Maintenance
Element Life
Generally, filter element life is from four to five months. Very few filters last more than
twelve months. Factors influencing filter life are high flow rates, high compressor rpm,
high compressor operating temperature and worn compressor piston rings. These
factors allow more oil to enter the air system and reduce the life of the filter.
Installation
The 908-063 is an inline polyethylene-tubing supported air filter that is designed to be
used with 1/4-inch (6mm) or 3/8-inch (10mm) polyethylene air tubing . An optional
manual shut-off valve may be installed, as desired, at the inlet to each filter to shut off
the supply air while the filter element is being changed.
If, during filter replacement, the loss of the air supply to the system is undesirable for
about five minutes or so, a manual bypass should be installed around the filter.
