Keeping your attic cooler and well ventilated will prolong the life of composite roof shingles and other roofing components, and help protect the roof structure itself
  • 1650 Cfm ventilates up to a 2500 sq. ft. attic
  • Included adjustable thermostat allows the fan to run only when needed
  • A cooler attic will keep you home cooler, reducing costs of air conditioning and wear and tear on your cooling equipment
  • Equalizes temperatures inside and outside the attic, helping prevent weather-induced home deterioration
  • As an exhaust vent, this fan requires a minimum of 792 sq. in. net free air intake airflow areas to perform safely and correctly

Rated 4 out of 5 by Best I could find for the money, so-so value, does the job. in the research I found that many people had some concerns and as it turns out, they are correct. I would love to talk to the company and offer some help. 1. The bolts heads are just wrong. they are shouldered heads and should be flat pan heads. They will hit the blade. Bad design. I purchased two nuts with a lock washer between them so they do not vibrate loose. 2. Pay attention to thermostat. The directions showed using the air hole to wire in the power. That is wrong, needs to be unblocked to sense the temp. Mine was received defectived and the replacement had a second hole on the side of the box with wires going to the motor. once replaced it works fine. 3. I built a framed half circle gable mount since that was what i have in my house and I did remove the center 2x4 that would have blocked the middle of the airflow. I then built a structure to span that center structure to the outside 2x4 frame studs ( love that snow weight) and the 2x4 frame with double 3/4 inch plywood makes a stable mount and you can true up the mount and remove most of the excess vibration. 4. sloppy motor mounts from factory, they were off by 3/8 inch. This was a majoe source of vibration. I remarked and redrilled mount brackets. Just measure the distance from edge to hole where the fan is mounted prior and not a big deal. 5. I used thick neoprene washers as isolators. this was worth while. All said and done, i have a good ventalation system. Home depot could put pressure on manucaturers to build better quality. Our sharing helps all to know before you buy and I did read about every issue I had, minus the defective thermostat. It is still better than anything else at his price I could find. July 31, 2012
Rated 4 out of 5 by Attic fan change-out The fan arrived quicked than estimated and appeared to have no external damage but when it was removed from the box, it was slightly out of round. It only took a couple of soft "squeezes" to return it to round and the blades would then turn freely. After reading other reviews, I opted to replace the stock bolts, which had very little clearace between the bolt heads and the fan blades, with flat head bolts. Cost was about two dollars and well worth the change. With a neighbors help the installation took about two hours including removal of the old fan and installation of an on-off switch for future use if necessary. Don't believe every change-out is going to be an exact fit. We had to construct a new housing around the existing shutters using 1x3s to have enough clearance. Each job will be somewhat a custom fit. The fan is quiet and works great. August 27, 2014
Rated 1 out of 5 by Don't Buy I bought this because of the high ratings given here. When I pulled it from the box brand new, I could not spin the blades by hand without them hitting the sides of the cage. I had to buy pan head bolts so the blades would not hit the bolts provided with the install kit. Installing it in the attic, I had to bend the blades and the cage to allow the fan to spin without hitting anything. Its been running for one week now and has been noisy with vibration, but running okay. Now this morning it sounds like the blades are hitting things again, making a popping noise every second or so. What a hassle. Its going back to Home Depot next chance I get and will replace with a new [unnamed competitive brand] unit like the one that was running noisy but okay for the past 10 years before it finally failed. I should have never ordered this, I should have returned it as soon as I saw how poor the quality was upon opening the package. The UPS postage sticker to return it was included in the shipping package (now there's a clue). Oh well... don't you make the same mistake. I just wish there were a high quality fan available for this application, not just these cheap ones. I would pay double or more for a unit that is quiet and lasts a long time without annual tweaking.

Rated 4 out of 5 by 1650 cfm "energy efficient" ventilator This is the exact same fan as the one they make selling for $30 less. I bought three 1650 CFM ventilators then ordered three more of the "energy efficient" models costing $30 more each. When they all arrived they were all the same. No difference in any component on them. It cost me $100 extra to get the creative marketing version called "energy efficient". October 14, 2014
Rated 5 out of 5 by Strong motor This fan was used to replace a fan that had went out. This fan must be stronger than the fan it replaced. It works great! July 29, 2014
