AIR / OIL SEPARATOR
- This device provides the final (2%) of the air/oil separation - typically 2ppm oil
content at the final discharge of the compressor package. It is housed in a removable spin-on cartridge.
Its high level of performance may be affected by the following conditions:
·
Compromised media (e.g., ruptured).
·
Contaminated media (e.g., vanish, moisture, inadequate oil type).
·
High oil level in oil sump.
·
Blockage of oil return orifice.
·
Abnormally frequent or fast depressurization cycles.
Oil separator element life cannot be predicted; it will vary greatly depending on the conditions of
operation, the quality of the oil used and the maintenance of the oil and air filters. The condition of the
separator can be determined by pressure differential or by inspection.
Separator Pressure Differential
- The pressure drop across the separator is equivalent to the difference
between the two (2) pressure sensors in use:
·
The pressure differential value may be calculated by subtracting the system pressure value from
the compressor discharge pressure value.
·
A pressure differential of 8psi will trigger a service advisory to change the element.
·
A pressure differential of 15psi will trigger a system shutdown.
Using an oil separator element at excessive pressure differential can cause
damage to equipment. Replace the separator when the “Change Separator”
advisory appears.
OIL FILTER, AIR/OIL SEPARATOR ELEMENT or OIL SCAVENGE RETURN ORIFICE INSPECTION
PROCEDURE
1. Remove the spin-on element.
2. Clean the gasket seating surface of the head.
3. Inspect the element internals by shinning a light unto the media surface. If signs of contamination
(dirt, rust, varnish, etc) or damage is evident, replace the element.
4. In case the inspection involves the air/oil separator element, refer to Figure 9- 6, Page 58, for the
location of the oil scavenge return orifice. Insert a drill bit smaller than the 1.1mm (.0039") orifice
diameter to clear any debris away. If the orifice opening is damaged or cannot be cleared, replace it.
5. Before reassembly, coat the element gasket with the same lubricant used in the unit.
6. Screw on until gasket makes contact. Hand tighten 1/3 to 1/2 turn extra.
7. Run the unit and check for leaks.
