Bubba and I inspected the instrument air compressors at both end stations and the corner.

The two end stations have failed vibration isolators. Bubba is checking our inventory of spares.

The corner station is in good condition - and has been mounted in a different fashion.

Attached are two photos; shorted.jpg is one of the end station units, notshorted.jpg is the corner.
