CHAPTER 2: PURIFICATION SYSTEM
2.1
Introduction
The purpose of all Bauer breathing air purification systems is to remove carbon monoxide, oil, water,
taste and odor from the compressed air stream before final delivery.
The purpose of all Bauer industrial air purification systems is to remove oil and water from the com-
pressed air stream before final delivery.
The quality of gas produced by the compressor is directly related to the quality and temperature of the gas
taken in by the unit. Intake gas should as close as possible to 50 °F (10 °C) and cleanest available and as
dry as possible. Bauer compressors normally add approximately 18 °F (10 °C) to the intake gas tempera-
ture. The purification cartridges perform their best at approximately 68 °F (20 °C). Adequate ventilation
enhances the quality and life of the purification cartridges.
2.1.1
General Purification System Procedures
1. Keep an accurate record of operating hours to ensure exact attention to maintenance intervals
2. Change all cartridges before reactivating a compressor unit that has been out of service more than
three months. Leave cartridges in the unit as long as it is out of service.
3. While out of service keep all condensate drain valves closed. Maintain a pressure of 700 - 1,100 psi
(50 to 80 bar) within the system to prevent moisture from entering the compressor and purification
system.
2.1.2
Chamber Safety Bore
The chambers in all Bauer purification systems are designed to prevent pressurization if the cartridge is
missing, not seated properly or damaged (Figure 2-1 & Figure 2-2). Without a cartridge properly in place
the safety bore is not sealed, the air escapes into the atmosphere, no pressure can be built up and thus it is
ensured that unfiltered air is not supplied to the consuming device. If air is escaping from the safety bore
remove and check cartridge. If necessary replace the cartridge or O-rings.

WARNING
Industrial Air Purification System cartridges do not remove Carbon Monoxide
and must not be used in breathing air applications.
