Integrated Design, Quality and Performance

Key Features of BAUER Compressor Technology

Clean, filtered air is essential for proper operation of the compressor. The intake to the compressor is protected by a high performance filter. Additional filtration or treatment of the air may be required for dusty environments or harsh climates.

A safety valve is installed after each stage of compression to ensure safe operation and to protect the compressor from overpressure.

Separators remove oil and water from the compressed air. All separators are made of corrosion resistant materials for long life and to prevent contamination of the compressed air.

The crankcase serves as a strong foundation for the cylinders, sturdy support for the driving gear and provides a large oil reservoir. The crankcase is completely sealed against dirt and moisture for protection of internal components. BAUER uses a sturdy cast aluminum alloy crankcase on compressor frames through the 23 series. A rugged cast iron crankcase is used on the 25 and 28 series compressor frames. The crankcase is fully encapsulated to prevent the release of oil laden air to the environment.

All BAUER compressors are pressure lubricated for reliable lubrication of internal components. A sight glass and replaceable oil filter are standard on all models.

All bearing surfaces on the driving gear use long life roller or needle bearings for reduced friction and maximum mechanical efficiency. The drive gear is supported in the crankcase with heavy duty ball bearings. The dynamically counterbalanced crankshaft provides smooth, practically vibration-free operation.

The BAUER design guarantees optimum air flow and efficiency, thus maximizing valve life. All valves are readily accessible for inspection and maintenance. Valve maintenance is inexpensive and easy to complete.

The ACD automates the drainage of the interstage and final separators. This device enhances the use of the compressor for industrial applications by eliminating the process of having to drain the separators manually. The ACD also unloads the compressor automatically at restarting. Manual valves are included to override the automatic operation of the ACD for troubleshooting.

The BAUER air cooled design is based on more than 60 years experience. All coolers are located in the direct blast of the cooling fan(s) for effective removal of the heat of compression. All cylinders and cylinder heads have large surfaces and fine ribbing for maximum heat dissipation. All coolers are made of corrosion resistant material for long life and non-contaminating service.

The BAUER design provides discharge air temperatures of only 20ºF - 40ºF above ambient temperature depending upon the model.
