Details & Features
Built for the toughest environments, the MARINER handles both continuous operation and challenging conditions with ease. The three- or four-stage design and industrial roller bearings ensure long service life and smooth operation. The integrated protective frame provides reliable protection and allows easy accessory expansion. The MARINER is equipped as standard with the high-performance P 31 filter system, delivering the highest breathing air quality. Mobile, powerful, and corrosion-resistant, the MARINER is ideal for professional applications in diving, marine operations, fire services, and paintball.
Compressor block
Our compressor blocks are based on decades of experience and development. An efficient air cooling system with large coolers and finned cylinders ensures optimal cooling. Robust industrial roller bearings, pressure lubrication, and fine oil filters minimize wear. Dynamically balanced drive units ensure smooth operation and long maintenance intervals.
P 21 filter system
The integrated P 21 filter system with oil and water separator as well as pressure-retaining non-return valve ensures reliable breathing air in accordance with DIN EN 12021¹ when using original BAUER filter cartridges. A type-tested, sealed final pressure safety valve ensures maximum operational safety. The processable air volume is 140 m³.¹ Applies when properly maintained and installed, and if CO₂ limits in accordance with the standard are not exceeded.
P 31 filter system
The P 31 filter system with integrated oil and water separator as well as a pressure-retaining non-return valve ensures reliable breathing air purification in accordance with DIN EN 12021¹ when used in combination with original BAUER filter cartridges. A type-tested, sealed final pressure safety valve ensures an especially high level of operational safety. The processable air volume is 600 m³.¹ Applies when the system is properly maintained and installed in accordance with the operating manual, and provided that the CO₂ concentration in the intake air does not exceed the limits defined in the applicable breathing air standard.
Crash frame incl. carrying handles
The corrosion-resistant crash frame provides additional protection and space for accessories such as compressor control or larger filter system. The carrying handles ensure easy and comfortable transport.
Filling device
The filling device consists of a flexible "UNIMAM" high-pressure filling hose and a filling valve with a final pressure gauge. The gauge allows easy reading of the filling pressure and is reliably protected against damage by a robust rubber coating.
Filling hose
The high-quality UNIMAM high-pressure filling hoses are made of food-grade, durable material and provide maximum flexibility during handling. Swiveling hose connections allow for quick, easy, and safe connection of the filling valve to the breathing air cylinder.
Motor rocker with belt tensioner
Thanks to the integrated motor rocker with belt tensioner, no retightening of the V-belt is required anymore.
Options
P 31 filter system
The P 31 filter system with integrated oil and water separator as well as a pressure-retaining non-return valve ensures reliable breathing air purification in accordance with DIN EN 12021¹ when used in combination with original BAUER filter cartridges. A type-tested, sealed final pressure safety valve ensures an especially high level of operational safety. The processable air volume is 600 m³.
¹ Applies when the system is properly maintained and installed in accordance with the operating manual, and provided that the CO₂ concentration in the intake air does not exceed the limits defined in the applicable breathing air standard.P 41 filter system
The P 41 filter system with additional oil and water separator as well as pressure-retaining non-return valve ensures reliable breathing air in accordance with DIN EN 12021:2014¹ when using original BAUER filter cartridges. A type-tested, sealed final pressure safety valve ensures high operational safety. The processable air volume is 1,550 m³.
¹ Applies with proper maintenance, installation according to the operating manual, and when using the BAUER B-AEROGUARD if the CO₂ concentration exceeds the standard limits.B-TIMER filter cartridge monitoring
The unique B-TIMER minicomputer displays the operating hours and the current filter cartridge saturation in real time. A prominent blinking signal indicates when a cartridge change is due – including the corresponding order number. This ensures the filter capacity can always be used optimally.
B-SECURUS filter monitoring
The B-SECURUS system monitors the saturation of the filter cartridge(s) by measuring the moisture level in the molecular sieve and provides a timely indication when a cartridge replacement is required – either on the display or via the control unit. Once saturation is reached, the system automatically shuts down the unit. The B-SECURUS filter monitoring system can only be used in conjunction with the P 41, P 61, or P 81 filter systems, as well as the external BAUER filter systems.
First-stage separator
For operation in humid ambient air, such as in tropical regions or when handling moist gases, a separator is recommended after the first compression stage. It reliably discharges the increased amount of condensate and minimizes its entry into the compressor oil.
Compressor control (PROFI-LINE)
The electrical control with monitoring electronics shuts down the compressor at final pressure, records operating hours and oil pressure, and displays the current status. It also enables fully automatic operation.
Automatic condensate drain with auto shut-off at final pressure
The automatic condensate drain empties the intermediate and final separators automatically during operation and shutdown – for greater convenience and less effort. In addition, the compressor shuts down automatically at final pressure. For maximum safety, all electrically driven models are built according to DIN EN 60204 and feature a compact control system with control transformer – CE-compliant and operationally safe.
Changeover device PN 300/200 bar
The PN 300/200 bar changeover device allows filling of cylinders with different operating pressures.
Additional filling device PN 200 or PN 300 bar
An existing filling connection can optionally be expanded by one or more additional connections with filling hoses of variable length.
Trolley set
The trolley set enables easy and effortless transport of mobile compressor units. Equipped with pneumatic wheels, it ensures maximum mobility.
Intake telescope
The intake telescope allows relocating the intake area of compressor units to a place with clean ambient air. It is especially recommended where the installation site has elevated concentrations of pollutants such as CO or CO₂.
