Maintenance

Scavenge Line

The scavenge line runs from the combined orifice/check valve at scavenge tube in the
separator tank to the fitting located in the airend.
Ensure the scavenge line and scavenge tube are clear of any obstruction. Refer to the
Maintenance Schedule for recommended servicing intervals. Any blockage will result in oil
carryover into the discharge air.

Compressor Oil Filter

Refer to the Maintenance Schedule for the recommended servicing intervals.

Removal

Do not remove the filter(s) without first verifying the compressor has
shutdown and the system has been completely relieved of all air
pressure. (Refer to SHUTDOWN in the Operating Instructions Section in
this manual).
Clean the exterior of the filter housing and remove the spin-on element.

lnspection

Inspect the oil filter head to ensure the gasket was removed with the oil filter element. Clean
the gasket seal area on the oil filter head.
If there is any indication of the formation of varnishes, shellacs, or
lacquers on the filter element, it is a warning that the compressor
lubricating and cooling oil has deteriorated and that the oil should be
changed immediately. Refer to Lubrication Section in this manual.
Installing a new oil filter element when the old gasket remains on the filter
head will cause an oil leak and can cause property damage.

Reassembly

Clean the filter gasket contact area and install the new element. Tighten until the gasket makes
contact with the filter housing. Tighten an additional 1/2 to 3/4 of a revolution.
