i need to replace the motor on my bathroom fan. the brand name of the
fan is Aira which search of the internet reveals nothing.

in seeking a replacment motor can i just look for a similar motor with
shaft lenght and diameter (so the blade fits correctly)?? or is it
critical to also look at the RPM and current ratings?

unfortunately taking out the fan assembly to put in a new fan is not
an option i can undertake

my fan motor ratings are (and if anyone knows of a suitable
replacement i appreciate your providing that as well)

Model VSB-P90A
CCW
Stack = 0.85in
Shaft = 0.25in diameter
Shaft = 1.75in lenth


*Try giving Broan-Nutone a call (Broan.com, on the Parts page is a toll free number). I can't remember the brand, but a few years ago I needed a replacement motor for an odd brand and they had it, but it wasn't listed on their web site. The fan had a plastic housing instead of the usual metal can.

Another possibility is Grainger. They sell generic replacement motors.

As others have mentioned, you could remove the motor and take it somewhere that stock replacements and try and match it up.

I always get a new fan impeller blade as the old ones can be a PITA to remove and sometimes break in the process.

If it comes down to replacing the entire unit, go with Panasonic. Their fans are the only ones that are made for retrofitting though it is still a bit of a challenge.
