Product Overview

Whole House Fans are ideal for residential use in mild to moderate climates as a supplement to air conditioning. Our fans use a precision-balanced blade assembly and a re-engineered bracing system for quiet, efficient air movement with low vibration, alongside an automatic shutter in a powder-coated white finish to blend in seamlessly with your ceiling. Install as a joist-in or joist-out configuration. Whole House Fans offer an efficient way to reduce cooling costs by pulling fresh air in from the outside, expelling the warm air up into the attic, and pushing it out through the attic exhaust vents.

These fans need at least 8-10 square feet of net free air to draw from. This could be obtained from open windows, doors, or permanent vents. Additionally, the rough opening for the shutter is 26 by 28 inches.

what is the total watts

Asked by kim July 11, 2019
3
Answers

Mfg states 3.8 amps and 120 volts. Watts equals amp time voltage 3.8 amps x 120 volts= 456 watts. If you restrict the air flow the amperage will increase which will also increase the wattage. It’s important to make sure that you do not restrict the intake and exhaust so the fan can properly discharge the volume of air this fan can move in either speed low or high speed

what is the measurement for shutter

Asked by frederick May 7, 2019
2
Answers

Flip it over and use a cardboard box then use a pencil make the measure of the insert portion. Double check it is the right size. Find location you want to install it at then nail it to ceiling. Copy cutout then remove cutout and make your hole but before you start make sure you will have room for your fan in the attic and nothing in the way

Can the shutter veins run the opposite way with a joist out installation?

Asked by Henry April 28, 2019
2
Answers

I don't know what you mean by a "joist out installation". The shutters open upward, toward the fan. When I installed my ceiling joists, I fabricated a box for the fan housing to set on. However, the shutters open from opposite sides to the center and the center piece is about 3" wide. This might possibly allow for installation over existing joists without cutting. I suggest asking the store if you can open the box and look at the installation instructions.

I researched and chose this fan with the direct drive as apposed to the belt drive only because of the fact that a belt drive has 2 bearings instead of the 1 bearing on the direct drive. One less bearing to go out and I also read that the direct drive (may) be a little quieter. The fan came as advertised with no issues concerning quality or packaging. To me, the motor supports and frame construction seemed adequate, so I chose not to alter any of those [it does come with a 10 year limited warranty]. I did not care for the double switch configuration so I ordered and installed a single Hi/Low/Off switch that worked perfectly for my situation. I did make changes to the recommended install protocol, but only because of the existing conditions in my attic. 1) Where I chose to mount the fan, was in a centrally located position in my hallway, but because my hallway has a drop ceiling at 7'-0", I was concerned with the surrounding 8'- 0" ceilings directly adjacent to it and the accompanying blown-in insulation falling into the fan. Additionally, having a roof structure with 4/12 pitch, maintaining the recommended 36" clearance to the roof structure became problematic. So I built an extended flue out of 3/4" plywood to clear the fan above the surrounding insulation and also angled the flue at 45 degrees to increase the fan to roof clearance to well over 8 feet. This flue system also increased the fan blade to ceiling shutter opening to a developed length of just over 55 inches. I also installed a continuous 1/2" thick rubber gasket at the fan box to flue connection so as to reduce any vibration from the fan being transferred to plywood flue. This combination of gasket, angled and extended flue, has made this fan quieter, I believe, than if I would have installed it immediately above the ceiling joists. This extended angled flue with the improved clearance to the main roof structure promotes copious quantities of attic air movement to where the attic is actually as cool as the indoor air. Since I live in the California Central Valley, where summer daytime temps average 95 -108 degrees, this has been well worth the price and the effort. I leave the fan on the low speed thru out the night with a few windows open and with a well functioning ceiling fan over our bed, my wife actually gets a little chilly. I do not own a decibel meter, but I can have a conversation in normal speech volume directly underneath this unit while running. You do hear the unit running, like others have stated, but the sound is less than that of a 20 inch box fan. I had to preliminarily build and assemble this unit in my shop and then disassemble and reassemble in the attic because of the limited size of the attic access openings I was dealing with. [see pics] In the final analysis, I wish I would have done this years ago and I would highly recommend this unit to anyone.

Last summer, the weather was in the 100's, my house cooled down quite quickly after 6PM. Instead of getting AC installed, I decided to install this 4600 CFM 24" from Home Depot. The shipping was quite fast. The box came a little torn, but everything inside was intact. One of the blade was bent due to shipping, but with a little long nose pliers, I could straighten it out. The box actually came with everything needed to install, 2 switches - one for ON/OFF and one for HIGH/LOW speed which has instruction on how to install. I used the Joist-in installation, no cutting, just adding frames - The FAN is actually a little smaller than the cutout for the Shutters, so we need to make a frame over the joist to fit the FAN on top of the Joist frame (custom). The FAN works right out of the box, the switches work, the fan is a little loud because it's a direct drive instead of belt drive, I didn't want to bother with the installation so I bought this one. We only need to turn on 1-2 hours, so the sound to us is bearable. When the FAN is on, I went to the master bedroom with the windows and doors opened, I could feel the breeze coming through the windows - the fan is really powerful. I went down stairs and I feel the breezes on the windows too. It's amazing. I bought a WOODS timer 1-2-4-8 hr from Home Depot to replace the ON/OFF switch and it work wonderful. Now we can just set the time and forget about it. When we grilled meat in the house, the exhaust fan couldn't remove all the smokes, but this one really help to suck out all the smokes, wonderful. Do I recommend this one, yes, you do need to customize the frame over the Joist, find a good location on the hall way for all rooms. Make sure the FAN area is clear so the Air can go through easily. You'll need a few 2x4" 8' and some 2 1/2 in screws. If you want some tips and hear how loud it is, email me or search youtube 3dogs1monkey channel since I can't post videos here.

