Scavenge Line
The scavenge line runs from the combined orifice/drop tube in the separator tank, to the orifice
fitting located in the airend.
Examine the orifice, check valve and hoses at every service or in the event of oil carryover into
the discharge air.
It is good preventative maintenance to check that the scavenge line and tube are clear of any
obstruction each time the compressor lubricant is changed as any blockage will result in oil
carryover into the discharge air.
