About This Product

Our Maxx Air 1,300 CFM Gable Attic Fan is built to ventilate residential attic spaces up to 1,850 sq. ft. and is a great fit for situations in which roof-mounting is impractical. Constructed using a durable galvanized steel shroud and blades to resist heat distortion, and paired with a mounting system engineered to minimize vibration and ensure quiet operation. Install is straightforward with our easy to use mounting brackets and requires no special tools to complete. Our gable vent includes a pre-wired thermostat to run the exhaust fan only when you need it, minimizing it's operational cost. This electric fan is designed to prolong the life of composition roof shingles by lowering summer attic temperatures and helps to protect attic insulation against mold and mildew in the winter by removing moisture-filled air. Install behind existing louvers or purchase our shutter model (CX2121AM), and swap your pre-wired thermostat for a thermostat/humidistat combo (XXDUOSTAT) for greater control.

        Mine is wired correctly. Why is it not coming on at all, no matter where I set the thermostat on a hot day.

        Answer This Question

        It could be the motor that is the issue. I would try bypassing the thermostat and wiring the motor directly to the power. If the fan runs, then the thermostat is the issue. If that is the case, you could reach out to us at 800 433 1626

                works as expected
                My two attic fans stopped working sometime in the last 12 years (yeah…) and these were an exact fit. Install was not that diffucult, but im confortable in tight spaces (amd hot). The thermostat works really well and I’ll check once per year going forward to see how long they last.

                  Product appears to work well after retrofitting it with screws to mount the motor directly to an existing frame. Thermostat does not shut off motor for a long time after temperature drops. Support email never answered so had to call phone number in manual. Now to see if motor runs after warranty expires. This stupid Home Depot website does not allow picture to be added even when within specification requirements.

                  Unit arrived in a timely manner. The old (existing) 'tunnel' assembly was mounted in a fashion that made the housing difficult to remove, so I installed the motor & fan unit into the existing one. The fan blade was sitting too close, so I used an Allen wrench to easily move the blade outward about 1/2". After hard-wiring the new fan, I found that the thermostat was very easy to adjust. This new unit is much quieter than the old fan, and works as advertised. It is set to come on at 90 F, and while it's running it easily keeps the attic from getting too hot- and trust me, in July in N.C.- that attic was getting scary hot (I'd guess it was at least 150 F when the old fan quit!). I can go up into the attic to retrieve items on a hot sunny day now, without fearing "heat-exhaustion"!

                  The purpose for this purchase was to replace an existing ventamatic that was failing. The supports were the same spacing and the rating was higher cfm than previous fan. The new fan seems to be more lightweight in support arms. Thus it is louder and more “jumpy.” There are four blades instead of five on previous fan. My recommendation is to go up to a larger fan so the supports may be more substantial strength. It is working, just noisy.

                    Works great, does what it is supposed to do. Straight forward install. Nice strong and efficient motor. The fan shroud could stand to be a heavier gauge.

                    This fan is quite. It has a low drone and rushing air sound. Blades are fairly well balanced, but there is room for improvement. The flex cable for the power and thermostat should be a little longer to facilitate room for ease of running power to it. As it is now it binds when trying to mount it in tight spaces. Overall this fan suits the house well and really has a positive affect on the attic temp and moisture level.

                    I have provided a photo. I installed the mounting brackets ONE of the fan blades hit the bolt heads when turned. It seems that all the blades are for some inexplicable reason different. They look like they were all hand made. To get things to work I had to change the bolt to a carriage bolt (lower profile) and actually grind down ONE of the fan blades. I made several attempts to contact the manufacture and was thwarted at each attempt. Chat, online support, phone all failed. No one available to take your call.

                    Works as advertised. Easy to install. I cut a circle out of a piece of 5/8" plywood, installed the fan on the plywood using rubber washers (vibration dampening), & installed the fan-&-plywood on the 2x4s around my attic gable vent. Put the thermostat-junction box at the edge of the plywood so the back of the thermostat box hangs free so air can surround it. I can hear the fan when it is on, but barely and only on the 2nd floor. Don't hear it at all in the 1st floor living room. I set it to come on at 110 degrees F. I can't say whether it makes a difference in temperature inside the dwelling because we haven't experienced really hot weather yet (San Diego).
