Large diameter design: The outer diameter of the filter cartridge is usually 6 inches (about 152mm) or larger, providing space to accommodate more filter media.
No center support skeleton: Many high flow filter cartridges are designed with no center support skeleton, using a structure with one end open, further increasing the effective filtration area.
Efficient folding technology: using horizontal pleating or horizontal folding technology, the filtering area is doubled, which is more than 20 times that of ordinary filter cartridges.
Composite structure: usually composed of three layers: diversion layer, support layer, and filtration layer.
Mainstream materials:
Filter material: mostly polypropylene (PP) or glass fiber (GF). PP has good corrosion resistance, while fiberglass has higher temperature resistance.
End caps and seals: Glass fiber reinforced polypropylene is commonly used for end caps, and sealing ring materials include nitrile rubber (Buna-N), ethylene propylene diene monomer (EPDM), and fluororubber (Viton).
Workflow: There are two main filtering methods: from outside to inside and from inside to outside. Part of the design adopts an inside to outside flow direction, which can intercept pollutants inside the filter element
