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.

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)

Regulating Valve

Regulates the effective pressure in the air receiver

Provides regulating pressure to :– unloading valve

=> regulates the air inlet according the air demand

– speed regulator=> regulates the engine speed to reduce fuel consumption

Compressor Running Conditions

Major running conditions :

– UNLOADReceiver tank pressurized, no air being used

– LOADReceiver tank pressurized, air is being used

– BLOW-DOWNMachine stopped, blow-off of receiver pressure

Safety shut-downs– Compressor :

Compressor element outlet temperature (255ºF) – 1310 0734 67– Engine :

Coolant temperature (221ºF) Oil pressure (17psi) Low fuel level (5%) Alternator not charging Fail safe as a loose wire will result in a shut-down

Good electrical contacts are important
