        How many wattage need for starter
        ByJul 4, 2026
        1 Answer | 
        Answer This Question

        This unit is a 1.65-amp motor equipped with a start capacitor; we recommend ensuring at least 3 amps are available per circuit. Please note that wattage is calculated by multiplying amperage by voltage.

          what amperage and wire size is required
          ByJun 1, 2026
          1 Answer | 
          Answer This Question

          The ventilator should be connected to a 120 volt, 60 hertz, grounded circuit only with minimum 14-gauge wiring that has at least 3 amperes of available capacity. If you cannot confirm there is sufficient electrical capacity on an existing circuit, install a separate dedicated circuit. Do NOT use an extension cord to operate.

            I have 2 Bitcoin Miners exhausting via a 12 inch diamater duct to the outside of my garage. I do not have a cover for it, and just have a 12 inch hole in the side of my garage. Measured the CFM and it is 1100 exhausting. Would this work as a Cover?

                  I don’t recommend it
                  I bought it in January. The motor is not working. I went to Home Depot. They sent me to the airflow. I called customer service couple of times. Nobody return the phone product. It’s garbage I don’t recommend it.

                      Good fan with minor design flaw
                      After installation, the attic became immediately cooler. The fan is quiet and I can barely hear it after I close the attic pull-down ladder. Two days later it was raining hard. I noticed a tiny leak (one drop every 10 sec). Called the contractor back. It is not an installation issue, but a fan design issue. There is a screw on the body of the fan, facing upward. When water comes down, it'll bump the fan body and jump up slightly, seeping through the screw. The contractor caulked the screw.

                        I've purchased Many of the GAF Master Flow power vents and several years ago I purchased them because the motor had lifetime warranty but I noticed on this one it's only a five year warranty so they're easy to install and simple to put Power to but I can't say how long it's going to last or its durability because it's only been installed for one week. If you have a difficult home to ventilate and you need positive airflow I highly recommend installing a power vent. They definitely remove heat for a minimal amount of cost. As a professional roofer of 30 years when the home has ventilation issues that ridge vent can't solve powered vents do the job. Solar Vents do work but they are subject to the Sun. In Texas it can be a hundred degrees and a cloudy day that solar vent will barely move.

                        The product was easy to mount and wire. At first, it seemed that it wasn't working but when I adjusted the thermostat a bit lower, it did kick on and run as described. It moves a lot of heat and humidity out of a big attic space. In my case, the hole in the roof from a previous turnstile stack exhaust was a little bit too small but gave me a starting point to use a reciprocating saw and make a larger hole in the roof surface, this was surely the most difficult part. I used elastomeric waterproofing to seal it after installation, then further coated the area with elastomeric white roof paint. Two storms later, still dry.
