Service Air Compressor · Compressors
Haug (Sauer) Haug SOGX 55 400/7 is a service-air compressor. It is normally installed in an engine room or utility machinery space and connected to the vessel's service or control-air distribution system through receivers and air-treatment equipment. Its purpose is to supply compressed air for pneumatic tools, maintenance, general service and other approved shipboard consumers. The existing database record states 7 bar. The machine may be reciprocating or another compressor type depending on the model; the exact construction must be confirmed from manufacturer documentation rather than inferred from the category. The exact series and model designation distinguishes compressor size, speed and arrangement from neighboring variants; delivery and operating limits must be taken from the manufacturer documentation.

What our service work and the manufacturer documentation say about keeping this model running.
Check oil level and condition, cooling-water flow, stage temperatures, valve operation, drains, separators, relief devices and non-return arrangements. Listen for abnormal knocking and compare receiver filling performance with the vessel's established normal condition. Inspect for air, oil and cooling-water leakage and confirm that automatic condensate drains are functioning. Examine drive belts or coupling components where fitted and verify guards are secure. During overhaul, inspect valves, piston rings, cylinders, bearings and coolers for deposits and wear. Refer to the manufacturer documentation for the exact pressures, clearances, valve settings and overhaul criteria.
Keep suction and discharge valve service parts, piston rings, gaskets, seals, filter elements, lubrication consumables and drain or unloader service parts recommended for the installed compressor. Critical vessels commonly require enough parts to restore one compressor after a typical valve or sealing failure. Confirm exact parts against the model and serial number.
