Fasco A082 Combustion Blower replacement for Enviro Exhaust fan

[Don2222]

Hello

My friend has an Enviro EF-2i with the OEM High Pitched Wine combustion blower. Some people are real sensitive to that!

Well combustion blowers look different but have the same mounting. In this case the box of Fasco Generic A082 blowers I got still worked. Removing the Enviro blowers 6 inch hub and putting it on the new one keeps the nice slotted mounting holes for easy reassembly. See pic

I almost got the old impeller off by removing the set screw and heating the hub. It moved up quite a bit but I could not finish removing it. However not the best way! So in the interests of saving time I cut the shaft again.
Then I painted the outside of the the hub with Hi temp flat aluminum and sprayed the inside with the graphite spray. Then reamed out the mounting holesin the A082 to 17/64" and with washers under the new serrated bolts BINGO the blower mounted right on!

Then I topped it off with a hand made Lytherm gasket cheap!

These blowers have oil plugs and an oil cap! With some 3-1 oil every year they can last a long time!

NOTE: fits Breckwell, Whitfield, Travis, Lopi, country, Glowboy, and many others, some simple modifications to this unit may be required for bolt up pattern. LOL -- Just some drilling in many cases!

This blower with a little work, will fit many stoves!

Does anyone else re-use the old hub on their exhaust blower for that OEM look?

Last pic is the Enviro Exhaust Blower with the high pitch wine!

Interesting. I have a EF-2i insert just about ready to install, and now I will have to fire it up again and listen for an objectionable "high-pitch whine" from the combustion fan. (Open-frame motor, looks original.) Now would be a better time to proactively replace it. Something to add to the list, after a new burn pot grate, and convection fan control pot.

Hello Chamas
Is it a brand new EF-2i insert?
It is a really good stove! The only objection is the high pitch exhaust fan noise!

When running 24/7, I just learned that when the fire turns orange after 2-3 days it is time to brush out the burn pot on it.

Don't forget the pics after the install please!

the new enviro motors spin at a true 3000rpm under load. the fasco A82 is lucky to get 2500rpm when hot ans will not fit in all enviro stoves, such as the windsor, milan and empress that have the angled exhaust housing. the fasco is a decent motor that works in many applications but enviro stoves tend not to show much issue until they are hot...a weakness of that motor.

Do you have one of these to check it?

No, it's quite old. I have some pics of it in this post from Feb. 2012:

So maybe the replacement combustion motor does not whine because it does not run as fast as the orig. open frame motor?

Hi Scott
The description here says the OEM blower fits all including the windsor, milan and empress.

Is there something different on this Fasco A082 that would not fit these stoves?

They are both supposed to be 3,000 RPM however the Fasco A082 replacement has a nice protective black case so that may help with the wine. They also seem to be constructed differently. Sometime I would like to get a tachometer for testing. It might be a good way to see if an aging blower needs replacement. http://usatoolsinc.com/smallenginetachometeresi328.aspx?gclid=CP-Co4rPirICFYVQOgoduA0A6w

Hi Chamas

Here is a video of what this OEM Enviro combustion blower made by Jake Inc. sounds like!
It has the high pitched wine and bearing noise so it really needs replacement to make it through the season!

The casing of the motor hits the side access panel just enough to rattle. Look at your link...the part that says MOST MODELS doesn't mean ALL MODELS. Not all of the Windsor, Milan, Empress's have the angled position...strike the Milan...that is an insert and wouldn't matter. dough!

I see. Thanks
