      Can this be used in a ceiling?

      Answer This Question

      Dear customer, Here is Alisa, regarding your question, it is not recommended to use on the ceiling. If you install the fan horizontally, the louvers will not open to the normal level and the air exhaust volume will be reduced. If you have any other questions, you can contact us at:Mxiclab@outlook.com

              Can the vent stay in the open position even when the fan is off? Also, will the fan work in reverse to blow air instead of out?
              ByFeb 28, 2025
              1 Answer | 
              Answer This Question

              Dear customer, Here is Alisa, regarding your question, after the fan is turned off, the louvers will droop due to gravity and remain in a closed state. The fan will not reverse and will not draw air from the outside. If you have any other questions, you can contact us at:Mxiclab@outlook.com

                  Just got the fan installed. Installing through existing metal siding is a pain, but not the fans problem. The instructions left out a measurement. My fan had 14" louvers, but required a 15" opening for the fan safety cage. Otherwise easy to instal and program.

                  I needed a fan with a thermostat for a garden greenhouse sunroom I added onto a shed. This fan is perfect for this use and has both thermostatic control for temperature control and humidity control. I found the construction to be high quality. I love the control/display unit with large format digital temperature. The manual is sufficient to get it programmed and alarms turned on or off as well as setting up the fan for max speed at both temperature and humidity thresholds.

                  It was a great fan, but I got the wrong size so I had to Return it. I got a bigger fan from the Vevor website for 50 bucks cheaper.

                  Put the fan in a custom greenhouse and is exactly what I needed….I can program the fan to come on at any temperature to any desired level.

                  Thought it would pull harder than the 1150 cfm fan I have already but they’re close to equal. Will definitely buy a larger higher cfm fan in the future but it works great overall.
