JFS-312 Natural Gas Separator Filter Cartridge | Conical Gas-liquid Separation Element
Designed for two-stage natural gas purification equipment, the JFS-312 filter cartridge is a tapered secondary separation component built for removing free liquid droplets, hydrocarbon condensate and fine solid pollutants from natural gas flow. Constructed with multi-layer gradient hydrophobic composite media, this element efficiently captures aggregated liquid droplets formed by upstream coalescing cartridges. It maintains stable separation efficiency under variable gas flow pressure, effectively shielding downstream compressors, metering instruments and pipeline facilities from liquid erosion and particle abrasion. Widely matched with standard vertical natural gas filter separators, JFS-312 is a reliable aftermarket replacement solution for gas station filtration systems.
Product Introduction
Product Overview
The JFS-312 separation filter adopts a conical structural design, perfectly compatible with mainstream separator housings used in natural gas transmission facilities. The internal reinforced support cage delivers outstanding structural stability under high gas velocity, preventing medium deformation. The special hydrophobic filter material repels liquid, enabling captured droplets to slide downwards for gravity separation. Resistant to natural gas condensate, methanol and glycol pipeline additives, the filter avoids performance degradation under long-cycle continuous operation.
Complete JFS series model range: JFS-312, JFS-324, JFS-336, JFS-348, JFS-372, JFS-512, JFS-524, JFS-536, JFS-548, JFS-572.
We also supply matching natural gas filter series including PCHG, FG, JFG, JMG and G series to build full-set gas purification solutions for customers.
Working Principle
Purified gas containing aggregated liquid droplets flows from outside to inside through the JFS-312 filter medium.
Liquid droplets impact the hydrophobic fiber layer and are intercepted on the filter surface.
Captured droplets continuously combine and grow larger, sliding downward along the taper surface by gravity.
Liquids separate from gas and drain to the vessel sump; dry purified natural gas flows to downstream pipelines.
Key Features

Application Scenarios
JFS-312 natural gas separation filter is commonly installed in natural gas gathering stations, pressure regulating metering stations, city gate stations and small compressor stations. It performs secondary separation after coalescing filters, eliminating residual free water and hydrocarbon liquid inside gas. It can also be used for gas-liquid separation of nitrogen, CO₂ and other industrial non-corrosive gas, protecting precision instruments and gas transmission equipment.

FAQ
Q1: What is the function of JFS-312 filter cartridge?
A1: JFS-312 belongs to secondary separation filter. It removes coalesced liquid droplets and fine solid particles from natural gas after primary coalescing filtration to obtain dry clean gas.
Q2: Can JFS-312 work alone without coalescing filter?
A2: Not recommended. It is designed to cooperate with upstream coalescing elements. Independent use will lead to rapid blockage and poor separation effect.
Q3: What temperature can JFS-312 withstand?
A3: Continuous operating temperature range is -40℃ ~ 120℃, adapting to most outdoor natural gas pipeline working environments.
Q4: Can JFS-312 be used in natural gas containing hydrogen sulfide?
A4: Standard version applies to non-corrosive clean natural gas. For high H₂S medium, we can customize anti-corrosion material for end caps and support frame.
Q5: How to judge when to replace JFS-312 filter?
A5: Replace the cartridge when the pressure difference of filter vessel reaches the preset warning value, or liquid carryover phenomenon occurs at the gas outlet.
Q6: Is JFS-312 interchangeable with other JFS models?
A6: No. JFS series like JFS-312, JFS-336, JFS-572 differ in length and outer diameter. You need to select the exact model matching your filter housing.
Q7: Can you provide customized size based on JFS-312?
A7: Yes. We support customized length, interface structure and filter media formula according to customer drawings and technical requirements.
