Master Flow GAF 24" Whole House Fan, 2920 max CFM, PSC Motor - WHFS24M

Great product

After two nights in use, fan blades caught the shroud and bent it. Noisy, one speed. We had to trash it. Blades bent🤬🤬❤️🫶

Great fan, but the louvers make an unholy racket while it’s running and it leaks hot air in the winter. We made an insulating block that we stuff in above the louvers during winter to seal off the attic, but that really shouldn’t be required. I think this design is good for something like a workshop, but the quietcool design is better if this is going to be in your house.

Sent us a used non working item

Whole house fans are great in the Spring and Fall as well as Summer nights. This unit is super easy to install and comes with decent instructions for someone who may think this is over their head. Fan is well made and motor runs quietly. The louvers don't look out of place on the ceiling and move freely. This will not take the place of an AC system on hot summer days but definitely does the job for my 1500 sq ft house the rest of the time.

Good solid product that arrived in good condition! Great for hot summer days to save on energy bills.

This is my second fan like this. The first one lasted 30+ years of long use, I can't complain about that!

this is a real decent fan. it works great in my shop. during real hot weather, drop those windows down to about 3 inch opening, turn fan on high speed and let god's physics do the rest.
