Product Overview
JFG-24 belongs to the JFG cylindrical natural gas coalescer series, designed as the medium-flow upgrade version of short-size JFG-12. The extended structure brings larger effective filtration area and higher dirt holding capacity, which can handle larger gas flow loads under identical housing diameter conditions. Different from tapered filter elements such as PCHG and JMG, the straight cylindrical structure achieves evenly distributed radial airflow, avoiding partial overload and local premature clogging of filter media during continuous long-term operation.

Working Principle
JFG series filters adopt mature inside-out gradient coalescing separation technology:
1. Raw natural gas mixed with liquid condensate, oil mist and solid impurities flows radially outward from the inner support core.
2. Multi-gradient filter media intercepts solid particles and captures tiny liquid aerosols, coalescing scattered micro-droplets into large liquid masses.
3. Separated liquid slides down the medium surface and is discharged by gravity through the drain system of the filter vessel.
4. Dry and purified gas enters downstream pipelines to complete gas-liquid-solid separation.
Key Features
- Medium-length cylindrical design: Larger filtration area than JFG-12 for higher gas handling capacity
- Uniform radial gas flow: Balanced utilization of the whole filter media to extend service cycle
- Gradient composite glass fiber media: Efficient interception of submicron liquid aerosols and solid pollutants
- Full perimeter metal sealing structure: Effectively avoid bypass filtration and guarantee outlet gas quality
- High rigidity anti-collapse inner support: Adapt to long-term operation under unstable pipeline pressure
- Complete series specifications: Flexible matching for small, medium and large flow gas purification projects
Application Scenarios
JFG-24 coalescing filter cartridges are extensively applied to medium-flow natural gas treatment links. Typical application scenarios include medium-sized gas gathering stations, city gate sub-stations, pipeline pressure regulation and metering skids, industrial boiler gas supply systems and petrochemical auxiliary process gas pipelines. By removing free water, condensate oil and solid particles in natural gas, the filter prevents liquid accumulation in pipelines, avoids precision meter failure and reduces wear on downstream compressors and control valves.
Product Advantages
1. Moderate length design balances flow capacity and installation requirements, suitable for most standard medium-sized filter vessels.
2. Higher dirt holding capacity than short-type JFG-12, lowering the frequency of element replacement and system shutdown.
3. Stable liquid coalescing efficiency ensures outlet gas meets dry gas standards for instrument and combustion equipment.
4. Slow pressure difference growth, which can maintain long-term stable operating efficiency in medium-pollution working conditions.
5. Unified standard dimensions realize plug-and-play replacement, convenient for spare parts inventory management and on-site maintenance.
FAQ
Q1: What is the flow difference between JFG-24 and JFG-12?
A1: JFG-24 has longer length and larger effective filter area. Under the same working conditions, its allowable gas processing flow is significantly higher than JFG-12, applicable to medium-flow systems.
Q2: Can JFG-24 be installed in filter housings originally designed for tapered PCHG filters?
A2: Not interchangeable directly. JFG series is straight cylindrical, while PCHG is conical structure. Confirm the internal structure of the vessel before ordering replacement elements.
Q3: Does the JFG-24 filter need a pre-filter in front?
A3: It is recommended to install a particulate pre-filter upstream to intercept large rust blocks and impurities, which can effectively slow down medium pollution and extend service life.
Q4: How to judge the replacement time of JFG-24 filter cartridge?
A4: When the inlet-outlet pressure difference rises continuously to the system set threshold, or liquid appears in the downstream gas, the filter element should be replaced in time.
Q5: Are JFG series replacement elements compatible with original PECO filter equipment?
A5: Yes. All overall length, outer diameter and end cap installation sizes are consistent with industry standards to achieve seamless replacement.
Q6: Can multiple different-length JFG elements be mixed and installed in the same filter vessel?
A6: Mixing installation is not advised. Different lengths will cause uneven flow distribution and reduce the overall filtration efficiency of the filter bank.
Q7: What storage conditions are required for unused JFG-24 filter cartridges?
A7: Keep sealed in original packaging, store in dry and ventilated environment at normal temperature. Avoid direct sunlight, heavy extrusion and long-term damp environment.
