Key highlights
- ✓SKY screw air end with a proprietary rotor profile and heavy-duty bearing design, as described for the water-well compressor series.
- ✓Electronic operating display covers engine speed, air pressure, engine oil pressure, discharge temperature, coolant temperature and fuel level.
- ✓Self-diagnosis, fault alarms and protective shutdown support operating supervision.
- ✓Separate oil, water and air coolers with a large-diameter fan provide thermal management for varying ambient conditions.
- ✓Multi-stage intake filtration combines centrifugal pre-cleaning, a main filter and a safety element for dusty operating environments.
- ✓Oil-air separation and lubricating-oil filtration protect the compressor air circuit and moving components; fuel filtration protects the engine injection system.
- ✓Remote network monitoring is available as an option; it is not assumed to be fitted to every machine.
Applications: Compressed-air supply for water-well drilling, matched to the required drilling air pressure and delivery.
