The Bühler Technologies ADF-PV-30 Adsorption Sample Gas Filter is an advanced gas purification instrument developed by Bühler Technologies GmbH (Germany)—a global leader in sample gas conditioning systems. This filter is designed to remove unwanted gaseous components and vapors (such as hydrocarbons, oil traces, residual acid gases, or moisture) via physical or chemical adsorption prior to entering sensitive gas analyzers.

The key feature of the ADF-PV-30 model lies in its filter head precision-molded from high-grade PVDF (Polyvinylidene Fluoride), offering superior chemical compatibility against aggressive process gases including SO2, SO3, NOx, HCl, HF, and CO2. The transparent borosilicate glass bowl allows convenient visual monitoring of the adsorbent media's saturation level and color change.

The ADF-PV-30 can be filled with a wide range of commercially available loose adsorbents (such as Activated Carbon, Silica Gel, Puragard, or Molecular Sieve) tailored to the specific gas cleaning requirement. Engineered with minimal internal dead volume, the ADF-PV-30 ensures rapid real-time analyzer response times in continuous process and CEMS monitoring lines.
