Lifetime
The oil and water separator is sub
ject to dynamic load. It is designed
for a certain number of load cycles,
which originate from an abrupt pressure loss at con
densate drain (1 load cycle i.e. condensate drain = 1 de
pressurization, 1 pressurization). Acc. to no. 15 of the
annex II to the German pressure vessel regulations the
filter housing has to be inspected internally by an ex
pert after having reached half of the determined num
ber of load cycles. The inspections have to be arranged
by the operator. After reaching the max. number of load
cycles the filter assembly must be replaced, otherwise
the housing may burst due to material fatigue. Refer to
the pressure vessel operating manual delivered with
the unit.
The maximum recommended amount of four load cycles per
hour should not be exceeded. If it is possible to regulate the
operation of the unit to such a degree as to achieve four load
cycles per hour, in our opinion this would be an optimum be
tween usage and actual life.
The cycles are counted by the cycle counter of the com
pressor control unit. After the max. number of load cycles
have been reached (refer to the pressure vessel operating
manual delivered with the unit), the separator must be ex
changed.
Condensate drain
The condensate produced by the re-cooling after the com
pression process has to be drained regularly by means of the
manual condensate drain valves
• before start-up of the compressor unit
• during operation every 30 minutes, at high humidity
every 15 minutes.
For units equipped with an automatic condensate drain sys
tem refer to chapter 4.5.10.
Purifier
The filter housing consists of an anodized aluminium alloy
pipe with 100 mm external diameter. Both ends are provided
with fine threads on the inside.
The screw-in filter bottom contains inlet and outlet. For con
nector threads see specifications, chapter 1.
The upper screw connection contains a pressure resistant
bushing for the electrical connections. The coaxial cable
which leads from the sensor to the control unit is connected
to the BNC connector located there.
Filter cartridges
New filter cartridges are vacuum-packed and can be stored
for two years (refer to date on the cartridge). A defective vac
uum package cannot protect the cartridge appropriately
against environmental influences during storage. Should the
package be damaged, do not use the cartridge.
To avoid any danger to your health or damage to your unit,
change used up cartridges in good time.
Never fill used up cartridges yourself! The filter material was
chosen specifically by BAUER-KOMPRESSOREN for each kind
of application.
Pay attention to cleanliness an hygiene when changing the
filter.
The cartridge tube is made of aluminium. Cover and bottom
consist of pressure diecast aluminium. The cartridge cover
contains the sensor for the monitoring function and the clip
to facilitate changing of the cartridge.
Different cartridges are available depending on the required
air quality. See table below.

Maintenance
-
Depressurize system before starting any maintenance
work. The filter line can be vented manually with the
venting valve, wait until the pressure gauge reads zero.
-
Dry inside of filter housing with a clean cloth before in
stalling new cartridge and check for corrosion.
-
Lubricate threads and O-rings as well as end of cartridge
with both o-rings with white petrolatum. Apply sparingly.
See chapter 7.
-
Observe number of operating hours as indicated on hour
meter to ensure exact attention to the maintenance in
tervals.
