The Master Flow 6000 CFM 30 in. Belt-Drive Deluxe Whole House Fan is a smart energy saver for any home in a climate where air conditioning costs are a concern. It will allow you to beat the heat by forcing hot air out of your home through the attic space while bringing in cooler outside air through your windows and doors.

Adding a Master Flow 12-hour timer (WHT36 – SOLD SEPARATLY) will allow you to run your fan for a pre-set amount of time as you need it. A minimum 1100 sq. ft. of attic space with a minimum of 1152 sq. in. of net free area attic exhaust is required for proper operation.

Rated 3.1 out of 5 by 35 reviewers.
Rated 2.0 out of 5.0 by Be Careful. Pulleys might not line up Bought one made in 2011. Found motor pulley would not line up with fan pulley. Went back to store and opened another box. Same issue. I found a free repair description at invisco. March 22, 2012
Rated 4.0 out of 5.0 by works great.. I did an install from scratch. We recently moved into a 3,200 sf house, and those little window fans simply do not do the trick anymore.. that and we now live in a two story house.. heat does rise I found out. and the upstairs was much hotter than downstairs.. but enough of that.. here is the meat and potatoes.. I first had a hard time finding a good spot to put the fan. It needs to be in a central location upstairs. We have a low sloped roof, and blown in insulation. It was summer when installed. It really was tuff working in a high heat condition trying to find a spot that worked.. I finally did. I cut a joist, and reframed to fit the box fan. No problem. I ran new wires down the wall to a new outlet location near the fan. I did get smart, and installed a timer prior to the two speed switch. I could so see my teens leaving this fan on all night.. and that is not what these are for. I usually leave the switch on high.. and simply push the 10 or 20 minute button on the timer and walaah! The fan actually works great. DO make sure you open enough windows so as to not make the fan work too hard.. you will reduce the life of the fan of course if it is overworked. This thing moves air... a lot of air! whoo hoo! it will actually slam doors to room with open windows, so make sure they are fully open. The fan is actually much queiter than we thought and quieter than the display fan at the store.. not bad :) We love the fan and would definately recommend! August 31, 2010
Rated 3.0 out of 5.0 by This unit was a replacement because the origional fan in the house had a burned up motor (actually cheaper to replace the fan than buy a replacement motor). Installation instructions were sketchy at best...even with an existing installation. It took about 5 hours to retrofit this unit to existing installation. It has been installed for 3 days and has good airflow, but I was a bit dissapointed because the shutter has a vibration to it. The fan frame looks flimsy compared to the unit it replaced, but you get what you pay for. I would say for the money, it was to be expected. July 21, 2010
Rated 5.0 out of 5.0 by Review of the Master Flow WHOLE HOUSE FAN 30 In. I live in the Lake Elsinore area of Southern California in a 4000 sq ft two story house. The typical climate here is warm to HOT during the day (80 to 100+ degrees) with cooler nights (50 to 70 degrees). Our attic would become heat soaked during the day and retain a temp of about 150 degrees or hotter which would require the use of the AC in the evenings even though the outside air was cool. After some research on the web I decided a Whole House Fan should be the ticket to help minimize the use of the AC. I looked at units that cost as much as $1000 down to units as low as $200. My biggest concern was to utilize a fan with enough CFM to move air in and out of our house in 10 to 20 minutes. Basic calculations suggested that a 11,000 CFM unit would be required. This seemed a bit high to me, not only that I doubt my attic has enough ventilation to flow that much air. I decided the Flow Master 30 inch model 30BWHFS which flows 6000 CFM should be more than adequate. I purchased the unit at my local Home Depot. I had to open the unit in the store because no where on the box or on-line are you given the actual dimensions of the fan frame or louver assembly and I had limited space for the install. The wooden box frame thats attached to the fan has an outside to outside measurement of 34 inches. The opening for the louver assembly will need to be 34 X 28 inches. Its kinda odd that the fan frame OUTSIDE measurement is the same as the opening for the louver. This really isn't a big deal but if the louver opening was a little shorter you could build perfect box around your rafters that would fit both the louver and the fan but this is not the case. Because of the way its made you have to build the rafter frame a little longer than the fan frame and seal the gap with the supplied sealing material. I used 1 x 4s but see no reason the supplied sealing material wouldn't work. The install was pretty straight forward and simple for anyone with basic hand tool skills. If I had to rate the install on a scale from 1 to 10 (10 being hire a pro) I would rate it a 3 or 4. The fan comes with a two speed wall switch and the fan is wired as a two speed unit. A common white and ground then a black for high speed and a red for low speed. Since the size of my house is on the larger end for this fan I wired it to a standard light switch and utilized the high speed circuit only. The louver assembly is very simple. Its nothing more than a gravity type. The fan draws the louvers open and the louver free falls shut when the fan is off. The fan has more than enough power to cool down my house in 15 minutes or so. With several downstairs windows open about 4 inches the flow through the openings is pretty substantial. Like many things noise is subjective. When sitting downstairs this fan is no louder (in fact it might be quieter) than a standard box fan you would place on the floor. Its a touch louder when you are upstairs but not bad at all. I think the belt drive has a lot to do with why this fan is as quiet as it is. All in all I give this fan two thumbs up and would buy another in a heart beat. This of course assuming the longevity of the fan is up to par. Notes: This fan does not utilize the pull chain switch that is on the smaller 24 inch. You must wire it to a light switch. I happen to have one recessed light in the area where I wanted to install the fan. I removed the light and utilized its wiring to power the fan. You need to check the tightness of the bearing set screws and you have to mount the motor and adjust the fan belt tension. When adjusting the belt tension make sure you do not get it to tight. It can be pretty lose and still preform perfectly (its not like the fan belts in your car). You also have to align the pulleys. This sounds like a lot of work but its not and pretty simple.

