4.5.4. FILTER SYSTEM P41 (OPTION)
PURPOSE AND SHORT DESCRIPTION
The Mariner 320 compressor units can be fitted with filter
system P41 as an optional extra instead of the standard filter
system P31. The difference is a much higher filter cartridge
life time due to the longer filter housing and cartridge. In the
standard version, filter system P41 is not fitted with the
SECURUS monitoring systeml.

Filter system P41 (Abb. 44) consists of:
• Separator with final pressure safety valve
• Non-return valve between separator and purifier
• High pressure purifier
• SECURUS sensor head
• Venting valve with pressure gauge
• Pressure maintaining/non-return valve
The system is integrated into the compressor unit, i.e. the
filters and other components are mounted on the frame, the
pressure maintaining valve is situated at the filling panel. If
the SECURUS monitoring system is provided, the breathing
air regeneration process and the degree of dryness of the air
are continuously monitored during the regeneration process
by measuring the cartridge saturation within the filter car
tridge.
Unlike other filter systems the SECURUS filter system ensures
continuous monitoring of the breathing air purification para
meters while the air is still in the regeneration process. The
influences of
• ambient temperature
• ambient humidity
• temperatures of the compressor and regeneration system
are taken into consideration.
The exchangeable SECURUS cartridges are designed for
• drying of air
• adsorption of aromatic components (aerosols)
• partial conversion of CO into CO
2
• partial adsorption of CO

The quality of the breathing air produced conforms to the
national and international
• DIN EN 12021
• STANAG 1079 MW
• British Standard 4001
• US CGA Spec. G.7.1
• Canada CSA Standard Z 180.1
• Australian Army Standard 5017
It is impossible to exceed the cartridge utilization time since
a preliminary warning message indicates the approaching
saturation of the cartridge. Depending on the size of com
pressor used, the prewarning message will appear between
1 and 7 hours prior to cartridge saturation. If the cartridge is
not replaced after indication of the preliminary warning
message, the SECURUS filter system will automatically shut
down the compressor as soon as the cartridge has been ex
hausted. The compressor cannot be turned on as long as no
cartridge has been inserted.
The SECURUS filter system operates in the FAIL-SAFE mode:
the compressor will be shut down if the circuit between the
control unit and the sensor is interrupted.
As soon as the preliminary warning mess
age appears or, at the latest, after the
SECURUS monitoring unit has shut down
the system, the cartridge must be
changed.
Final Separator
The air leaving the final stage is cooled in the after-cooler to
approx.10 to 15
°C (18-27 °F) above ambient temperature
and then enters the oil and water separator (Abb. 45). The
oil and water separator is standard for all industrial com
pressors and part of the breathing air purification system and
separates reliably liquid oil and water particles from the com
pressed air.
