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 4.1.7.1 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 4.1.7.2 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 4.1.7.3 and in the
Appendices. It is used for recording the ambient temperature, operating time and adjustment factor. It
