SS Series Separator Filter Cartridges

Product introduction

SS Series separator filter cartridges are high-performance, multi-purpose industrial separation elements designed for efficient solid-liquid and liquid-liquid separation in a wide range of industrial fluid systems. Engineered with a unified structural platform and modular design, the series covers multiple precision and size variants to meet diverse purification demands, focusing on removing solid particulates, free water, emulsified water, oil mist, and condensate from hydrocarbon fuels, lubricating oils, hydraulic oils, natural gas, and process fluids. These cartridges integrate coalescence, separation, and fine filtration functions, delivering stable performance under medium to high pressure, variable flow, and fluctuating temperature conditions. With standardized interfaces and broad compatibility with mainstream filter housings and separation systems, SS Series cartridges protect critical downstream equipment including compressors, turbines, pumps, meters, and control valves from abrasion, corrosion, blockage, and performance degradation, ensuring fluid purity, system safety, and operational efficiency across the industrial chain.

 

Filtration accuracy

SS Series separator cartridges offer graded precision options to match different application requirements, with consistent high separation efficiency across the range. For solid particle removal, standard ratings include 10μm, 3μm, and 1μm, with filtration efficiency reaching up to 99.9% for rated particle sizes, effectively capturing rust, sludge, metal shavings, pipeline scale, and colloidal impurities. In liquid separation, the series excels in coalescing and removing micro water droplets and oil mist, with a liquid separation precision ranging from 0.5μm down to 0.1μm and separation efficiency as high as 99.99%. High-end models can reduce residual moisture in treated fluids to below 50 ppm, meeting strict purity standards for natural gas transmission, turbine lubrication, precision manufacturing, and petrochemical processes. Filtration and separation performance remains stable under rated operating conditions, with no significant efficiency loss due to changes in flow rate, pressure, fluid viscosity, or ambient temperature.

Filter media

The entire SS Series employs high-performance composite filter media tailored for separation efficiency, durability, and chemical compatibility. Core variants use hydrophilic-modified borosilicate glass fiber media produced via an adhesive-free hot-melt lamination process, featuring a gradient pore structure that enhances coalescence efficiency, dirt-holding capacity, and low pressure drop while eliminating secondary pollution from adhesive leaching. General-purpose models use high-strength gradient polyester non-woven media, offering robust structure, large dirt capacity, and cost-effectiveness for pre-filtration and primary separation. High-temperature and corrosive environment variants use PTFE-coated glass fiber or sintered metal fiber media for enhanced resistance. All cartridges are reinforced with an internal metal support tube (galvanized steel or 304/316L stainless steel) and an external protective mesh to prevent deformation under fluid impact. End caps are constructed from high-strength epoxy resin or corrosion-resistant metal, paired with NBR or FKM gaskets to ensure zero bypass and reliable sealing.、

 

Replacement cycle

The replacement cycle for SS Series separator cartridges varies by model, fluid contamination level, and operating environment, with typical service lives under normal conditions ranging from 8 to 24 months. For standard models in moderately contaminated systems (impurity content ≤ 50 ppm, water content ≤ 500 ppm), the recommended replacement period is 12–18 months. In harsh conditions such as upstream oil/gas fields, heavy-duty hydraulic systems, and high-moisture fuel systems, the cycle is shortened to 8–12 months to maintain optimal performance. In clean applications such as refined fluid transmission, gas pipeline boosting stations, and precision equipment lubrication systems, the cycle can be extended to 18–24 months with regular differential pressure monitoring and fluid quality testing. For newly commissioned systems, the first replacement is suggested within 4–6 months to remove construction residues. The definitive replacement trigger is a differential pressure across the cartridge of 0.25–0.35 MPa, indicating media blockage and reduced separation efficiency.
