JLX-150*1120 Coalescing Filter Cartridge

Product introduction

JLX-150*1120 is a heavy-duty industrial coalescing filter cartridge, custom-engineered for high-efficiency liquid-solid separation in large-flow oil, gas and aqueous fluid systems. Designed with a standard dimension of 150mm in diameter and 1120mm in length, it integrates dual core functions of coalescence (aggregating micro liquid droplets of oil, water and condensate into large, easily separable droplets) and filtration (capturing fine solid particulate impurities). This filter cartridge is built to adapt to high-flow, medium-to-high pressure working conditions of industrial fluid transmission and processing systems, and is fully compatible with mainstream large-scale coalescing filter housings and separators in the market. It effectively removes trace liquid contaminants and solid particles from fluids, protects downstream key equipment such as pumps, meters, turbines and precision valves from erosion, blockage and corrosion, and ensures the purity, stability and safe transmission of fluid media in large-scale industrial production processes, complying with industrial fluid purification and separation industry standards.

Filtration accuracy

JLX-150*1120 features ultra-precise graded coalescence and filtration performance, tailored for the high-purity requirements of large-flow industrial fluid systems. For solid particulate matter in fluids, it achieves a 99.98% filtration efficiency for 3μm fine solid particles, thoroughly intercepting micro impurities that may cause abrasive damage to downstream large-flow equipment. For micro liquid droplets (including oil mist, water mist, hydrocarbon condensate and various industrial liquid aerosols), it realizes high-efficiency coalescence and separation with a liquid removal accuracy of 0.5μm @ 99.99% efficiency, which can aggregate nanoscale micro droplets into large droplets that are quickly captured and discharged by the separator’s liquid collection system. Its filtration and coalescence accuracy remains consistently stable under rated large-flow and pressure conditions, without performance attenuation caused by fluid velocity changes, medium viscosity fluctuations or flow rate variations, meeting the strict ultra-high purity requirements of large-scale industrial fluid processing and transmission.

Filter media

JLX-150*1120 adopts multi-layer composite gradient modified borosilicate glass fiber as the core coalescing and filtration media, compounded with high-strength polyester non-woven fabric through a high-temperature adhesive-free hot-melt bonding process—no chemical adhesives are added, completely avoiding secondary pollution of the filtered fluid caused by adhesive dissolution. The glass fiber media is processed with a special hydrophobic and oleophobic surface treatment, which significantly enhances the coalescence efficiency of liquid droplets and the interception capacity of solid particles, while improving the media’s oil and water repellency and dirt holding capacity. The filter media is protected by an outer high-strength polypropylene (PP) rigid protective mesh with anti-impact and anti-deformation performance, and supported by an inner thickened galvanized steel center tube with high pressure-bearing capacity, which effectively prevents media deformation, rupture or shedding under the impact of large-flow fluids. The end caps are made of high-density epoxy resin with excellent sealing, corrosion resistance and pressure-bearing performance, and the sealing interface uses nitrile butadiene rubber (NBR) gaskets with oil resistance, aging resistance and high airtightness, ensuring zero bypass of unprocessed fluid during the filtration process and guaranteeing the integrity and reliability of the coalescence and separation effect.

Replacement cycle

The recommended replacement cycle of JLX-150*1120 is determined based on the actual contaminant content of the raw fluid, working pressure, flow rate and industrial application environment, with a basic service life of 10–18 months under normal large-flow industrial operating conditions (fluid contaminant content ≤ 40 ppm). For harsh working conditions with high impurity and liquid content, such as upstream oil and gas field mining gathering stations, large-scale crude oil refining systems and industrial wastewater treatment with high solid-liquid mixture, the replacement cycle is recommended to be shortened to 10–14 months to maintain stable high-precision coalescence and filtration performance. For clean fluid media links with low solid particle and liquid content, such as large-flow refined oil transmission pipelines, natural gas trunk pipelines and high-purity industrial fluid circulation systems, the replacement cycle can be appropriately extended to 14–18 months with regular biweekly differential pressure detection and monthly fluid purity sampling tests. For newly commissioned large-flow 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 composite 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.
