The Bühler GAS 222.30 Ex1 Explosion-Proof Heated Gas Sampling Probe is a specialized industrial sample extraction unit engineered by Bühler Technologies GmbH (Germany). Compliant with stringent international explosion protection standards (ATEX / IECEx Zone 1, Zone 21), this probe is designed specifically for extreme operating conditions characterized by heavy dust loads and elevated temperatures in hazardous environments such as petroleum refineries, petrochemical plants, gas processing facilities, industrial incinerators, and explosion-proof Continuous Emission Monitoring Systems (CEMS).

A key highlight of the GAS 222.30 Ex1 model is its Ex-certified, tool-free quick-release filter cover mechanism (Easy-Lock System). This design enables maintenance technicians to inspect and replace the internal filter element (Ceramic or SS316L stainless steel) effortlessly without requiring additional tools. This significantly reduces maintenance downtime and minimizes the time technicians spend performing service tasks in hazardous Ex zones.

Equipped with an integrated Ex-proof self-regulating electric heating element, the probe head maintains a constant operating temperature of up to 200°C (T4 rating). Continuous heating prevents moisture condensation, acid dew point drop, and fine dust adhesion on the filter element, preserving sample gas integrity before delivery to downstream analyzers. Combined with an integrated pneumatic blowback connection for automated filter purging, the Bühler GAS 222.30 Ex1 guarantees reliable, uninterrupted 24/7 continuous extraction performance.
