HC-264A Air Compressor

I. Application and Applicable Scope

This series of air compressors is primarily used for starting large and medium-sized ships and marine diesel engines, and can also serve as compressed air sources for other industrial sectors and pressure testing applications.

II. Structural Type and Characteristics

This series of air compressors adopts a vertical, water-cooled, two-stage compression design, featuring excellent cooling, balanced pressure, and adjustable oil pump pressure. It can operate reliably under specific ship conditions.

Note: The automatic control system can be configured according to customer requirements, with self-control functions including automatic start, automatic stop, automatic unloading, low oil pressure alarm, high-temperature ultra-high alarm, and low water pressure alarm.
