CHAPTER 5:
PURIFICATION SYSTEM
5.1
General
The purpose of all Bauer industrial air purification systems is to remove oil and water from the com-
pressed air stream before final delivery. For this reason Bauer purification systems are installed immedi-
ately before the compressed air delivery point.
5.1.1
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 to 1,100
psi (50 to 80 bar) within the system to prevent moisture from entering the compressor and purifica-
tion system.
5.1.2
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 (See Figure 5-1). 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 therefore must not be
used in breathing air applications