I was shopping around for a good WHF and went through different reviews, I got this fan from Home Depot on line and got it installed couple of weeks back. I am happy with it. Pl read the reviews through different sources to reduce noise. I have added foam to reduce noise and a timer for ease of operation. Before purchase, please check whether your attic vent has adequate ventilation (calculators are available in the internet) to prevent returning the product which is not only inconvenience to the seller and manufacturer but also loss to them. Any inconvenience and loss incurred to them is also to us as price will be jacked up to compensate the loss. I very strongly believe that good amount of research is a must before any purchase..Less ventilation at attic would overload the fan motor. This WHF comes with wooden box, two speed switch and a on/off switch. I engaged an installer and paid $220.

When the fan arrived, the motor and blades were loose in the box. The motor is supposed to be fastened to the metal brackets with four screws. Three of them were completely off and one was hanging by a thread. Fortunately, the blades and motor did not get damaged in transit. The way the brackets were attached to the wooden box with screws is a poor design and would most likely loosen with the vibration. I took the screws out and replaced them with nuts, bolts, washers, and lock washers. The instructions are confusing, but I was able to figure it out. It took quite a bit of work to build the framework to seal off the air from the attic. I bought a fan years ago which had a better design. That one had a cowling that fit over the fan and sealed off the air from the attic so you did not have near as much work. . Also, they tell you to seal all the cracks with caulk, but neglect to tell you there will have to be a hole for the wire to go through. This was installed in the garage. Once installed, the fan is working well.

I'm glad I bought this fan, it was easy to install by following the instructions. It's not noisy at all, in fact it sounds just like a standard floor type fan. It definitely moves the air thru the house very well. Originally when I opened the box, it was missing the wall switches and Wall Plate that was supposed to be included, but just a quick call to Home Depot customer service corrected that. They immediately contacted the manufacturer which in turn Fedex'd me the missing parts. Overall my experience was great and I have already recommended this fan to my co-workers and My brother. We'll worth the $199.99 I paid. Not only cools down the house, but it also cools down the Attic quickly.

Very happy I chose to install this Whole House Fan!!!

I wasn't sure if I was going to be able to install this whole house fan, but I was rather pleased to find out that is wasn't that difficult and was SO worth my effort to install it. I now use this fan almost every day to bring in cool air in the late afternoon or to just feel the breeze through my home...this was a "breeze" for me to install. I expect MUCH cheaper electricity bills now. I have yet to use my AC and much prefer to nice air flow through my home. I was very hesitant on trying to install this, for my expertise is not there, but surely I found that it went very smoothly, right down to installing the 2 switches (ON/OFF and High/Low) turned out to be not a big deal. The only drawback I could possible say about this fan is that it is a bit noisy...well, it is a large fan moving a lot of air, I expected it. But again, I cannot be more happy with the outcome. Even when my wife decides that dinner needed a little extra cooking, either the smell of fish sauce or the smoke of a neglected dinner on the stove, this fan is perfect and does exactly what I expected. From the montly savings in electicity for AC and the awsome effect of having fresh air running through my home, I 100% would recommend this fan for any home. The extras I needed to purchase to complete the installation was: 1. 2 lenghts of 2x3x6' for the base of the fan 2. An electric 2 bay box to install the switch (I actually used a 3 bay and replaced a single switch box that ran my laundry room fan into the 3 bay box that looks great) 3. 25ft of romex to install the power and switch 4. A power tester for the wire (I was being extra careful) Even cutting the whole in the ceiling proved effortless as the instructions were very easy to understand. Very pleased customer.

Well made, draws air very well, but MY GAWD, what noise!! This fan unit is so loud that you can't leave it on and sleep or even hold a normal conversation - even on 'low' speed. 'High' speed is a roar. Installed the fan in new construction. Fan specs were confirmed appropriate for the house attic venting capacity. Installation was straightforward. Instructions state if noise is an issue, install blocks to raise the fan unit further into the attic space, so I did. No noticeable change. Contacted the manufacturer (Ventmatic) and sent them a video. They indicate the noise is 'normal' and nothing further can be done. I have had these fans in previous houses and none of them were this loud. NOTE: The fan blades are installed upside down for shipping. Make sure to loosen the set screw and remove the blade before installing. Otherwise it is amazingly awkward and difficult to reach under the blades!
