A marine 30 bar piston air compressor is a heavy-duty, reciprocating compressor specifically designed for use on ships and offshore platforms. It delivers medium-to-high pressure compressed air (30 bar) for critical onboard systems such as main engine starting, control air, and auxiliary equipment. Built to withstand harsh marine environments, it features corrosion-resistant materials, compact design, and compliance with international marine classification society standards (such as DNV, ABS, LR, and CCS).
Marine-Grade Construction
Corrosion-resistant materials (such as coated cast iron or stainless steel components) ensure long service life in saltwater environments.
Reliable Engine Starting
Delivers stable 30 bar starting air for main and auxiliary diesel engines, meeting international maritime requirements.
Compact & Space-Saving
Optimized footprint for engine rooms and confined spaces onboard vessels.
Compliance with Classification Societies
Designed to meet standards of DNV, ABS, LR, CCS, and other major marine classification bodies.
Heavy-Duty Piston Design
Built for continuous operation with robust wear parts, ensuring durability under demanding marine conditions.
Easy Maintenance
Accessible components and simplified maintenance procedures reduce downtime during port calls or at sea.
Air-Cooled or Water-Cooled Options
Flexible cooling configurations to suit different engine room layouts and operating conditions.
