The PCHG-24 is a 24-inch gas filter-separator cartridge from PECO‘s PCHG Series, designed for natural gas, manufactured gas, and other non-corrosive gases including nitrogen, carbon dioxide, propane, and butane. It is widely used in gas gathering stations, compressor stations, distribution stations, and terminal facilities where extended service intervals are beneficial.
The PCHG series is made using a patented process that provides increased flow, high efficiency, and effective removal of contaminants. This equates to increased operational life, fewer change-outs, reduced maintenance, and reduced costs. The synthetic construction allows for an environmentally friendly product and an excellent upgrade option to traditional fiberglass cartridges. PCHG cartridges remove contaminants such as asphaltenes, coal fines, dirt, iron sulfides, molecular sieve dust, pipe scale, salts, sand, and wear metals.
Compared to the 12-inch PCHG-12, the PCHG-24 offers double the filtration surface area, which translates directly into higher dirt holding capacity and longer service life. This makes it particularly suitable for applications where gas quality is variable or where maintenance access is limited and extended run times are valuable.
The PCHG-24 utilizes high-performance depth filtration media with a spiral-wound construction that creates a multidirectional, tortuous flow path. This design creates a true gradient depth filter that increases residence time for contaminant removal while maintaining porosity and permeability through the media. The media is thermally bonded without glue or binders, ensuring excellent chemical compatibility and eliminating the risk of media degradation from adhesive breakdown.
The gradient density structure means that larger particles are captured in the outer layers while finer particles penetrate deeper into the media, where they are trapped by progressively finer fibers. This depth loading mechanism prevents surface blinding and maintains consistent flow characteristics throughout the element’s service life.

Compressor & turbine suction: Protect compressor valves from abrasive contaminants
Contact towers (inlet & overhead): Remove contaminants before absorption processes
Custody transfer fuel gas: Prevent meter damage from particulates
Gas treating & dehydration: Remove molecular sieve dust and iron sulfides
Gas gathering systems: Remove sand, scale, and corrosion products

Q1: What is the difference between PCHG-24 and PCHG-12?
A: The PCHG-24 is 24 inches long, double the length of the PCHG-12. The extended length provides greater filtration surface area, higher dirt holding capacity, and longer service intervals between changeouts. It is ideal for applications where maintenance access is limited or where gas quality is variable.
Q2: What filtration accuracy options are available for PCHG-24?
A: Options range from 0.3μm to 10μm. For applications with precision equipment, 5μm or 10μm is recommended. For iron sulfide removal, 0.3μm is suggested. The choice depends on the specific contaminants present and the sensitivity of downstream equipment.
Q3: When should the PCHG-24 be replaced?
A: Replace when pressure differential reaches 12–15 PSID (0.8–1.0 bar). Maximum element differential pressure is 50 PSID with core. Regular pressure drop monitoring is the most reliable indicator of remaining service life.
Q4: Will LEFILTER’s PCHG-24 fit my existing filter housing?
A: Yes. PCHG-24 can be used in PECO Series 75 and Series 85 vessels, as well as several competitor filter-separator vessels of similar design. The 4.5“ OD × 24” length and DOE end cap configuration ensure compatibility.
