Suitable Solutions for Every Application

Non-metallic mineral processing companies face moisture, fines loss, and equipment wear. Our tailored filtration solutions improve product quality, boost throughput, and reduce downtime, to ensure consistent performance and lower the total cost of ownership.

Concrete

Operations face abrasive materials, variable particle sizes, and high moisture demands, while frequent filter wear and process interruptions reduce productivity and increase maintenance.

Our robust filtration solutions withstand harsh environments and ensure reliable performance across all equipment. By reducing moisture, extending filter life, and improving throughput, Sefar filters maintain consistent output while lowering the total cost of ownership.

  • Cement: Our durable filter bags and pleated elements for baghouses ensure reliable dust capture.
  • Gravel and sand: Sefar cloths for filter presses support high flow and reduce wear in the abrasive conditions of gravel and sand applications.
  • Talcum and chalk: Sefar’s filter cloth designs and fabrics are chosen to provide high efficiency filtration and good cake release.
