///Needled white NJ series,green white cotton
Product Characteristics
This product is made from imported polyester fiber filter media, featuring a three-dimensional, random-orientation structure created by interlacing fibers with different melting points. It is manufactured through processes such as needling, bonding, and hot-melting. The product offers a variety of characteristics, including tight fiber bonding, high tear resistance, minimal fiber shedding, corrosion resistance, wear resistance, and elastic recovery.
Widely used in bag-type, panel-type, pleated, and spiral-wound filters, this product is suitable for pre-filtration in central air conditioning and centralized ventilation systems, as well as for pre-filtration in large air compressors and clean return air systems.
//Roller filter cotton
Product Introduction
Filter pads or filter rolls can be cut to fit the dimensions of the air outlet and installed directly into it. The air-facing side is typically white but can be customized in colors such as blue, green, or yellow. After treatment, they become washable. With a mesh backing on one side and a paper tube inserted into the roll core, they can be used in automatic roll-type filter units.
Product Features
● Made from high-quality non-woven cotton with high dust-holding capacity and strong adsorption properties
● Meticulously crafted with uniform distribution of filter media
