Cobetter Duredunty Filter Cartridges are made of a unique double-layer PES membrane and are designed as final filter for dye-based inkjet inks filtration. The double-layer membrane provides excellent filtration efficiency and can eliminate most of the difficulties encountered by inadequate removal efficiency.
Features
- Double-layer membrane provides excellent filtration efficiency and highest assurance of ink quality.
- Built in Asymmetric prefilter layerfor longer life time and excellent gel removal. Recommended for ecosolvent ink gel removal.
- Hydrophilic membrane with low initial differential pressure.
- Each element is individually integrity tested to ensure filter quality. The filter’s bubble point ≥5bar with 0.1+0.03 removal ratings.
- Provides broad chemical compatibility (pH1-14); excellent compatibility with dye-based ink chemistries.
Applications
- Filtration for Dye-Based Ink Jet Inks
