Topic tags/keywords: question

This may seem like a simple question to many but I am looking for a used squirrel cage fan and don’t know where to start. Free would be great but I doubt I could be that lucky. Any suggestions?
Thanks, maryetta

Check with HVAC people.. They will usually give you a squirrel cage from an old unit they have replaced.

Gary is right, that is how I got the one that used to build my air cleaner.

I assume that you’re looking to build an air filter. Save yourself some aggravation and make sure when you ask for the fan from an HVAC outfit, that you know how much CFM your square footage dictates and ask for that size or greater. If you start out with too small of a fan you’ll be disappointed in it’s efficiency.

Also look out for the volts. An electric unit is 220V and you will need heavy wire to power it. A gas furnace has a 110V motor and you can run it off an existing circit.

The Heating and cooling companys usually have a pile of dead units out back. I had to by a start capacitor for mine but fairly minor deal.

I actually ran a seperate circite for mine with a switch by the door and hung it in the gable end to move air thru the shop in the summer.

Good luck

I work in the HVAC industry and sorry to be the barer of bad news but HVAC companies do not usually keep old units just laying around, at least none of the ones I know of. Although you may get lucky. If you do happen to find one you will want to build some type of enclosure. Left to run open on both ends these thing tend to start to free wheel and can ruin the motor, they need some restriction.

Not sure how big of one you are looking for but I used one from a bathroom vent fan for a finishing room window filter. Presumably the contractors and bathroom remodelers might have them.

Have your say...
