YZL216 Continuous Rotary Drum Filter for Pigment & Dye Slurry Pressure Vacuum Filtration
The YZL216 Rotary Pressure Vacuum Drum Filter is a next-generation solid-liquid separation system that integrates filtration, cake washing, drying, automatic discharge, and self-cleaning into one fully enclosed continuous process. Unlike traditional GXG-type Nutsche filters that rely on mechanical agitators, the YZL series is engineered with a rotary drum mechanism — no internal agitator, no mechanical stirring, just pure rotating drum filtration.

Key Features
- Agitator-Free Rotary Drum Design — Eliminates mechanical wear from agitator blades; ideal for solvent-based, volatile, and flammable materials
- Continuous Multi-Stage Processing — Filtration → washing → drying → discharge → media cleaning, all in one uninterrupted cycle
- Pressure & Vacuum Dual Operation — Flexibly switch between pressurized and vacuum modes based on material viscosity and filtration requirements
- Stepless Variable Speed Control — Adjust drum rotation speed to optimize cake thickness (2-20 mm) for different slurry characteristics
- Fully Enclosed Explosion-Proof Construction — Zero solvent vapor emissions, compliant with ATEX standards for hazardous environments
- CIP Self-Cleaning System — Integrated automatic cleaning of filtration media between batches without disassembly
- Low Operating Cost — No agitator motor power consumption, reduced maintenance intervals, long service life

Target Applications
- Pharmaceutical: API crystallization filtration, solvent-based intermediate washing and drying
- Fine Chemicals: Pigment filtration with organic solvent recovery, dye intermediate processing
- Petrochemical: Catalyst separation and washing under pressure
- Food & Beverage: Edible oil filtration, sugar syrup clarification
- Environmental: Industrial sludge dewatering, hazardous waste treatment
Why Choose YZL Over GXG Nutsche?
If you handle volatile solvents, flammable materials, or toxic slurries, the agitator in a traditional GXG Nutsche filter introduces unnecessary risk — mechanical seal leakage, spark hazards, and batch inconsistency. The YZL rotary drum design eliminates the agitator entirely, delivering safer, faster, and more consistent solid-liquid separation with lower total ownership cost.
