What Is a Screw Press?

Self-Cleaning Ring Disc Filter Elements
Fixed and moving stainless steel rings form the filtration gaps and keep them clear continuously — no filter cloth, no clogging.
Explore the RF seriesKey Advantages
Self-Cleaning Design
Moving ring discs continuously clear filtration gaps — no filter cloth, no screen replacement.
Combined Thickening & Dewatering
Process sludge from 0.2% DS upward without separate pre-thickening equipment.
Very Low Energy
Drive power 0.2–5.15 kW. Fraction of centrifuge energy consumption.
Oily & Greasy Sludge
Excels where belt presses and filter presses fail — no cloth blinding.
Low Noise & Vibration
Slow screw rotation means quiet, vibration-free operation.
Modular Scalability
RF-131 to RF-404: single to quad configurations, 6–1,664 kg DS/h.
