FO-718PL05 domestic interchangeable gas pipeline pre particle filter fiberglass filter cartridge

The FO series is a benchmark filter element in the natural gas industry. It is mainly used to efficiently remove solid particles and liquid impurities (such as water and oil) from natural gas, thereby protecting downstream key equipment such as compressors and flow meters.

Product Introduction

The technical advantage of FO series filter cartridges comes from their precise material combination and structural design:
1. Graded fiberglass media - deep filtration without channels
The filter element is made of resin impregnated glass fiber medium, arranged layer by layer according to the fiber diameter. This structure ensures that the collected particles are evenly distributed throughout the filter body, avoiding early failure caused by surface blockage of traditional filters and achieving efficient deep filtration without channels.
2. Positive medium migration barrier - eliminating secondary pollution
The filter element is equipped with a cellulose barrier layer impregnated with resin, effectively preventing the migration of glass fibers to downstream media. This design is particularly important for protecting precision equipment such as downstream compressor dry gas seals and measuring instruments.
3. High strength central tube - anti crushing guarantee
The heavy-duty aluminum plated steel center pipe is not only corrosion-resistant, but also provides a compressive strength of 100 psi. Laboratory tests have shown that the average compressive strength of FO-472G exceeds 100 psid, while a mainstream competitor only has 34 psid.
4. Resin coated fiberglass mesh - maintains its shape and is easy to maintain

The glass fiber mesh coated with outer resin maintains its shape and density throughout the entire life cycle of the filter element, resisting handling damage while reducing the accumulation of external dirt.


The FO series filter element is a key component in the natural gas processing process

Natural gas gathering and transmission pipelines: gas gathering stations, compressor stations, distribution stations, pipeline cleaning stations, terminal stations, etc.

Natural gas purification plants, long-distance pipeline stations.

Urban gas transmission and distribution network, gas power plants.

Non corrosive gas filtration: gas-liquid and liquid-solid separation of gases such as nitrogen, carbon dioxide, propane, butane, etc.
