The HQPK1 series high-flow filter cartridges are developed to meet market demands. They adopt deep and fine membrane materials and a multi-layer gradient aperture filtration structure to achieve higher dirt-holding capacity and dust capacity. With a single opening and an outside-to-inside flow direction for filtered fluids, the 6.7-inch large diameter effectively increases the filtration area and dirt-holding capacity, reduces the number of filter cartridges used, and lowers costs. Suitable models can be selected according to different filtration requirements.
