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.

Page 5 3rd Edition, Rev 0 Chg 6
2.1.3 Manual Condensate Drainage
The condensate must be drained from the oil and water separator before changing any cartridge, before
beginning each filling procedure and in the absence of an Automatic Condensate Drain (ACD) system,
every fifteen minutes during the filling procedure. This is done by slowly opening the condensate drain
valves. They are opened approximately 1/3 of a turn to the left and held open until the condensate is com-
pletely drained. The condensate drain valves close by spring pressure but if necessary may be tightened
by hand to ensure they are completely air tight.
2.1.4 Model, Serial Number and Part Number Identification
2.1.4.1 Compressor Dataplate
The model number, date of manufacture and serial number can be found on the compressor unit identifi-
cation plate in the main electrical enclosure and frame.

2.1.4.2 Purification System Dataplate
Refer to the compressor unit purification system data plate (Figure 2-3) on the compressor front to deter-
mine your purification system model and specifications.
2.1.4.3 Cartridge Installation Dataplate
The function performed by each chamber in the purification system is determined by the type of cartridge
installed in that chamber. Refer to the cartridge installation data plate on the chamber to determine the
purpose and part number of the cartridge installed in that chamber. (Figure 2-3).

2.1.7 Cartridge Operating Life
Every Bauer Purification System is designed to process a certain volume of air before the cartridges
require replacement. By using special test equipment that measures the quality of air at the outlet any
quality reduction may be detected. However as most compressor owners do not have this test equipment
the recommended method of determining cartridge operating life is to maintain a written record of the
volume of air processed by the purification system.
Each Bauer compressor block is rated to produce a standard volume of air per minute and by using this
number and the air processing capability of the purification system it is possible to calculate the maxi-
mum operating hours before the cartridges need to be replaced. See Paragraph 2.1.7.1 for the method of
determining this figure.
The ambient air temperature and its ability to cool the compressor will effect the operating life of the car-
tridge. See Paragraph 2.1.7.2 for the method of calculating this adjustment factor.
The optimum place to measure the temperature is at the inlet to the final separator as this best reflects the
temperature of the air as it enters the chambers. Experience has shown that this temperature is approxi-
mately 18 °F above the ambient temperature. Therefore for the purpose of calculating cartridge operating
life use the Ambient Air Temperature plus 18 °F.
A form titled Air Purification Cartridge Operating Hours is found in Paragraph 2.1.7.3 and in the
Appendices. It is used for recording the ambient temperature, operating time and adjustment factor. It

is suggested that it be copied, placed in a protective folder and kept with the unit to record the adjusted
operating hours. An example of how this form is used is shown in Figure 2-5.
2.1.7.1 Calculating the Maximum Cartridge Operating Hours
1. From the purification system data plate (See Figure 2-3) on the purification chamber determine the
Air Processed (cu.ft.)
2. From the paragraph titled Compressor Specifications in the instruction manual for your compressor
unit determine the Charging Rate in SCFM of your compressor.
3. Divide the Air Processed by the Charging Rate to obtain the Maximum Operating Time in minutes
4. Divide the Maximum Operating Time in minutes by 60 to obtain the Maximum Operating Hours.
5. Record the answer on the Air Purification Cartridge Operating Hours form.
2.1.7.2 Calculating the Adjusted Cartridge Operating Hours
1. Using the Air Purification Cartridge Operating Hours form record the Date, Operating Hours and
Ambient Air Temperature plus 18 °F.
2. Using either the graph or the chart in Figure 2-4 determine the Correction Factor.
3. Divide the Operating Hours by the Correction Factor and record it under the column labeled Today.
4. Add the hours recorded in Today to the previous Total and record it as the current Total.
5. When the Total approaches the Maximum Operating Hours replace the Cartridges.

CHAPTER 3: SINGLE CHAMBER PURIFICATION SYSTEMS
3.1 Applicability
This chapter applies to Bauer Purification Systems P0 and P31 Only.
3.2 P0 Purification System Description
The P0 Purification System consists of a separator and a cartridge chamber. In the separator surround-
ing the cartridge chamber, liquid oil and water particles are separated from the compressed air by a pipe
nozzle. Residual oil and water particles are then removed by the filter cartridge and the air leaving the
P0 Purification System is free of water, oil, taste and smell.

3.2.1.2 Chamber Replacement Interval
The maximum number of load cycles for the P0 Purification Assembly is 45,000 if operated at 5,000 psi
(300 bar) or 63,000 if operated at 3,200 psi (225 bar).
If the number of load cycles of four per hour (i.e. the condensate is drained every fifteen minutes) is not
exceeded then the maximum number of operating hours before the P0 Purification System must be
replaced is 11,125 hours at 5,000 psi (300 bar). To avoid exceeding the maximum number of load cycles
the operating hours should always be recorded.
NOTICE
The used filter cartridge must be disposed of in accordance with local regulations.
^WARNING
The P0 Purification System is subject to dynamic loading. It is designed for a certain number of load
cycles. A load cycle equates to an abrupt pressure loss caused by draining the condensate.
The P0 Purification System must be replaced after reaching the maximum number of load cycles, other-
wise the housing may fail due to material fatigue.
