Non-woven Filter Media
Basic Info.
Primary Materials: Polyester fiber (PET), Polypropylene fiber (PP), Nylon fiber, etc.
Filtration Grade: Low-efficiency, medium-efficiency, and high-efficiency (based on standards such as EN779, ISO16890, etc.)
Filtration Efficiency: Determined by specific models and specifications, such as MERV (Minimum Efficiency Reporting Value) ratings, DOP (DiOctylPhthalate) test values, etc.
Thickness and Weight: Based on specific application needs, common thicknesses range from 0.5mm to 5mm, and weights vary from tens of grams to several hundred grams per square meter.
Temperature Resistance Range: Depends on the material type, generally suitable for long-term use within a range of -40°C to +120°C.
Flame Retardancy: Some non-woven filter media possess flame retardant properties, complying with relevant fire safety standards.
Non-woven Filter Media Rolls are versatile and highly efficient filtration materials, widely used in various filtration applications including air filtration, water filtration, and industrial filtration. These rolls can also be provided with options of different weights and widths to meet various application requirements as needed.
Material Composition
Particulate filter media are typically made of non-woven fabrics, with their filtration layer mainly consisting of electrostatic cotton or a melt-blown composite fiber framework.
Filtration Efficiency and Applications
The filtration efficiency of Non-woven Filter Media varies depending on its fiber type, structural design, and production process. The common filtration efficiency ranges from low to high efficiency, suitable for various air purification systems such as air conditioning systems, household air purifiers, and air-conditioning filters in transportation. Its high filtration performance enables the removal of harmful substances in the air, including dust, pollen, bacteria, viruses, and others, ensuring indoor air quality.
Physical and Chemical Properties
Non-woven filter media possesses excellent physical and chemical stability, capable of enduring a certain range of temperatures, humidity, and chemical corrosion. Additionally, the interstitial structure among its fibers provides the media with a certain degree of air permeability, which facilitates air circulation and enhances filtration effectiveness.
Manufacturing Process
Fiber Selection and Mixing: Based on application needs and filtration efficiency requirements, appropriate fiber materials are selected and mixed.
Non-woven Fabric Formation: The fiber materials are processed into non-woven fabric form through processes such as carding, web laying, needle punching, and thermal pressing.
Post-treatment: The non-woven fabric undergoes surface treatment, curing, cutting, and other post-treatment processes to enhance its filtration performance and durability.
Quality Inspection: Finished products undergo quality inspection, including filtration efficiency testing, air permeability testing, visual inspection, etc., to ensure that product quality meets standards.
Packaging and Storage: Qualified non-woven filter media are packaged and stored in a dry, well-ventilated environment to prevent moisture and contamination.
