Aux Compressor: Filter Bowl Repair

by Steve and Michelle 2003 U320 40′

The filter bowls for our aux compressor.  Steve discovered the condensation bowl was leaking (the fitting that the pop-off valve at the bottom of the bowl was actually cracked completely through and came apart in his hands).  There were also cracks in the base of the bowl itself.  He found microcracks and corrosion in the desiccant bowl, including the upper filter (which you wouldn’t see unless you completely removed the filter housing, not just the bowl).
