Separator Cartridges SS436FB-5 Filter

Product introduction

Separator Cartridges SS436FB-5 Filter is a high-performance industrial separation filter cartridge specifically engineered for efficient solid-liquid and liquid-liquid separation in various fluid systems. Designed as a core purification component, it integrates coalescence and filtration functions to effectively remove solid particulate impurities, emulsified water droplets, oil mist, and condensate from fluids such as industrial oils, natural gas, and hydrocarbon fuels. This filter cartridge features a robust structural design that adapts to medium-to-high pressure and variable flow working conditions, and is fully compatible with mainstream separator housings and filtration systems on the market. By delivering high-purity filtered fluids, it effectively protects downstream key equipment including pumps, turbines, precision valves, and flow meters from corrosion, wear, and blockage, ensuring the safe, stable, and efficient operation of the entire fluid transmission and processing system. It complies with international industrial filtration standards, making it a reliable purification solution for a wide range of industrial applications.

Filtration accuracy

The

SS436FB-5 separator cartridge boasts exceptional precision in both solid filtration and liquid separation. For solid particulate matter in fluids, it achieves a filtration efficiency of 99.9% for 3μm solid particles, thoroughly intercepting fine contaminants such as metal shavings, rust, dust, and sludge that may cause abrasive damage to downstream equipment. In terms of liquid separation, it exhibits superior coalescence performance, capable of aggregating and removing 0.3μm micro liquid droplets with an efficiency of 99.99%. This high-precision liquid separation capability reduces the liquid content in the treated fluid to below 50 ppm, meeting the strict purity requirements of critical industrial processes and long-distance fluid transmission. Notably, its filtration and coalescence accuracy remains stable under rated working pressure and flow conditions, without performance attenuation caused by fluid viscosity changes, pressure fluctuations, or temperature variations.

Filter media

The SS436FB-5 separator cartridge adopts hydrophilic modified borosilicate glass fiber as the core filter media, which is manufactured through an advanced adhesive-free hot-melt compounding process. This specialized media design enhances the coalescence efficiency of liquid droplets while strengthening the interception capacity for solid particles, and avoids secondary pollution of the filtered fluid caused by adhesive dissolution. The filter media features a gradient pore structure, with larger pores on the outer layer for preliminary interception of large particles and smaller pores on the inner layer for fine filtration and coalescence, significantly improving dirt-holding capacity while maintaining low pressure drop. To ensure structural stability, the media is supported by an inner 304 stainless steel center tube with high pressure-bearing capacity and wrapped with an outer high-strength polypropylene (PP) protective mesh to resist deformation under fluid impact. The end caps are made of high-density epoxy resin with excellent corrosion resistance and sealing performance, and the sealing interface uses fluororubber (FKM) gaskets that are resistant to high temperature, oil, and aging, ensuring zero bypass of unfiltered fluid and guaranteeing the integrity of the purification process.

Replacement cycle

The recommended replacement cycle of the SS436FB-5 separator cartridge is determined based on the contaminant content of the raw fluid, working pressure, flow rate, and specific application environment. Under normal industrial operating conditions (fluid contaminant content ≤ 40 ppm), the basic service life is 8–16 months. For harsh working conditions with high impurity and liquid content, such as upstream oil and gas field mining systems, large-scale crude oil refining processes, and industrial wastewater treatment systems, the replacement cycle is recommended to be shortened to 8–12 months to maintain stable high-precision separation performance. For clean fluid media links with low solid particle and liquid content, such as refined oil transmission pipelines, natural gas trunk pipelines, and turbine oil circulation systems, the replacement cycle can be appropriately extended to 12–16 months with regular biweekly differential pressure detection and monthly fluid purity sampling tests. For newly commissioned fluid pipeline and filter systems, the first replacement is suggested to be completed within 5 months to remove construction residues such as welding slag, pipe scale, and metal shavings in the pipeline, avoiding permanent damage to the high-precision filter media. The optimal replacement timing can also be judged by the system differential pressure: when the pressure difference across the filter cartridge reaches 0.3 MPa, it must be replaced in a timely manner to prevent excessive system pressure loss, reduced flow rate, and deteriorated purification efficiency caused by media blockage.
