P filters: The high-pressure cartridge filter systems from BAUER KOMPRESSOREN – in use all over the world for the treatment of breathing air, industrial air, nitrogen, helium, argon and methane
Rapid cartridge change: Minimised downtimes
Ideally matched to application and compressor: In several pressure stages
Options for expansion: including saturation monitoring (B-SECURUS)
P-filters from BAUER KOMPRESSOREN are high-pressure filter systems that have been proving their worth in application for decades.
This product series is the undisputed classic among BAUER high-pressure treatment systems, offering significant advantages such as quick and straightforward cartridge change, minimum downtimes, and simply cost-effective deployment.
Available in numerous compatible sizes, with cartridges ideally matched to the respective compressor and application, the option of integrating saturation monitoring for moisture (B-SECURUS) and in three pressure stages: 350, 420 and 500 bar.
Depending on the application and filter cartridge, moisture (H2O), oil, carbon monoxide (CO) and particles are absorbed, converted or removed.
All the information you need at your fingertips!
P-filter systems have a check valve to safeguard the minimum pressure in the filter housings. This minimum pressure prevents the maximum flow speed from being exceeded in the filter housing.
Contact time between medium and processing equipment is thus assured right from the outset.
At the same time, pressure fluctuation in the filter housings is reduced, as a result of which the number of permissible load cycles increases significantly, even as far as the fatigue limit.
As they have a safety vent drilled into them, filter housings by BAUER KOMPRESSOREN cannot be operated without filter cartridges inserted.
This prevents contamination of the downstream process due to the unit being operated inadvertently without a filter cartridge.
As the oil and water separator and the P-filter system are entirely separate, the filter system housings are relieved of load cycles almost entirely.
Only the oil and water separator dimensioned for such purposes is exposed to load cycles due to draining condensate and depressurised restarting.
At the same time, this separation makes it possible to integrate the B-KOOK refrigeration dryer upstream of the filter.
The B-SECURUS filter monitoring system monitors the saturation of the filter cartridge with moisture. This makes it possible to optimise the performance of the cartridge at a guaranteed pressure dew-point of -20°C. The display is via a monitoring device integrated into the control system.
Automatic condensate drain
This option should be selected for all installations of P-filter systems in which it is anticipated that condensate will get into the filter system.
Possible causes of condensate getting into the filter system are inadequate separation at the compressor or post-condensation in longer sections of piping.
A range of safety valves for various gases and pressures are available for the P-filter systems.
These filter systems are subject to the requirements of the Pressure Equipment Directive.
All BAUER KOMPRESSOREN treatment systems are also available in gas-tight design.
This means that they support the no-loss treatment of expensive gases.
During the air treatment process, the poisonous carbon monoxide (CO) found in the air is converted into carbon dioxide (CO2). As the proportion of CO is low, the CO2 concentration only increases slightly.
Depending on the air treatment system, CO conversion will take place either in a filter housing together with oil removal or in a separate filter housing.
The "CO conversion" equipment option is only possible in conjunction with the "Oil removal" option.
