20" Wall Mounted Shutter Exhaust Fan, Automatic Shutter, with Thermostat and Variable Speed controller, 2.2A, 3368 CFM, 5000 SQF Coverage Area Silver (ILG8SF20V-ST)

VERDICT: I highly recommend the iLIVING 20" Wall Mounted Shutter Exhaust Fan is an excellent value, and a highly effective exhaust fan. Volume of air movement is impressive. It operates at reasonable a sound pressure level of ~65 dB (highest operating speed) as measured with a sound meter SPL app 1 meter distance. It implements aluminum gravity shutters that automatically open with operating airflow, and reliably close when turned off, keeping critters from entering. There is a safety grating completely covering the fan, ensuring that fingers cannot ever come in contact with blades. I recommend mounting the fan high up anyway. Context: We installed this in out 2-story storage warehouse to cool the space during Summer months. We are in Hawaii where temperatures can reach a high of 89 degrees F outdoors. Design situation: Cross-ventilation with a single exhaust fan, pulling air across the ground floor of the warehouse, up a stairwell, then across the entire 2nd floor. Site details: We have CMU concrete walls to side and back, and a corrugated metal roof with a drywall ceiling (uninsulated), and the South-facing front wall is cement fiber siding with insulated walls. Upstairs warehouse storage area being ventilated is approximately 12,500 cubic feet in volume. Assembly: The unit comes completely assembled with the fan ready to be installed to a box frame in a wall. Install, then plug it in. Mounting location: Somewhat high on the 2nd floor at one end, cross-ventilating position. Installation: Mounted to the wall framing, then framed in, with insulation in the walls all around above, to the sides, and below the unit. This eliminates any rattling vibration from the unit. Otherwise, expect the fan box and shutters to rattle. Essentially, this fan was mounted with zero static pressure (no restrictions on airflow except from the shutters and the safety grating). Cooling: It can move a peak of >3,000 cubic feet per minute (cfm), which is way more than I need for the area that I'm cooling. Can reduce indoor temperatures from 94 degrees F to 83 degrees F in about 45 minutes. We could cool the upstairs area in less time by opening upstairs windows; however, we choose to instead use the fan to cool the downstairs area as well. I recommend running the fan early in the morning to bring in the cool dawn air, then operate it again from the mid-day when heat starts to build. Operation: There is a temperature control dial so you can vary at what temperature that the fan will come on. It is hard to get precision to a degree, but it is helpful. There is also a variable resistor fan speed control if you don't need maximum air movement all of the time. Noise level: We measured a peak of 65.2 dB noise level, low enough to have a normal conversation 10 feet (3 meters) away at normal voice levels. Electrical: Very efficient. At a peak draw of just 253 watts, even at our most current expensive Hawaiian Electric rate of 42.44 cents per kWh, we're paying just under 11 cents per hour to operate the fan. I do not recommend running an extension cord to the unit. I recommend that you have an electrician provide a receptable within operating reach of the fan unit. Shutters: The shutters operate reliably every single time throughout our initial 6 months of usage. These are gravity shutters with weights built into the bottom edges of the louvers. These shutters are sufficiently watertight, and with two recent storms blowing wind and rain directly at the shutters we have very little water intrusion. The water intrusion was due to the gravity closed position being overwhelmed by >50 mph wind gusts, which had enough updraft to partially open the louvers for instances, thus allowing wind-blown rain to intrude. This is probably a shortcoming of gravity (weighted) louver closure versus spring loaded designs. Insects can enter through gaps in the shutters. If you're really that concerned then you can probably enshroud the grating with #16 insect screen, though you may be disappointed with how much airflow restriction that you would introduce. So there are consequences, as such. Size: For the volume of the space (<12,500 cu. ft.) being cooled, the 20" fan size is well oversized. Since we are cooling the lower floor of the warehouse as well by drawing air through the 1st floor and up the stairwell to cool the 2nd floor, this size of fan (20 inches diameter) was perfectly suitable for our situation. You need to right-size the fan size to the space which you are cooling. iLiving offers a full complement of replacement parts including shutters, fan assembly, fan motor, cord, and thermal control switch unit. This unit comes with a grounded plug that can either be direct plugged into an outlet, or plugged in to their temperature and speed control switch that would be plugged in to a receptacle. If you plan on using the fan at high speed all the time, you would need to have the outlet to which the fan is plugged into as switch-controlled. That requires a professional electrical installation. Expectations: Fans are electrically very simple, and I expect this fan to operate for years to come. I can see this being a perfect fan to be gable mounted in an attic to exhaust hot attic air and draw in cooler air through the soffit vents. Yet these fans operate quietly enough that these fans are great for ventilating a barn, workshop, shed, even your garage. I've provide photos of the external mounting, internal finished view, the operating control unit, the SPL sound meter reading, and a short video clip to hear the fan. Highly recommended.

As stated in someone else’s reply, could use a touch more weight to close when off. I haven’t got the laser out to add a couple earth magnets yet.. but should work fine. This 20” fan moves some major air!!! Will pull the door closed on me! (Garage is 30x20x10) I have an uninsulated metal garage. (It will be in the near future) It gets hot in there to say the least and this fan knocks off 50-80 degrees!! (Guess) I can actually walk in the garage now when the suns out! Once a split unit is installed I’m hoping this won’t be needed much. Longevity has yet to be seen .. been installed for a couple weeks now with the thermostat hooked up and set to 88 (there about) it works..

Works good so far. Its nice for the price and moves air very well. The shutters make a little noise when the fan is moving fast. At low setting it's pretty quiet.

Easy to install, fully assembled. Surprisingly easy to maneuver in the crowded attic space. Noticeable difference in attic temperature right away. Runs quiet. I'm very happy with the thermostat having a fan speed setting. Fulfilled exactly what I needed to cool the attic.

This is the second fan we have bought from this company. Noice level is mediocre, not too loud. I was able to easily plug it in, set the temperature and leave it. Since the first one worked so well im onto buying my second for a business expansion. Looking forward to seeing how it does.

Just installed 2 of these side by side in my 20x20 metal workshop and I am so happy! These things run pretty silently, draw a TON of air, and seal the space when not in use. Would recommend!

Build quality is on par. Worked as expected. Small thing to mention, I planned to place the controller in the garage and run an extension cord between then controller and fan so I could control the fan from garage instead of it just being temp controlled For whatever reason it will not work with an extension cord between controller and fan. However you can use an extension cord between the wall and controller.

Easy to install. Not very noisy. Easy to set up

Works great, lots of air flow.

I bought 3 of these as ventilation for vehicles on my dynamometer. Works awesome! Great product. 5 stars.

Easy install into a kitchen to blow the heat out

Great fan. Been using for 6 months now with no problems
