The Bühler Technologies AGF-VA-30 Stainless Steel Sample Gas Filter is a premium particulate filtration instrument engineered by Bühler Technologies GmbH (Germany)—a global authority in sample gas conditioning systems. This filter is designed to reliably eliminate fine dust particles, fly ash, and solid mechanical debris from sample gas streams before reaching sensitive analyzers, safeguarding CEMS system integrity.

The filter head of the AGF-VA-30 model is precision-machined from 1.4571 Stainless Steel (316Ti). This material delivers exceptional mechanical strength, high operating pressure/temperature endurance, and superior chemical compatibility against aggressive media including SO2, SO3, NOx, HCl, H2S, CO, and CO2. The filter bowl is available either in transparent borosilicate glass for convenient visual inspection of element contamination or fully in 1.4571 stainless steel for extreme process conditions.

Engineered with an optimized internal flow path, the AGF-VA-30 maintains a very low dead volume (approx. 45 ml to 50 ml), ensuring rapid real-time analyzer response times. The heavy-duty threaded design allows quick, tool-free replacement of 30 mm length filter elements during routine field maintenance.
