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 allows 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 (model WHT36, sold separately) enables you to run your fan for a pre-set amount of time as needed. 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.

Can this fan be installed vertically (wall) or does it have to go in the ceiling?

Asked by: FSM
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 ok,

Looks to be well built, but we were a little unhappy by the low-frequency noise it produced (I would call it "choppy", which eventually convinced us to return it. Not so loud that you couldn't carry a conversation, to be sure, but annoying as a background sound while reading or using a computer, at least to me. This was with zero constraints airflow on the intake or output sides of the fan, they warn you it could be louder once it's installed and there's a limit on airflow. Power use was 380 watts at 6000cfm; at the lower speed it was 290 watts.

Rated 3 out of 5 by from 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.

Rated 3 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 4 out of 5 by from 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!

Rated 1 out of 5 by from 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

Rated 3 out of 5 by from 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.

Rated 1 out of 5 by from 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
