FAQ's
Frequently Asked Questions
Selection Criteria for ATEX bag filter?
Start with your dust characteristics (combustible risk, particle size, loading), required air volume, temperature (up to 260 °C), and pressure (up to 33 bar). Then consider site constraints (horizontal/vertical layout), automation (pulse-jet cleaning), and required ATEX conformity for explosive atmospheres.
TNBi states that ATEX compliance can be offered, which means protection measures (e.g., explosion venting/isolation, antistatic design) are selected per risk assessment under the ATEX framework.
What are the benefits of an ATEX Bag Filter compared to other types of bag filters?
For areas handling combustible dust, an ATEX-compliant unit provides risk-appropriate explosion protection and documented conformity, something a other types of bag filter units don’t guarantee.
With TNBi, you also get pulse-jet automatic cleaning, compact design with high filter-area utilization, and the ability to handle large gas flows while operating up to 260 °C and 33 bar. This combination improves safety, uptime, and compliance in hazardous zones.
