BAUER P-filter systems (P stands for the German word Patrone, cartridge in English) can be relied upon to remove all hazardous substances, enabling you to breathe in clean breathing air.
Depending on the cartridge selected, BAUER P-filter systems are able to adsorb residual moisture,oil vapour, traces of hydrocarbon gases and carbon monoxide. With BAUER P-filter systems, all of the requirements of DIN EN 12021 for breathing air are not only met but even exceeded.
The compressed air is fed out of the compressor block and into the final separator, where the condensate (a mixture of oil and water droplets) is mechanically separated and discharged safely through the condensate drain valve.
The air cleaned upstream then flows through the P-filter system, which adsorbs the remaining water in the form of steam, removing hazardous contents from your breathing air at the same time.
¹ If the units are maintained and installed correctly as described in the user manual and subject to the BAUER AERO-GUARD being used if CO2 concentration in the intake air exceeds prescribed standard values.

The technology of each and every P-filter cartridge is perfectly matched to the corresponding BAUER P-filter system. Original BAUER filter cartridges with premium quality filter materials ensure that oil, moisture, oil vapour, hydrocarbon compounds, coarse impurities or minute particles are effectively removed from the compressed air.
The ideal P-filter cartridge composition for each application is formulated, optimised and reliably tested in the BAUER quality testing centre.
Original BAUER filter cartridges benefit from a perfectly harmonised ratio of activated carbon to molecular sieve. Compliance with the strict limit values specified in the applicable standards for breathing air and air used in medical applications (e.g. according to DIN EN 12021 and the European Pharmacopoeia) is thereby assured. In many cases, using a BAUER P-filter system will even lead to the requirements of the corresponding standards being exceeded¹.

The production conditions at BAUER and the strict BAUER quality management system ensure that every P filter cartridge is filled hygienically and without saturation before being vacuum-packed, sealed and checked for leaks.
The pressure retention valve keeps the filter housing constantly under pressure. Pressure fluctuations inherent in the process are noticeably reduced, significantly increasing the service life of the filter housing and operational safety.
The filter housings are subject to seamless checks and documentation. BAUER KOMPRESSOREN is a certified manufacturer in accordance with the EU Pressure Equipment Directive.
The housings of the BAUER KOMPRESSOREN P-filter system (filter housings) are made exclusively from special aluminium alloys or chemically nickel-plated high-strength steel. This is the reason why BAUER filter housings can be relied upon to withstand ultra-high pressures of up to 500 bar and thousands of load cycles.
Filter cartridges filled by customers or cartridges from third-party manufacturers are hazardous to health due to their poor filter performance: downstream systems can suffer corrosion, ice up and become contaminated.
