Product Overview

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.

Fan Will not start

Motor just makes noise when the switch is turned on. If I can spin the fan fast enough it will start and continue to run. It is great when it runs but I am the only one who can start it. Not good for my wife.

Answer: 
On many fan motors, the start capacitor can be replaced ($25 part) without replacing the motor. It's attached to the motor.

I see no reason why you couldnt put this in a wall, but that is not what it is meant for. The fan is not meant to be exposed to any elements or moisture, but hey, a fan is a fan so why not stick it in a wall?
The blades might not be balanced for horizontal use. This was designed to be installed vertically, so you can cram this in a wall, or you can buy a fan meant for wall use and know you will be Read More

Answer: 
I have done this two ways. One year I built a box over the fan out of 2 inch insulation, it was a real pain to take off and put on. The last few years I have disconnected the belt and put insulation against the attic side of the shutter. Then on the ceiling side of the shutter I use a window insulation kit to stop drafts. Works great!

Customer Reviews

Rated 3.2 out of 5 by 55 reviewers.
Rated 5.0 out of 5.0 by Good value, performs as expected Excellent fan that is quiet, operates as expected. Installing as a replacement fan can be tricky but not difficult. June 30, 2016
Rated 3.0 out of 5.0 by Good fan, some bad stuff The fan is powerful, not very noisy, and certainly gets the job done. My complaints are, it arrived damaged (the louvers needed to be bent back into shape to fit flush) and the instructions provide no actual measurements. We did a joist cut install and it took about 6 hours from start to finish for all the measuring, cutting, framing, and attic crawling around. Recommended modifications include, put padding/weatherstripping on the frame to reduce vibration, drill two more hole in the louvers to have more screws holding it flush, and caulk everything in for a perfect seal. This is a good value, but its always frustrating to pay $318 for something and have it show up with enough damage that you have to go fabricate it back to working order. June 13, 2016
Rated 1.0 out of 5.0 by poor quality control and manufacturing purchase 30 in fan - first problem - did not have hardware kit in packaging - Second - the pre drilled hole were not align correctly - were 3 inches off center - could not be mounted on beam - third the directions for tightening the belt were very terrible it is sad that this is an American made product June 4, 2016
Rated 3.0 out of 5.0 by Bad experience at Home Depot. The fan works great, but setup was very hard considering box had been opened, NO installation instructions, missing parts (fan switch). But after installation was complete, was all that I expected. Problem was with retailer, not product. May 17, 2016
Rated 1.0 out of 5.0 by WORST PRODUCT I BOUGHT THIS YEAR The dimensions of this product do not match any American standard. Installation is very difficult and will require extensive fabrication. The box i received had been previously opened and must have been a returned item. Quality of louvers is flimsy June 5, 2016
Rated 5.0 out of 5.0 by As Advertised HD didn't have it out on the shelf, so I had to ask them to get it down with the forklift. The box was unopened, and everything was in the box. Easy to install per the instructions. I did a joist out installation in my hallway. Turned out that the spot I needed to put it had a dummy joist anyway, so I just knocked that out. Any weekend warrior should be able to install with no problem. Be sure to cut the opening for the louvers, since they are smaller than the fan. get some extra 1x4 lumber to allow centering the fan in the opening. Fan is quiet when running. Standing under it, it's slightly louder than standing next to a running dishwasher. Installed it in the hallway away from the common areas and between the bedrooms. Barely hear it in the common areas, and some low, white noise in the bed rooms. Runs well, and keeps our 1500 SF home comfortable. We turn on the AC when the weather gets above about 85F outside. Even when it's warm, the house is comfortable because the air is moving. Should pay for itself this summer in utility bills alone. May 30, 2016
Rated 5.0 out of 5.0 by Great working producr I installed this product 28 years ago. With the exception of losing low speed, my fault, it has worked great. Replaced the belt once. Was a challenge to insulate. Built a raised wood frame and hinged fan on top to allow room for insulation in winter. Installed cut off switch to remove power from motor while raised. May 1, 2016
Rated 1.0 out of 5.0 by Motor Died BEWARE! Motor died after only 7 years of minimal use. We probably only used it a few days in the spring and a few days in the fall of each year since it was installed. My local Grainger store said the motor is very unique and difficult to replace with anything generic. Almost like they designed it to be so specific that you must buy another from them or replace the whole fan with a new one. I won't give them the satisfaction so I will make something generic work and never give this fan company another dime. March 21, 2016
