The Bühler Technologies AGF-T-30 PTFE Sample Gas Filter is an advanced particulate filtration solution engineered for applications requiring complete chemical inertness in industrial gas analysis. Manufactured by Bühler Technologies GmbH (Germany)—a global authority in sample gas conditioning components—the AGF-T-30 plays a vital role in protecting sensitive analyzer sensors within CEMS environments.

The outstanding advantage of the AGF-T-30 model lies in its filter head, constructed entirely from 100% pure PTFE (Polytetrafluoroethylene / Teflon). This material is completely inert and non-reactive, ensuring that sample gas composition remains unaltered even when handling highly aggressive media containing SO3, Cl2, HF, HCl, HNO3, or organic solvents. The clear borosilicate glass bowl allows effortless visual inspection of filter element contamination without opening the assembly.

Engineered with an optimized internal gas path, the AGF-T-30 keeps dead volume to an absolute minimum (approx. 45 ml to 50 ml), guaranteeing fast real-time system response. The heavy-duty hand-threaded retaining ring allows quick, tool-free filter element replacement during routine field maintenance.
