Core Definition and Function
Core Function:Captures and separates impurities-such as solid particles and suspended matter-from gases or liquids; enhances fluid cleanliness while protecting downstream industrial equipment from wear and clogging caused by impurities.
Application Scenarios:Spans virtually all industrial sectors, including petroleum refining, chemical and pharmaceutical manufacturing, food and beverage, electronics and semiconductors, power generation, and water treatment.
Common Mainstream Types
Stainless Steel Filter Discs
Material & Process: Made from stainless steel wire mesh or metal powder; manufactured via weaving, sintering, and edge-sealing processes.
Performance Parameters: Diameter of 2.0–500 mm; filtration precision of 0.1–120 microns; resistant to high temperatures and corrosion.
Typical Uses: Gas-liquid separation in industrial distillation and absorption processes; mist droplet removal in automotive engine air filtration systems.
PP String-Wound Filter Cartridges
Material & Process: Polypropylene fibers are wound around a porous polypropylene or stainless steel core with a density gradient, creating a honeycomb structure that is looser on the outside and denser on the inside.
Performance Parameters: Filtration precision of 1–100 microns; withstands a differential pressure of 0.4 MPa; acid/alkali resistance (pH range 2–13).
Typical Uses: High-purity water preparation for biopharmaceuticals; ultrapure water filtration for electronics; industrial oil purification.
Sintered Metal Powder Filter Cartridges
Material & Process:Made from metal powders (e.g., stainless steel, titanium alloy) via cold isostatic pressing and high-temperature vacuum sintering.
Performance Parameters: Filtration precision of 0.5–200 microns; operates at temperatures up to 700°C; supports regeneration via backwashing.
Typical Uses: Petrochemical catalyst recovery; PTA mother liquor filtration; precision separation in aerospace and semiconductor industries.
Hydraulic Oil Filtration Elements
Material & Process: Typically utilizes pleated stainless steel filter media designed to suit hydraulic system operating conditions.
Performance Parameters:Common precision of 15 μm; maximum operating differential pressure of 0.5 MPa; water-resistant and corrosion-resistant. Typical applications: Purification of fluids in industrial hydraulic systems; protection of core hydraulic components such as oil pumps.
