Starting Air Compressor · Compressors
The Hatlapa L 75 400/A is a high-pressure starting-air compressor. It is normally installed in the engine room connected to starting-air receivers through coolers, drains and non-return valves. It is designed for charging the stored-air system used to start main and auxiliary diesel engines. The operating principle relies on multi-stage or other approved compression of atmospheric air to the receiver pressure selected for the vessel. Compared with neighbouring models, the relevant differences are delivery, final pressure, number of stages, cooling arrangement and drive; these must be confirmed from the installed documentation rather than inferred from the model designation alone. Service and survey attention should concentrate on stage temperatures/pressures, valves, coolers, drains, oil carryover, unloaders and automatic control. For exact ratings, dimensions, tolerances, test limits and model-specific settings, refer to the manufacturer documentation for the exact figure.

What our service work and the manufacturer documentation say about keeping this model running.
Check delivery and receiver pressure, stage temperatures where fitted, cooling, lubricant condition, intake filters, valves, separators and drains. Verify automatic load/unload or start/stop control, non-return valves and safety devices. Inspect drive, coupling/belts and vibration and review receiver and dryer condition where part of the system.
Carry filter elements, valve/service kits, gaskets, piston rings or air-end seals as appropriate, belts/coupling elements, drain valves and pressure-control components. Starting-air units may justify spare valve plates or cylinder-service parts; service-air plants may require separator/dryer consumables.
