Drum filtration unit FF series

for coolantoilself-cleaning

Overview
The ROTOFILTER filtration unit treats contaminated oils and coolant lubricants produced by machining operations with swarf removal. Filtration is performed by a self-cleaning drum filter using FAMA technology. A centrifugal pump feeds contaminated coolant from the machine tool into the ROTOFILTER where tailored filter elements separate contaminants. The filtered coolant is continuously discharged to maintain a constant supply to the machine tool. Filter cleaning is automatic and sludge is removed via a dredging evacuation system.

Key product features

• Self-cleaning drum filter (FAMA technology)
• Continuous filtered coolant outflow for stable supply to machine tools
• No disposable filter media required
• Automatic sludge evacuation (dredging system)
• Compact footprint
• Designed to protect mechanical components, cutting tools and pumps
