AALBF-5A Screw Cap Type PPH Polypropylene Homopolymer Bag Filter Housing for Industrial Filtration

The AALBF-5A PPH Bag Filter Housing is a high-performance liquid filtration solution designed for applications requiring excellent chemical resistance, secure sealing, and easy maintenance.

Manufactured from imported Polypropylene Homopolymer (PPH) using one-piece injection molding, the AALBF-5A features a seamless, weld-free structure that eliminates leakage risks and ensures long-term mechanical strength. Its screw-cap type design allows for fast, tool-free operation, making it ideal for frequent filter bag replacement and routine maintenance.

Designed as a bag-type filter housing, the AALBF-5A is compatible with standard Size #5 filter bags (φ150 × 510 mm) and can also be modified into a cartridge filter housing capable of holding three 20-inch filter cartridges, offering excellent flexibility for different filtration processes.

Fully compliant with international standards, the AALBF-5A is compatible with globally recognized filter bag brands such as EATON, FSI, and PALL, as well as domestic standard bags, ensuring easy sourcing and global applicability.

With a maximum operating pressure of 8 bar (116 psi) and temperature resistance up to 90°C (194°F), the AALBF-5A delivers stable and reliable filtration performance across demanding industrial environments, including chemical processing, pharmaceuticals, electronics, wastewater treatment, and desalination.
