LEFILTER provides high-precision, drop-in replacement coalescing filter element for the original FACET CA11-8. Fully interchangeable with standard FACET filter housings, this CA11-8 coalescer cartridge adopts multi-layer graded glass fiber media to achieve efficient solid particle interception and micro water droplet coalescence. It perfectly matches the original size, installation interface, sealing performance and separation efficiency of the OEM FACET CA11-8 filter. Designed for high-flow fuel and natural gas purification working conditions, our alternative filter delivers stable long-term operation, effectively reduces equipment maintenance frequency, and helps industrial users cut procurement and operating costs without any equipment modification.
In petrochemical, fuel storage and natural gas treatment systems, tiny water droplets, oil mist and fine solid impurities are the main causes of instrument wear, pipeline corrosion, fuel quality degradation and system liquid hammer. As a classic high-flow coalescing filter model of FACET, CA11-8 is widely used in medium and large flow fluid separation processes. However, the original FACET CA11-8 filter has the disadvantages of long delivery cycle and high OEM price, which increases the operating cost of long-term industrial consumption. LEFILTER independently develops and produces interchangeable FACET CA11-8 coalescing filter elements, which are strictly produced according to original industrial standards. With optimized medium density and structural design, our filters adapt to complex working conditions such as flow fluctuation and medium temperature change, maintaining efficient and stable coalescing and filtration performance all the time.
Working Principle of FACET CA11-8 Coalescing Filter Element
Different from ordinary single-layer particulate filters, the CA11-8 coalescing filter adopts gradient composite medium structure, realizing dual functions of impurity filtration and liquid droplet coalescence. When polluted gas or liquid fuel passes through the filter element, the outer coarse filter layer first intercepts large solid particles, dirt and impurities to protect the inner fine coalescing layer and prevent early blockage of the precision medium layer.
After preliminary filtration, the clean fluid contacts the inner high-hydrophilic glass fiber medium. A large number of suspended micro water droplets and oil mist adhere to the fiber surface. Under the action of fluid shear force and intermolecular tension, tiny dispersed droplets continuously collide, aggregate and grow into large-diameter droplets that cannot be suspended in the fluid. Relying on gravity, the large droplets settle down to the bottom liquid collection area of the filter vessel and are discharged separately. The purified fluid passes through the filter element smoothly, finally realizing high-efficiency removal of solid impurities and free water, and completing precise fluid purification.
LEFILTER’s upgraded CA11-8 replacement filter optimizes the internal fiber layup and density distribution compared with ordinary generic products. It effectively avoids fluid channeling caused by uneven medium compression, ensures uniform fluid distribution in all areas of the filter element, greatly improves dirt holding capacity and coalescing stability, and extends the service cycle under high-flow working conditions.
Product Structure & Material Advantages of LEFILTER CA11-8 Replacement Filter
We strictly follow the original FACET CA11-8 structural standards and upgrade raw materials and production processes to ensure that the interchangeability, durability and filtration performance of the alternative filter fully reach the OEM level, with more stable cost performance.
1. High-efficiency Gradient Borosilicate Glass Fiber Medium
The main filter medium adopts imported high-hydrophilic borosilicate glass fiber, with multi-layer progressive density design. The material has excellent chemical stability, strong adaptability to hydrocarbon media such as diesel, aviation kerosene, gasoline and natural gas, and will not be corroded or deformed by media erosion for a long time. It can efficiently capture 3μm micro-droplets and fine particles, with a coalescence removal efficiency of up to 99.6%. The gradient structure makes the dirt interception more layered, effectively improving the overall dirt holding capacity and avoiding rapid blockage under high-flow operation.
2. Corrosion-resistant Reinforced Polypropylene End Caps
Consistent with the original FACET CA11-8 size and installation standard, the upper and lower end caps are made of high-strength modified polypropylene material, with integrated metal stud bolt connection structure. The installation size, thread specification and sealing interface are 100% compatible with the original filter housing. Users can replace the filter directly without drilling, cutting or modifying equipment pipelines. The end cap material has strong temperature resistance and anti-aging performance, effectively avoiding cracking and liquid leakage caused by temperature cycling and pressure fluctuation, and ensuring zero bypass during operation.
3. Integral Reinforced Support & Hot-melt Sealing Technology
The built-in rigid perforated support tube provides stable radial support for the filter medium, preventing medium shrinkage, collapse and deformation under long-term working pressure. The whole machine adopts full hot-melt sealing process without any adhesive filling, which completely eliminates the risk of adhesive dissolution and secondary medium pollution. The overall structure is firm and durable, adapting to 24-hour continuous industrial operation and long-term harsh working conditions.

It can efficiently remove free water, oil mist and solid fine particles in liquid and gas phase fluids. For special chemical media, please confirm with our technical team in advance to verify material compatibility.
Q3: What is the service life of LEFILTER CA11-8 replacement filter?
A3: The specific service life is affected by on-site fluid pollution degree, water content and operating flow rate. Under standard industrial working conditions, the conventional service cycle is 3–9 months. The most accurate replacement standard is system pressure difference; timely replacement is required when the pressure difference reaches 0.15MPa to ensure filtration stability.
Q4: What is the difference between CA11-8 and CA11-3 FACET coalescing filters?
A4: Compared with CA11-3, CA11-8 is optimized for high-flow working conditions, with larger dirt holding capacity and longer service cycle, suitable for medium and large flow fluid separation systems. The filtration precision and working temperature/pressure range of the two models are consistent, and users can select according to on-site flow parameters and equipment model.
