Lifebreath Air Exchanger Vibration

Postby Junesden » Wed Mar 28, 2012 11:03 am

Hi all. Just bought a house with a Lifebreath Air Exchanger that vibrates so badly it sounds like a freight train against an interior wall. The Lower fan unit spins freely and the vibration is not felt at that piece but the whole unit vibrates. Is it the motor or a shaft? Could it be just the fact that it's pinned to a 2X4 wall studs? The unite id 10 years old but operates properly.

It does it while it's running.... The out of balance sounds right... How does one fix that?

If you are certain the blower is out of balance (and it sounds like it is), you can go buy a new blower wheel. I am assuming that's the type of blower you have (squirrel cage, not a fan blade). Many times the blower wheel will throw a balance weight. It's usually more cost effective to simply replace the blower wheel. I have yet to find anyone who will balance them, not that it should be difficult with the right equipment.

The trick is getting the old blower wheel off. Many times you need a wheel puller which is a tool much like a gear puller. Once off, take it to an HVAC supply store (Johnstone, McCalls) and they should be able to match it.
