Question: what is the diameter of the fan?
Document: The fan is very quiet now and sounds like new!
Took the old fan out, replaced the motor in just a few minutes, put it back... and it works great.
The motor/fan is very quiet but it does move a lot of air so any noise is typical air movement.
The fan was an OEM replacement, fit the frame and was easy to install. Best of all was the cheapest option.
The quickest and cheapest way to "fix" a fan that doesn't move the air anymore. Not quiet but not bad either.
It works, same quality as original unit in fan, and lasts about as long (a couple of years before the bearings dry out).
Fan is a little loud when running, however it works fine. This was a direct replacement for the original fan.
Motor and Fan Blade were new in box. Installed, and put in service, never any problems. very quite when in use too.
It was exactly what I needed and it fit perfectly in my fan housing. I could not ask for a better outcome.
Fan is easy to install and works great. Glad it is still readily available for fans over 25 years old.
Answer: yes
