This technician arrived to find this make air unit with a few problems. As you can see one of the bearings is gone and the structural support of the blower, fan shaft, and bearings is nearly worn through.
The amount of rust in this unit is beyond repair.
Currently this unit is condemned. The space it use use to make up the air for was a kitchen that is now under a negative pressure due to the exhaust fans. Now occupants of the lower floor literally get sucked in...
