Integrated Design, Quality and Performance

Key Features of BAUER Gas Compressor Technology

(1) Intake Filter
Clean, filtered gas 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 gas may be required depending upon the quality of the gas.

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

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

(4) Crankcase
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 gas to the environment.

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

Drive Gear
All bearing surfaces on the driving gear use a 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.

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

Automatic Condensate Drain (ACD)
The ACD automates the drainage of the interstage and final separators. This device enhances the use of the compressor for heavy-duty use by draining the condensed oil and water from the interstage and final separators. A timed sequential drain mode is used to keep a balanced load on the compressor during the drain cycle. This is a key feature for ensuring long compressor life. The ACD also unloads the compressor automatically for unloaded restarting. Manual valves are included to override the automatic operation of the ACD for troubleshooting purposes.

(7) Cooling
The BAUER air cooled design is based on more than 55 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. Cooler operating temperatures result in improved efficiency in the separators and reduced oil vapor carryover to storage and to NGVs. All coolers are made of corrosion resistant material for long life and non-contaminating service. The BAUER air cooled design provides discharge gas temperatures from 20ºF to 30ºF above ambient.
