BAUER KOMPRESSOREN high-pressure air and gas purification systems backed by over 65 years of air-purification experience. Depending on the cartridge chosen, the P-filter / TRIPLEX cartridge systems adsorb residual moisture, oil vapor, traces of hydrocarbons, and carbon monoxide, not only meeting but exceeding all DIN EN 12021 requirements for breathing air (as well as CGA G-7.1, STANAG 1079, BS 4001, and other standards). Industrial P 80/100/120/140 systems operate in several pressure stages with rapid cartridge change. SECCANT regeneration dryers cover the 50–420 bar range, while the B-SECURUS system monitors cartridge saturation and warns of end of life. The cartridges contain a molecular sieve, activated carbon, and a CO catalyst that converts carbon monoxide to carbon dioxide.
