Pure Air Generator

The Pure Air Generator PAG 003 is your 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
The PAG 003 pure air generator is the reference source of zero air. The increasing sensitivity of air pollution analyzers, as they are 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. Additionally, it eliminates the need for ultrahigh purity (UHP) zero air cylinders that are a requirement for operating many online process gas analyzers, such as flame ionization analyzers and gas chromatographs. The pure air generator 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.
