Industrial Air

Purification and auxilliary equipment

represent BAUER’s comprehensive air and gas treatment portfolio designed for operating pressures up to 6,000 PSIG (420 bar). Engineered to eliminate moisture, oil vapor, carbon monoxide, particulates, and odor from high-pressure compressed air, nitrogen, helium, and noble gases, these high-pressure purification systems ensure total compliance with ISO 8573-1, CGA Grade D/E, and NFPA 1989 standards.

Twin-tower heatless desiccant drying system engineered for continuous 24/7 operation at high pressure, automatically regenerating desiccant beds without cartridge replacements.

Integrated sensor technology that continuously tracks cartridge moisture saturation and provides visual pre-warnings before automatically shutting down the compressor upon exhaustion.

Cools compressed air before entering purification cartridges, condensing moisture early and increasing cartridge life up to 11 times for significant operational savings.

Heavy-wall anodized aluminum and stainless steel vessel construction certified for extreme operating pressures and severe industrial environments.
