QUICK-DISCONNECT
The feed hose is connected to the quick-disconnect using a barbed fitting on the quick-
disconnect. If the feed hose must be repaired, shortened, or replaced, follow the
procedure just outlined for BARB FITTINGS.
FILTER
The filter keeps moisture and dirt out of the cylinders and other components. KEISER air
systems incorporate a refrigerant dryer on the compressor. Refer to the preventive
maintenance chart for time interval for checking filters (table 1, pg. 4).
The filter on your KEISER machines is an “in line” filter. This filter cannot be
disassembled and has no drain. When the filter element is dirty, the element turns a bright
pink or red. At that point the filter must be replaced. Contact the KEISER Service
Department for replacement filters.
All filters have a directional arrow and must be installed so the arrow points in the
direction of air flow into the machine. Always decrease the resistance to zero before
starting service or repair on any machine.
-CAUTION-
IF THE FILTER BOWL IS CRACKED, IT MUST BE REPLACED IMMEDIATELY.
-NOTICE-
IF FILTER BOWL IS CRACKED, AN AIR LEAK COULD RUN THE COMPRESSOR
CONTINUOUSLY, PUTTING EXCESSIVE WEAR ON THE COMPRESSOR.
