Marine Insight: 30 Bar Air Compressor

Marine Industry Demand: Critical Role of 30 Bar Air Compressors for Vessel Safety

The 30 bar air compressor represents a fundamental safety-critical system aboard modern commercial and offshore vessels, directly supporting compliance with stringent international maritime regulations, particularly SOLAS Chapter II-2. These high-pressure units are indispensable for energizing essential emergency and operational systems where failure is not an option. Primary applications include initiating emergency shutdown systems for machinery and cargo handling, providing the motive force for fixed firefighting systems such as CO2 flooding mechanisms, powering critical pneumatic controls for main engine starting and maneuvering, and supplying air for lifeboat davit operations. The consistent delivery of clean, dry, oil-free air at precisely 30 bar (approximately 435 psi) is mandated to ensure these systems activate instantly and function reliably during emergencies, directly safeguarding crew, vessel integrity, and the marine environment. Substandard or undersized compressors introduce unacceptable risk; insufficient pressure or volume can lead to delayed system response or complete failure during critical events, potentially escalating incidents with catastrophic consequences. Consequently, vessel operators and classification societies demand compressors engineered to exacting marine standards, featuring robust construction, comprehensive safety interlocks, and rigorous certification.

Technical Specs & Approval

The 30 bar marine air compressor offered by Hangzhou Star Marine Technology Co., Ltd. is engineered to meet the rigorous demands of maritime operations, ensuring reliable performance in auxiliary and emergency systems onboard commercial, offshore, and naval vessels. Designed for high-pressure applications, this compressor delivers a maximum discharge pressure of 300 bar (30 MPa), making it suitable for starting large diesel engines, pneumatic tool supply, diving systems, and high-pressure air storage. Constructed with marine-grade materials and compliant with international classification society standards, including CCS, ABS, DNV, and LR, the unit ensures operational safety and longevity in corrosive and high-humidity environments.

This compressor utilizes a multi-stage compression process to achieve optimal efficiency and reduced thermal stress across components. The flow rate is engineered to balance rapid air delivery with energy conservation, supporting continuous duty cycles without overheating. Depending on the model configuration, free air delivery ranges from 1.8 to 6.5 m³/min, allowing scalable integration across vessel sizes—from medium-duty workboats to large cargo and offshore support vessels. The system is driven by a TEFC (Totally Enclosed Fan Cooled) electric motor, available in 380V/50Hz or customized voltage/frequency options to match onboard power grids.

Cooling is managed through an efficient forced-air system, with finned intercoolers and aftercoolers integrated between stages to minimize discharge air temperature and condensate formation. This contributes to improved air quality and reduced load on downstream filtration and drying units. The compressor frame is mounted on anti-vibration rubber dampers to minimize noise transmission and mechanical fatigue in dynamic sea conditions. Additional features include automatic condensate drains, pressure-safety valves, and a centralized control panel with digital monitoring of pressure, temperature, and operational hours.

The unit is supplied as a skid-mounted assembly for simplified installation and includes all necessary gauges, valves, and protective enclosures. Optional configurations include sound-attenuated enclosures for noise-sensitive areas and integration with remote monitoring systems via Modbus or CANopen protocols. All models undergo 100% factory testing, including pressure, leak, and endurance trials, to ensure compliance with ISO 5388 and MSC.338(91) standards.

Packaging & Logistics

All marine air compressors, including the 30 bar models, are packaged to meet international shipping standards and ensure safe transit under diverse climatic and handling conditions. At Hangzhou Star Marine Technology Co., Ltd., we prioritize the structural integrity and environmental resistance of our packaging to protect critical marine equipment during export logistics. Each 30 bar air compressor is secured within robust wooden export cases that comply with ISPM 15 (International Standards for Phytosanitary Measures No. 15). This internationally recognized regulation mandates the treatment of wood packaging material to prevent the spread of pests and diseases across borders. Our wooden cases are constructed from heat-treated plywood or solid wood, stamped with the official ISPM 15 mark, and designed to withstand stacking, moisture exposure, and rough handling during sea freight.

For added stability and protection during containerized transport, the wooden cases are mounted on heavy-duty steel pallets. These pallets provide a rigid base that facilitates safe handling via forklifts and cranes at ports and warehouses. The combination of steel-reinforced pallets and ISPM 15-compliant wooden enclosures ensures that the air compressor remains immobilized and shielded from impact, vibration, and environmental contaminants throughout the shipping journey. All internal surfaces in contact with the equipment are lined with anti-corrosive VCI (Vapor Corrosion Inhibitor) paper, and desiccant packs are included to mitigate moisture accumulation during prolonged sea voyages.

Prior to dispatch, each packaged unit undergoes a final inspection to verify sealing integrity, labeling accuracy, and compliance with export documentation. The exterior of each case is clearly marked with stenciled and adhesive labels indicating handling instructions, weight, dimensions, port of destination, and customer identification. Hazardous material labels are applied if applicable, in accordance with IMDG Code requirements for marine shipments.

All exports of 30 bar marine air compressors are coordinated through China’s major international ports, primarily Ningbo and Shanghai. These ports offer world-class container handling infrastructure, direct shipping lines to global destinations, and efficient customs clearance procedures. Our logistics partners are experienced in handling heavy industrial cargo, ensuring timely booking, container stuffing, and real-time shipment tracking. Standard export documentation, including packing lists, commercial invoices, certificates of origin, and bill of lading, is prepared in compliance with international trade regulations.
