Lined Filter
- Excellent Corrosion Resistance: All flow surfaces lined with fluorine, capable of resisting almost all chemical media erosion
- High Filtration Accuracy: High-precision filter mesh effectively removes solid particle impurities
- Good Flow Performance: Reasonable design with minimal pressure loss
- Easy Maintenance: Removable filter mesh for easy cleaning and maintenance
- Long Service Life: Fluoroplastic lining is corrosion-resistant with long service life
- Wide Application Range: Suitable for various corrosive media
Lined Filter is a special filtration device based on the traditional filter, with a layer of fluoroplastic (such as PTFE, FEP, PFA, etc.) lining on the inner surface of flow-contacting components such as the filter housing. This filter is mainly used to remove solid particle impurities from corrosive media, protecting downstream equipment from particle damage. Lined Filters have excellent corrosion resistance, capable of effectively resisting the erosion of corrosive media such as strong acids, strong alkalis, and organic solvents, while maintaining the advantages of filters such as high filtration accuracy and good flow performance. Lined Filters are widely used in corrosive medium pipeline systems in industries such as chemical, petrochemical, pharmaceutical, pesticide, and dye.
