Custom 316L Stainless Steel Pleated Oil Filter Cartridge – 480°C Max Temperature, 5 Bar Differential Pressure

Customized PHSC 316L Stainless Steel  Pleated Oil  Filter Cartridge

Engineered for the toughest industrial filtration environments where extreme temperatures, aggressive chemicals, and high-pressure conditions challenge conventional filters.

The PHSC series pleated filter cartridges are constructed entirely from 316L stainless steel, featuring high-performance sintered fiber felt media. The precision pleated design provides a large filtration area within a compact structure, ensuring efficient particle removal and stable flow performance.

Its graded pore structure, with coarser upstream and finer downstream layers, enhances dirt-holding capacity while minimizing pressure drop. The robust stainless steel construction offers excellent mechanical strength, corrosion resistance, and long service life. The elements are cleanable and reusable under suitable operating conditions, helping reduce maintenance and replacement costs.

Typical applications include hydraulic oil filtration, lubricating oil systems, industrial oil purification, fuel filtration, and filtration of process fluids in petrochemical and chemical processing industries. The PHSC series is particularly suitable for demanding applications requiring reliable filtration, high dirt-holding capacity, and reusable filter elements.

Key Features:

• All 316L Stainless Steel Construction – Fully welded design with sintered fiber felt media for excellent structural integrity and minimal risk of media shedding.
• High-Temperature Resistance – Maximum operating temperature up to 480°C under specified conditions, suitable for hot oil and high-temperature process fluid filtration.
• Excellent Corrosion Resistance – Resistant to a wide range of industrial oils, solvents, and compatible chemical fluids.
• High Dirt-Holding Capacity – Graded pore structure provides effective depth filtration and extended service intervals.
• Large Filtration Area – Precision pleated design supports high flow rates with low initial pressure drop.
• Cleanable & Reusable – Supports suitable cleaning methods for extended service life and reduced replacement costs.
• Differential Pressure Rating – Maximum allowable differential pressure of 5.0 bar under specified operating conditions.