Rated 4.0 out of 5.0 by Very satisified with fan. I installed this fan in May of 2010, and am reviewing it in June of 2013, so its had two solid summer seasons of use before my review. I liked that the joist did not have to be cut, but ended up cutting anyway at the suggestion of Techincal Support to help reduce noise and maximize air flow. When installing the fan, it was set on foam water pipe insulation and held in place with 4 L brackets. This greatly reduces the transmitted vibration noise. The fan I bought had the misaligned pulley problem, but a quick call to Tech Support said some pulleys were mounted upside down, and to remove, flip, and reinstall it. OK, problem solved. When doing the electrical work, a double gang box was installed so a timer could be installed later. The supplied Off/Low/Hi rocker switch failed in about a week, and Flow master sent out another right away. My home is a typical center hall colonial, about 2500 sq ft and ridge vents and soffit vents built in the '90s. The fan will pull plenty of air through both the first and second floors. But it will take a little practice until you find the right amount of window opening on the second floor to keep a good breeze on the first floor. I found that one window in each of the 4 bedrooms open about 6 -10" will cool the upstairs and still pull a strong breeze through the slider doors open down stairs. Yes, it does make curtains flutter in the breeze and most of the time it is set to "low". I find the fan is loud upstairs even on Low, but barely detectable downstairs other than the breeze blowing papers off tables, etc. But no louder than fans I have had in other homes. It has been working just fine, and really does help reduce the A/C electric bill. A nice accessory is a timer switch. I found the Intermatic FD6HW 6-Hour Spring Loaded Wall Timer to be good choice. Also the timer switch does the On/Off function so the supplied fan rocker can be tossed in favor of a standard 3-way wall switch. Run line to timer, then timer to 3-way (black screw), then red and blue fan wires to 3-way (brass screws). Now the 3-way does the hi/low function and the timer switch does on/off. All in all I am very satisfied with the fan. I was not too impressed when I opened the box in the store because it was made of thinner sheet metal than fans I had years ago. But it has performed as it should and I expect many more years of dependable service. Follow directions, make sure there is enough attic vent, do not over tighten the belt, and you should have no problems. June 7, 2013
