Compressor block

Bauer's 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.

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.

Diesel engine

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

Motor rocker with belt tensioner

Thanks to the integrated motor rocker with belt tensioner, no retightening of the V-belt is required anymore.
