  • Application Areas

Suitable for various applications in air conditioning systems, including pre-filtration for central air conditioning and centralized ventilation systems, pre-filtration for large air compressors, clean return air systems, and pre-filtration for local high-efficiency filtration units. Examples include air conditioning systems in commercial buildings, warehouses, schools, laboratories, and similar facilities. The filter media itself contains no silicone, making it particularly suitable for use in spray painting workshops. It provides biologically inert filtration.

  • Product Description

Primarily blocks dust particles larger than 5μm, constructed from a composite of polypropylene, synthetic fibers, and spunbonded fabric, assembled with various metal frames. Moreover, this bag filter employs a robust, leak-proof bag design to capture dust overflow. The bag features triple-sided sealing, with the airflow channel sewn horizontally inside the bag. A thermoplastic sealant is applied to bond the seams through heat-melting and pressing, ensuring uniformity throughout the entire airflow.
