JFS-336 Natural Gas Separator Filter Cartridge | Conical Gas Purification Separation Element
Tailored for two-stage coalescing separator equipment in natural gas industry, JFS-336 filter cartridge functions as high-performance secondary separation component to trap free water droplets, natural gas condensate, and micro solid contaminants inside process gas streams. This tapered element adopts multi-layer gradient hydrophobic composite fiber media, specially engineered to intercept large liquid droplets formed by upstream coalescing filter cartridges. It sustains consistent separation efficiency under unstable gas flow and pressure fluctuations, providing reliable protection for downstream compressors, precision flow meters, pressure control valves and pipeline infrastructure against liquid corrosion and particle erosion. With standardized outer dimensions, JFS-336 serves as an ideal interchange spare part for gas gathering stations, city gate stations and long-distance transmission pipeline facilities.
Product Introduction
Product Overview
JFS-336 separation filter features classic conical outline, fully compatible with widely used vertical natural gas separator housings. The built-in heavy-duty reinforced inner support cage delivers stable structural strength under high gas velocity, preventing expansion, deformation or damage of filter media. The hydrophobic fiber surface inhibits liquid adhesion, enabling captured droplets to flow downward along the cone for gravity separation. The filter material possesses outstanding tolerance to natural gas condensate, methanol, glycol and other pipeline additives, maintaining stable performance under long-time 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.
Our product portfolio also contains matched natural gas filter series including PCHG, FG, JFG, JMG and G series to supply complete gas purification system solutions for different industrial projects.
Working Principle
Gas carrying aggregated liquid droplets flows from outside inward through the medium of JFS-336 filter cartridge.
Tiny liquid droplets impact hydrophobic fiber layers and get retained on the outer surface of filter material.
Captured liquid droplets keep combining and growing bigger, sliding down the tapered surface under gravity force.
Separated liquid accumulates in the bottom sump of filter vessel; dry purified natural gas flows towards downstream pipeline network.

FAQ
Q1: What is the main role of JFS-336 filter cartridge?
A1: JFS-336 belongs to secondary separation filter. It removes coalesced liquid droplets and fine solid particles from natural gas after primary coalescing filtration to obtain dry and purified natural gas.
Q2: Can JFS-336 work independently without coalescing filter?
A2: Not suggested. This model is designed to cooperate with upstream coalescing filter elements. Independent usage will result in rapid medium clogging and unsatisfactory separation efficiency.
Q3: What temperature range can JFS-336 withstand?
A3: Continuous operating temperature ranges between -40℃ ~ 120℃, adapting to most outdoor natural gas pipeline operation environments.
Q4: Can JFS-336 be used for natural gas containing hydrogen sulfide?
A4: Standard version is suitable for non-corrosive natural gas. For medium with high H₂S concentration, customized anti-corrosion materials for end caps and support frame are available.
Q5: When do we need to replace JFS-336 filter cartridge?
A5: Replace the filter when the pressure difference of filter vessel reaches preset warning threshold, or liquid carryover appears at the gas outlet.
Q6: Can JFS-336 directly replace other JFS series models?
A6: It cannot. JFS-312, JFS-324, JFS-336 and other models differ in length and diameter. You must choose the exact model matching your existing filter housing.
Q7: Is customized size service available for JFS-336?
A7: Yes. We can provide customized length, end interface structure and filter media formula according to customer drawings and technical specifications.
