  • Trenn bag filter material

    The bag filter material is made of polyester fiber non-woven fabric, melt blown non-woven fabric and other materials by ultrasonic welding, which     improves the production process of the old filter bag in the past, and uses multi-layer filter materials to achieve step by step filtration, so that the air supply of the filter bag is more uniform, the resistance is less, the service life is longer, and the filter made is more beautiful and practical.

  • Trenn Ceiling Cotton And Glass Fiber Filter Felt

    The ceiling cotton is made of high-quality polyester fiber by special process, using viscose agent to penetrate the medium or surface viscose. The glass fiber mat is made of glass fiber, which is in a fluffy state and is suitable for excellent materials in the spraying industry.

  • Trenn Medium Efficiency Filter Material

    The imported polyester fiber filter material is adopted, and the fibers with different internal and external melting points are staggered in a three-dimen- sional structure without orientation, and are made through the process of needle punching, bonding, hot melting, etc. The product has many characteris- tics, such as tight fiber bonding, fracture resistance, non falling off, corrosion resistance, wear resistance and elastic recovery.

    Ultrafine fiber air filter material (PP filter paper)

    A new filter material made of polypropylene by special hot melt method. It reduces the filtering resistance and increases the dust capacity. It is characterized by low resistance, high efficiency, high strength and environmental protection. It is widely used in medium and high efficiency filters, purifiers, oil treatment and water purification facilities.
