Sintered metal mesh witch hat filter elements

Stainless Steel Metal Mesh Witch Hat Filter Elements are precision-engineered conical filters designed to maximize filtration efficiency and flow rates in demanding industrial processes. Crafted from high-grade 304/316 stainless steel, these filters feature a unique conical (witch hat) shape that provides a larger surface area for enhanced debris retention, reduced pressure drop, and easy cleaning. Ideal for viscous fluids, slurries, or high-particulate media, they deliver unmatched durability and performance in harsh environments.

Our witch hat filters are produced using cutting-edge technology for consistent quality:

• Material Selection: Premium stainless steel wires or perforated sheets sourced from certified suppliers.
• Mesh Weaving/Perforation: CNC looms or laser punching create uniform apertures for precise filtration.
• Conical Forming: Hydraulic press or spiral welding shapes the mesh into a seamless conical structure.
• Edge Reinforcement: TIG welding or flanging ensures leak-proof edges and mechanical strength.
• Surface Treatment: Passivation, electro-polishing, or heat treatment for enhanced corrosion resistance.
• Quality Control: Rigorous testing includes pressure resistance, mesh accuracy, and material composition checks (ISO 9001 certified).

Superior Material Quality

• Grades: 304, 316, or 316L stainless steel for exceptional resistance to corrosion, acids, and high temperatures (up to 800°C / 1472°F).
• Rigid Structure: Reinforced mesh layers and welded seams ensure stability under high-pressure conditions (up to 30 MPa).

Optimized Conical Design

• High Flow Capacity: Conical shape increases filtration surface area, minimizing clogging and maximizing throughput.
• Mesh Options: 50–400 mesh sizes for precise particle retention (1–500 microns).
• Custom Dimensions: Tailored cone angles, heights (50–500mm), and base diameters (20–300mm) to fit specific equipment.

Reusable & Low Maintenance

• Easy backwashing or ultrasonic cleaning extends service life and reduces operational costs

Stainless steel witch hat filter elements are essential in:

• Chemical & Petrochemical: Filtering aggressive acids, polymer melts, and catalyst slurries.
• Food & Beverage: Clarifying syrups, oils, and dairy products (FDA-compliant finishes).
• Pharmaceutical: Sterilizing APIs, solvents, and fermentation broths (GMP standards).
• Water Treatment: Removing sediments and algae in high-flow filtration systems.
• Mining & Energy: Screening abrasive slurries and hydraulic fluids.
