The SPECTRUM Economic Pleated Bag Polypropylene combines cost-effectiveness with high-performance filtration. The primary filter layer is made from steam-processed polypropylene felt, ensuring no fibre release and providing exceptional filtration integrity. With a thickness 10-20 times greater than standard polypropylene, the EPBP delivers an ultra-high flow rate with a low pressure drop, making it ideal for prefiltration applications. Its excellent porous structure significantly extends service life to up to 4 times that of traditional filter bags, ensuring long-lasting, reliable performance.
