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.

Diesel engine

The standard Hatz diesel engine ensures reliable, low-maintenance performance with low operating costs.

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.
