Pure Air Generator

The Pure Air Generator PAG 003 is your reference source of efficient and reliable zero air. It eliminates the need for ultrahigh-purity zero air cylinders. The PAG 003 is specifically designed for CLD analyzers measuring sub ppb levels. Other trace gas analyzers benefit as well.

Pure and reliable
Increasing sensitivity of air pollution analyzers, as required by laws and regulations, demands pure air in sufficient quantity and at constant pressure. For zero-point verification and calibration of gas analyzers, as well as the dilution of calibration gases and for GPT, a source of very pure compressed air is needed. The PAG 003 eliminates the need for ultrahigh purity (UHP) zero air cylinders that are needed for operating many process gas analyzers, such as flame ionization analyzers and gas chromatographs. The PAG 003 delivers pure air, free from water vapor, particles, sulfur dioxide (SO2), oxides of nitrogen (NOX), ozone (O3), carbon monoxide (CO) and hydrocarbons (HC).

The PAG 003 is designed for continuous operation. Maintenance requirements are minimal and easy to perform. The installed particle filters and water traps guarantee seamless operation.
