JFG-324 Natural Gas Coalescing Filter Cartridge | Aftermarket Cylindrical Gas Separation Element

Product Overview

JFG-324 belongs to the extended-length model within the JFG cylindrical coalescing filter series. Compared with shorter specifications such as JFG-12, JFG-24 and JFG-36, the increased length expands the effective filtration area and improves contaminant holding capacity, which helps extend service intervals in facilities running 24 hours a day. The straight cylindrical design delivers even radial gas distribution across the entire media surface, avoiding partial overload and uneven contamination commonly seen on tapered filter cartridges.

This interchangeable filter element adopts staged gradient composite fiber structure. Outer coarse fiber layers capture large solid impurities including pipeline rust and debris, while inner fine fiber layers trap micro liquid aerosols and combine scattered droplets into large separable liquid masses. Coalesced liquid flows down along the filter surface under gravity and drains through the drainage system of filter vessels. Precision machined metal end caps form full perimeter sealing to avoid gas bypass and short-circuit flow. The reinforced perforated inner support tube keeps the media intact under frequent pipeline pressure swings. The complete JFG series lineup includes JFG-12, JFG-24, JFG-36, JFG-312, JFG-324, JFG-336, JFG-372, JFG-536, JFG-572. Users can choose suitable specifications according to system flow rate and filter housing internal dimensions.

Working Principle

JFG series coalescing filters adopt proven inside-out gradient coalescing separation technology:

1. Contaminated natural gas carrying condensate, oil mist and solid particles flows radially outward from the inner support core.

2. Multi-gradient filter media intercepts solid pollutants and captures tiny liquid aerosols, coalescing micro droplets into large liquid masses.

3. Coalesced liquid slides down the outer surface of filter media and is discharged by gravity via the drain port of filter housing.

4. Clean and dry gas flows toward downstream pipelines to finish gas-liquid-solid three-phase separation.

Key Features

- Extended cylindrical structure: Larger filtration area to satisfy high gas flow demands

- Balanced radial airflow design: Uniform media utilization to prolong service life

- Gradient oleophilic-hydrophobic glass fiber media: Efficient removal of submicron liquid aerosols and particles

- Fully sealed metal end cap construction: Prevent bypass filtration and maintain stable outlet gas quality

- Rigid reinforced inner support skeleton: Resist media deformation under continuous high-flow impact

- Complete series specifications: Flexible selection for small skids and large trunk pipeline facilities

Application Scenarios

JFG-324 coalescing filter cartridges are widely deployed for high-flow natural gas treatment. Typical application sites cover long-distance trunk transmission stations, large centralized gas gathering stations, main city gate stations, gas-fired power plants and petrochemical process gas pretreatment systems. The filter removes free water, hydrocarbon condensate and solid impurities in raw natural gas, reducing pipeline corrosion risks and avoiding equipment faults caused by liquid and particle contamination.

Product Advantages

1. Extended length brings greater dirt holding capacity, lowering element replacement frequency and system downtime losses.

2. Standard cylindrical shape matches most mainstream horizontal filter vessels for convenient replacement.

3. Reliable liquid coalescing performance ensures outlet gas meets strict dryness standards for instrument gas supply.

4. Moderate flow resistance reduces overall energy consumption of gas transmission systems during long-term operation.

5. Unified installation dimensions simplify spare parts inventory management for gas operation enterprises.

FAQ

Q1: What are the differences between JFG-324 and JFG-312?

A1: JFG-324 features longer overall length and larger filtration area. It supports higher gas handling flow and longer service cycles for heavy-load natural gas transmission stations.

Q2: Can JFG-324 be used to replace tapered PCHG filter cartridges?

A2: Direct replacement is not available. JFG series adopts straight cylindrical structure while PCHG uses tapered design. Confirm filter housing internal structure before ordering.

Q3: Is pre-filter equipment required upstream of JFG-324?

A3: It is recommended to install a particulate pre-filter upstream to intercept large solid debris, effectively delaying media fouling and extending service life.

Q4: How to judge the replacement time of JFG-324 filter cartridge?

A4: Replace elements in time once inlet-outlet differential pressure rises to the preset threshold, or liquid carryover occurs in downstream purified gas.

Q5: Does JFG-324 fit standard PECO natural gas filter housings?

A5: Yes. All key installation dimensions comply with industry standards to realize seamless plug-and-play replacement.

Q6: Can different-length JFG filter elements be mixed inside one filter vessel?

A6: Mixed installation is not recommended. Different lengths will lead to uneven gas distribution and reduce overall filtration efficiency of the filter bank.

Q7: What storage requirements apply to unused JFG-324 filter cartridges?

A7: Keep sealed in original packaging and store in dry and ventilated environments. Avoid direct sunlight, heavy extrusion and long-term damp conditions before installation.
