Secondary filtration after TNBi Cyclone reduces choking

Case Studies

Proven in the Field

Bag Filter Retrofit Boosts Mill Efficiency by 50%
Challenge: A A Polymer manufacturing company faced frequent bag choking, high DP, and ID fan noise leading to 6-hour stoppages every 3 days. Their system was working only at 35% of its designed capacity.
TNBi Solution: We replaced their existing bag filter with a custom-designed unit optimised for pressure, airflow, and filter area. TNBi’s bag filter was seamlessly integrated with the existing cyclone and ID fan of the mill.
Result
  • Capacity increased to 75% (50% boost)
  • No choking for over a month
  • Maintenance time was reduced by 85%
  • Stable fan load and quieter operation

FAQ's

Frequently Asked Questions

How often should I replace the filter media?
Replacement intervals depend on dust load, operating hours, and cleaning system. With pulse-jet cleaning, the media can last several months.
Vent Filter removes dust particles from air released through vents during material transfer or pneumatic conveying, ensuring cleaner exhaust and environmental compliance.
Yes. Its compact design allows easy integration into new or existing setups.
