Unloading Valve
Opens and closes the air inlet to the compressor element.– Open position at load condition
=> Air demand.
– Closed position at no load condition=> No air demand.
Valve is controlled by the regulating pressure.

Check Valve
Check valve is integrated in the Unloader XAS 185 JD compressor.
Closed when the compressor is stopped.
The air receiver is pressurized, which would result in a reverse air flow. the check valve prevents this.

SeparatorElement
Minimum Pressure Nozzle
Guarantees a minimum pressure in the receiver tank (approx. 45 – 60 psi)
Minimum pressure is required to guarantee a continuous oil supply to the element.

When changing the separator element the retainer must be cleaned
Also works as ground
* Centrifugal force removes about 85% of the oil
Change of direction, about 99% of the oil
After separator element at discharge will be 3 to 5 PPM.
**Make sure the scavenge line runs ALONG SIDE the air outlet tube and NOT in the air outlet**
Oil Separator
Classic Reasons For Oil Carryover– Over filled receiver– Plugged scavenge line or restricted orifice– Wrong type of oil (no anti foam agent and anti-corrosion additives)– Shut down with air outlet valves open (Only On XAS 185)– Scavenge tube installed improperly (in outlet tube)– Used incorrectly for application (Sandblasting)
