Even though particulate contaminants are removed at the collection point through an effective particulate filter located in the gas sampling probe, there is a risk of secondary contamination when the sample gas line is long or branched. Therefore, additional filters are typically installed at the inlet of the sample gas to the analysis system and before sensitive components of the system. The filter housing must be made of corrosion-resistant and non-absorbent materials, easy to install and maintain. Additionally, various filter elements can be equipped.
The AGF-PV-30 series features a housing made of PVDF and glass, equipped with Bühler's unique quick-lock mechanism. The filter head includes an additional connector for installing a moisture indicator. Depending on the application, different filter materials can be selected.
