Application Scenarios
Applicable Working Sites: This aftermarket PECO FG-336 filter cartridge is specially designed for heavy-duty industrial natural gas purification scenarios, including large-scale natural gas gathering stations, long-distance gas transmission trunk lines, gas pressure regulating and metering stations, petrochemical gas processing plants and LPG processing systems. It is widely applied in upstream and midstream natural gas industrial filtration projects.
Core Filtration Function: Adopting high-performance borosilicate glass fiber coalescing media, the filter efficiently removes solid contaminants such as pipeline rust, scale, sand and dust. It also coalesces and separates free water, oil mist and hydrocarbon condensate entrained in natural gas streams, realizing high-precision gas purification.
Downstream Equipment Protection: Fully compatible with standard PECO filter separator vessels, this direct replacement filter effectively protects core precision equipment including large-flow gas compressors, flow meters, control valves and instrumentation systems. It avoids equipment abrasion, clogging and corrosion caused by mixed impurities, ensuring stable system operation.
Industry Adaptability: Suitable for onshore large gas fields, chemical plant gas supply, municipal natural gas transmission and other high-load continuous operating conditions. It maintains stable filtration performance under long-cycle non-stop industrial operation.

100% OEM Interchangeable: Our FG-336 replacement filter is strictly manufactured according to OEM dimensional and structural standards. It perfectly matches the original PECO filter housing with no modification required, supporting plug-and-play installation to save time and labor costs.
Reliable Filtration Performance: The gradient glass fiber material features uniform pore size, high dirt-holding capacity and stable pressure drop. It delivers consistent and efficient filtration effect throughout the service life, fully meeting OEM technical performance standards.
High Cost-Effectiveness: Compared with the expensive original PECO FG-336 filter elements, our aftermarket products provide identical reliable working performance at a much lower price. It effectively reduces customers’ long-term procurement, operation and maintenance costs.
Flexible Customization: We support personalized customization of filtration precision, sealing materials and product specifications. Custom solutions can be provided to adapt to different complex working condition requirements.
Quality Assurance
Standardized Production: All FG-336 filter cartridges are produced in strict accordance with international industrial filtration standards and standardized production processes to ensure stable and reliable overall quality.
