Regulation
The compressor is provided with a continuous
regulating system and a blow-down valve which is
integrated in the unloader assembly. The valve is
closed during operation by outlet pressure of the
compressor element and opens by air receiver
pressure when the compressor is stopped.
When the air consumption increases, the air receiver
pressure will decrease and vice versa.
This receiver pressure variation is sensed by the
regulating valve which, by means of control air to the
unloader and engine speed regulator, matches the air
output to the air consumption. The air receiver
pressure is maintained between the pre-selected
working pressure and the corresponding unloading
pressure.
Cooling system
The engine is provided with a liquid cooler and the
compressor is provided with an oil cooler.
The top tank of the engine cooler is integrated in the
cooler to reduce the amount of connections. This
results in higher general robustness and less engine
failures.
The cooling air is generated by a fan, driven by the
engine.
Fuel system
The fuel feed lines and fuel filtration are designed in
such a way that after running the fuel tank dry, air
pockets can't reach the engine and smooth starting is
ensured.
Safety devices
A thermal shut-down switch protects the compressor
against overheating. The air receiver is provided with
a safety valve.
The engine is equipped with low oil pressure and high
coolant temperature shut-down switches.
Frame and axles
The machine is equipped with a spillage-free frame.
The base frame which is made out of a single metal
sheet, can contain up to 110% of all the liquids in the
compressor. A drain plug is installed to drain the
frame and safely capture all the spilled liquids.
The bumper is designed in such a way that it protects
the rear bottom of the frame if the machine would be
tilted on its rear.
The compressor/engine unit is supported by rubber
buffers in the frame.
The unit can be delivered with or without wheels. If
equipped with wheels it has an adjustable or fixed tow
bar with brakes. The tow bar can be equipped with a
ball coupling or various towing eyes.
The tow bar can be equipped with a jockey wheel or
support leg.

Lifting eye
A lifting eye is accessible through a rubber covered
hole at the top of the unit.
Road light system (option)
The right hand traffic road light system includes rear
lights, stop lights, direction indicators, license plate
light, fog light and rear reflector and a 7-pin connector
to connect the lights to the towing vehicle. The entire
installation is EU type approved.
Wheel chocks are included when ordering the road
light system.
