Is vibration / noise normal?

Mounted it in my shop less than a week ago. It works fine but the motor/fan assembly is vibrating the shroud to a great extent and it is VERY noisy. I fear that the vibration will end up loosening the bolts that attach the motor/bracket to the shroud or that the metal will fatigue and crack. Is this normal?
Asked by: GP
Vibration and excessive noise is not normal. If there is not enough air intake ventilation (min. of 700 sq inches of NFA intake) this can cause blade cavitation (vibration and noise). Please call Technical Services at 800-211-9612 for additional information, M-F 8A-5P ET.

1540 CFM Power Gable Mount Vent in Mill is rated 4.2 out of 5 by 117.
Rated 5 out of 5 by from Low amp draw and good air flow for the money. I purchased the Master Flow 1540 CFM Power Gable Mount Vent to today with the idea that I would need to return it based on a few reviews claiming the fan is loud and poorly built. They must have a defective fan or installed it wrong. The fan works fine. I could not find any amp ratings, VA ratings or dB ratings on the fan. So I tested the fan before installing it. At no load (0.SP) it used 186watts @ 124Volts and pulled 1.7 Amps. I could not measure the dB but it is in the range of 75dB to 80dB. I have a high velocity 3-speed indoor fan that is louder. I purchased the fan to use in my 12ft by 10ft greenhouse that required 1440 CFM air change. Running the fan 10hrs per day at 186 watts it will cost about $0.21 cent per day or $6.24 per month to operate. Starting amps was just over 2.5amps. I could later convert this fan to DC with a 200watt dc/ac convertor and a 12v/25amp/hour battery and charge the battery with a solar cell. Specifications on other fans with about the same air flow used 2.5 to 3.4 amps. This fan has the lowest amp draw for about the same air flow. I could have purchase a variable speed fan and lower the amp draw to 1.1 amp but the fan with controller was $268.00. Not enough pay back to spend the extra money. I would recommend mounting the fan face down on a per-cut frame or piece of plywood so that you do not get the housing out of round, then lift the fan into place. This will help eliminate the any vibration after installed.

Rated 5 out of 5 by from Easy Installation, works fine so far I installed it yesterday. It was really simple. I held my trouble light against the thermostat to test it and it worked perfectly. Previous comments complained about the screws hitting the fan...not a problem, I just put notches in each of the fan blades so they could spin freely. ...Just kidding. I guess MasterFlow fixed the issue. My screws were low profile so there was plenty of space. I am happy with the fan and recommend it, especially at $84 (the price in June 2013).

Rated 4 out of 5 by from Started Saving Money AfterThree Months In Sacramento, CA this attic fan costs about $8.00 per month to run 7hrs/day in July 2010 through SMUD. That's $0.26/day. If it trims your $200 HVAC bill by 15% you save $22/mo. in July, ~$20 in June and August. Fan costs $80/$22=3.6 months (#hot months to break even*). After the first hot summer you will pocket at least $60 per summer thereafter. Not including wear and tear on HVAC and added air filters, noise from HVAC. * break even cost assumes proper DIY installation.

Rated 4 out of 5 by from Good so far, requires 16" opening I installed this fan in our attic about 2 weeks ago and it's been running a lot since then due to high temperatures here. So far it's very good. It's mounted to the studs about 3 feet above our bedroom ceiling and the noise level is good. It's quiet, but I can hear it running if I listen carefully, which I like. The only advice I can give is that the brackets that come with the fan require 16" between the studs. I had to swap those brackets with the ones from the old fan to reach the approximately 18" between my studs in the mounting location.

Rated 4 out of 5 by from Cools attic down For my diy instal it took about four hours from start to finnish. The gable for my home was hard to get at. My home actually has one gable in the master bedroom. So only one PG2 attic fan was needed. It readily pulled the heat out of my homes attic space. Set the thermostat too cut off at 105 degrees. On a 80 degree day. The fan had my attic cooled down in about 1.5 hours. This PG2 has sealed bearings on the motor. Maintence free. I almost wish I could oil it. The reveiws have me worried about the fans life span. I also purchased the automatic shutter cover. The cover opens when the fan is running. It's worth the extra money. I live in Georgia. My roof has black shingles. I have had this home for three years. The heat up stairs was so intense. I bought a 12,000 BTU window AC unit to draw the heat out. My central air worked fine downstairs. It would not do any good for the upstairs bedrooms. My hope is the 1540 CFM gable fan will do the trick to off set my cooling cost's. After instalation there was a huge difference in the heat upstairs. It's more then certain that this attic fan will be getting a huge amount of use. List of materials: 1 Master flow 1540 CFM fan 1 2X4 too make frame 1 tube of clear silicone caulk 1 package of 10' piece of 14 gage wire 3 wire nuts 1 Master Gable End Shutter 1 package of 3.5 inch screws Total cost for the job was $154.00 which roughly translates to one months cost to cool my three bedroom home. This fan should pay for itself in about three months. The comfort it will bring during the summer months is PRICELESS...

Rated 5 out of 5 by from These should be in every house!!! This item is awesome. It was very easy to install with just the basic knowledge of household wiring and everyday hand/power tools. Set the built-in thermostat (once it's installed) and forget it. It sucks the hot air from your attic and blows it on the neighors! LOL! It's very quiet, even when you are outside looking up at it. People swear by whole-house fans. But you have to wait for it to cool down outside in order to draw the cool air into your house. Great, but what if it never cools down? I say don't let the hot air build up in the first place. It pays for itself becuase I don't have to turn the A/C on until it gets to 100F+ here. Note, my install was made easier due to the power outlet being very close by to the vent I mounted the fan behind. A no-brainer idea/item.

Rated 4 out of 5 by from Good Value and much quieter I have had two of these installed in my attic for the past 15 years. They are usually on all day every spring and summer and worked great. At almost exactly 15 years, one of them just wore out and failed. I went down to HD and got this latest version and replaced the worn out unit. The old unit wasn't too terribly noisy but the new version is super-quiet. That was a very nice surprise. A few months later, the other one failed so I guess the lifespan you can expect is right on 15 years. I think that is pretty good considering how much mine worked during 2/3 of the year, every year. So, I went down and got another to replace it. These new ones are so quiet, I really can't hear anything from the bedroom right underneath them when they are on. I had to stick my head up in the attic to make sure they were actually working. They are very easy to install and move a lot of hot air out of the attic. It makes a huge difference in the house temperature in the summer.

Rated 3 out of 5 by from mixed results Annual oiling is required. There are little oil port dimples on both sides of the motor. It is a little tricky to get oil into the port on the blind side of the fan. The motor must be installed so the ports are up. I have two fans (two attics), one has never given a problem over a decade, the other has had the motor replaced twice in 5 years. The replacement motor seized but that is probably because it was venting plaster dust for a week of bathroom remodeling. (Take out the bathroom fan and the attic fan vents real well. The fan blades had 1/16" of dust on them.)
