The crumpled liquid filter bag is manufactured using an adhesive-free thermal welding process. It features a multi-layer depth filtration structure consisting of a polypropylene pre-filtration layer, multiple crumpled ultrafine-fiber pre-filtration layers, multiple ultrafine-fiber final filtration layers, and a polypropylene anti-shedding outer layer.
This multi-layer crumpled design provides greater dirt-holding capacity while significantly increasing the flow rate and reducing pressure drop. The filter bag is made from hygienic-grade filtration materials that comply with FDA requirements and contains no impurities or lubricants. It combines high-precision filtration with rapid adsorption of various oils and greases.
Crumpled liquid filter bags are widely used in the pharmaceutical, food and beverage, fine chemical, and electronics industries, as well as in methanol production, biofuel production, water treatment, and other industrial liquid filtration applications.
Description
Key Features
- The crumpled construction increases the effective filtration area of a standard Size #2 filter bag to up to 1.2 m², providing higher flow capacity and greater dirt-holding capacity.
- The multi-layer, graded-density depth filtration structure delivers high filtration efficiency and an extended service life.
- Low differential pressure ensures stable filtration performance and reduces filter replacement frequency.
- Made from hygienic-grade materials, offering high filtration accuracy and excellent oil adsorption performance.
- Broad chemical compatibility makes it suitable for a wide range of liquid filtration applications.
