OK, new bath fans. Top quality Panasonic 140 and 110 CFM fans. Really nice. So quiet you can barely tell they are on.
The morons who built my house ran 3 inch lines into the soffit. No vent. Got to fix that. I would prefer not putting J-Vents through the roof on the front of the house and well, I really should not be on the roof any more.
So, bought a 4 to 6 inch soffit vent for bath fans from Home Depot. Actual opening was less than the equivalent of a 3 inch duct. Dropped airflow to almost nothing. ( I am running 4" on the 110's and 6 on the 140) . Junk. Took them back. Bought a very expensive one , 4 to 6 inch spec, online that blows sideways so it does bot draft back into the attic. Good idea. Quality so bad the damper binds and won't close. Drops the airflow in half. Bought another that looked better from Lowes. Springs on damper were so stiff, the 110 CFM fan could not open them. More crap.
Why do companies make this stuff that flat does not work for the intended use? Do most people just put them up and not know they don't work? I explained to Home Depot the product by definition could not work as intended and all they wanted to know is if they were still unused and able to re-sell!
Not sure what I am going to do. I guess roof J vents on the back for the two small fans, but that much duct for the big fan would be a serious drop. Hate to put it on the front of the house, but about out of options. That is IF I can get a vent that is not garbage itself. Not impressed with the ones from Blue and Orange.
