Advanced filtering systems for low- to high-flow volumes

Fives’ gas filtering systems are designed for optimum productivity, with a distinct solution for either low-pressure or high-pressure filtering:

TGT® Filter

The TGT® Filter is dedicated to high flow volume gas treatment. Using a long bag, it has its own low-pressure pulse cleaning technology to capture particulates in process gas. Its key features include:

  • Fully automated operation
  • Reduced cleaning frequency
  • Optimized compressed air consumption
  • Easy maintenance through compartment isolation
  • Stable pressure drop

Sonair™ Filter

The Sonair™ Filter system uses high-pressure pulse cleaning technology to capture particulates in process gas and is dedicated to low-flow volume gas treatment. Its key features include:

  • Reliable and proven baghouse technology
  • High-pressure pulse jet cleaning

Efficient, reliable and environmentally sound

Both bag filters offer a host of benefits, including exceptional energy efficiency, and simple cleaning and maintenance.

TGT® Filter:

  • Compliant with the most stringent environmental regulations
  • Highly efficient, thanks to optimized gas and dust distribution within the entire filter body, minimized can velocities and limited re-entrainment of dust particulates. The filter has been subject to a complete in-house computational fluid dynamics (CFD) analysis
  • Increased bag life and filtering efficiency thanks to the TGT® low-pressure pulse jet cleaning system, using an Integral Action Piston (IAP™) valve
  • Compact footprint thanks to its long bag technology: filters measure 8+ m (26+ ft)
  • Process stability thanks to an ''online'' cleaning sequence using a proportional–integral–derivative (PID) control loop to provide a constant pressure drop
  • Modular design available for easy installation

Sonair™ filter:

  • Reliable and proven baghouse technology
  • Easy offline maintenance
  • Provides rapid and powerful opening-efficient cleaning thanks to its diaphragm valve

A wide range of applications across the cement plant

Fives’ process filters efficiently clean gas emissions in various cement plant applications.

TGT® filter:

  • Main kiln / raw mill
  • Clinker cooler dedusting
  • Finish mill

Sonair™ filter:

  • Material collection downstream of the classifier in a finish mill
  • Clinker cooler dedusting
