15-40 HP   174-580 psi  30,5-99,6 cfm


Oil Injected, Direct Coupled

Reciprocating High Pressure Air Compressors

We offer ideal air solutions for high pressure applications for marine industry.

 Advantages 

• Lightweight and robust composite cabinet provides high-performance cooling, protects the cylinder heads from impacts, and prevents the operator from coming into contact with moving and hot components.

• Ease of installation and strong components for longer uptimes and user-friendly operation.

• Safe, low-maintenance operation thanks to integrated flexible coupling


 General Features 

• PLC-based control and system monitoring with digital display panel

• High efficiency motor

• Oil trap air filtration system (Optional)

• Direct coupled


 Main Motor and Drive System

• IE3 efficiency-class electric motor

• Direct coupled with elastic coupling

• Star/delta motor starter

• Special loadless start system and automatic discharge system for loadless start

• Soft starter (optional)

Compressor Block

• Cast iron cylinder with cooling fins and special aluminium alloy cylinder heads

• High-strength cast iron sumps

• Dynamically balanced steel crankshaft and counterweight

• Special aluminium alloy pistons and cast steel connecting rods

• Specially designed concentric-type, high-capacity stainless steel suction-discharge valves


  Cooling System

• 4-stage radiator (3 stages for air, 1 stage for oil cooling)

• Cylinder and cylinder heads with cooling fins

• Cooling fan connected directly to the main motor

• Integrated oil pump driven by the main motor lubricates the pistons and pins

• Specially designed concentric-type, high-capacity stainless steel suction-discharge valves

 Controller

• Mains voltage and frequency monitoring, protection at certain limits

• Multiple compressor control for up to 8 compressors without the need for an external master compressors

• Internal ModBus communication

• Alarm log records the last 9 alarms
