Hydraulic Filter-Double Slide Plate Continuous Screen Changer Melt Filtration System
**Hydraulic Filter - Double Slide Plate Continuous Screen Changer Melt Filtration System**
This **GM-DSP series double plate type continuous screen changer** is designed for **plastic extrusion machines**, offering a highly efficient and reliable solution for **polymer melt filtration**. Compared to the **GM-SSP single plate hydraulic screen changer**, the GM-DSP series provides a **continuous operation** feature, ensuring no downtime during the screening process.
### Key Features:
- **Double Slide Plate Design**: Two slide plates replace one, allowing for **two separate screen cavities** instead of one.
- **Quick Screen Change**: Maintains the same fast screen replacement as the single plate version.
- **High Pressure Resistance**: Operates effectively under **45 MPa (450 bars)** without compromising performance.
- **Customizable**: Available in various sizes and configurations to match different extrusion systems.
- **Air Venting System**: Helps remove gas trapped in the polymer melt, improving product quality.
