Product overview
GeoFilter GFB2 with rotary valve is a self-cleaning cartridge filter designed for efficient extraction and filtration of dust from demanding industrial processes such as welding, grinding, cutting and powder coating. The unit is based on the proven GFB2 platform and provides continuous dust discharge via an integrated rotary valve and big bag solution. Automatic compressed-air cleaning ensures stable operation, long filter life and reduced maintenance.

Key features

• Self-cleaning cartridge filter with high filtration performance
• Integrated rotary valve and big bag for safe, continuous dust handling
• Automatic compressed-air cleaning (pulse cleaning)
• Filtration efficiency up to 99.97%
• Robust hot-dip galvanised steel construction
• Ready for fast installation, supplied ready for connection to power and compressed air
• Scalable design: multiple units can be connected in parallel
• User-friendly control unit with digital settings for pulse intervals and after-run cycles; optional differential pressure control for automatic cleaning optimisation

Application notes
Designed for demanding industrial environments. Separated dust is discharged continuously through the integrated rotary valve into a big bag, reducing dust exposure, improving hygiene and operator ergonomics and minimising downtime. Cartridge filters are available in different media types (e.g. FT/11) for various applications.
