Engine
The compressor is driven by a liquid-cooled diesel
engine.
The engine's power is transmitted to the compressor
through a gear box.
To meet the demands of Stage V Emission
Legislation, the engine is equipped with a diesel
oxidation catalyst, a diesel particulate filter, and a
selective catalytic reduction system. The particulate
filter is standard certified as spark arrestor.
Compressor element
The compressor casing houses two screw-type rotors,
mounted on ball and roller bearings. The male rotor,
driven by the engine, drives the female rotor. The
element delivers pulsation-free air.
Injected oil is used for sealing, cooling and
lubricating purposes.
Compressor oil system
The oil is boosted by air pressure. The system has no
oil pump.
The entire oil system is equipped with screwed oil
hoses to ensure higher quality and less failures.
The oil is removed from the air, in the air/oil vessel
first by centrifugal force, secondly by the oil separator
element. A spin-on oil separator assures for quick
service.
