I will guess a Hunter.
I have had 2 that were spinning for years, just add oil from time to time,vacume the top side and clean the blades. Basic 3 speed reversible.
No remotes just pull chain
Many box stores carry Hunter as well. I suspect it has more to do with the fan being 20 years old and the quality of said fan 20 years ago compared to today. It is also entirely possible that Hunter builds in a cheaper brand just for the box stores. But I don’t know that I would risk my company’s name to bend to a box stores price point
Ditto for the Hunter. 20 years and still working well. I’ve never oiled it but maybe I will.
My guess as well. We have one installed 13 years ago and use the Hell out of it during these 115 deg. AZ summers. Quiet as a tomb and problem free.
