Pleated Filter Cartridge

High-efficiency stainless steel pleated filter cartridges with large filtration area, high flow rate, and excellent durability — ideal for liquid and gas filtration.

Stainless Steel Pleated Filter Cartridge Overview

Maidong stainless steel pleated filter cartridges adopt a pleated structure to maximize filtration area within a compact size.
Multiple layers of stainless steel woven mesh or sintered fiber felt provide high dirt-holding capacity and low pressure drop, enabling high flow rates and stable filtration accuracy.

The cartridges are washable and reusable, with excellent corrosion and temperature resistance, making them ideal for continuous operation and frequent backwashing.
They maintain reliable permeability under high differential pressure and deliver long service life in demanding liquid and gas systems.

Typical applications include chemical and petrochemical processes, water treatment, food & beverage, and gas/air purification, where efficiency, durability, and cleanliness are critical.

Key Features & Advantages

Precise Filtration Accuracy

Uniform pleated structure ensures stable pore size and precise particle retention from 1 µm to 200 µm — suitable for fine filtration applications.

Excellent Heat & Corrosion Resistance

Made of stainless steel 304 or 316L mesh, the pleated filter resists high temperature, acid, and alkali corrosion for long-term industrial use.

Washable & Reusable

The pleated design allows repeated cleaning by ultrasonic or chemical methods, extending service life and reducing replacement cost.

High Mechanical Strength

Rigid multi-layer construction maintains shape under pressure and prevents deformation, ensuring consistent filtration performance.

Large Filtration Area

Pleated media increase the effective filtration area several times compared with standard cylindrical filters, improving flow rate and efficiency.

Wide Application Range

Ideal for filtration in chemical, petrochemical, food & beverage, and gas purification systems where reliability and durability are essential.
