PCHG-72: Extended Length PECO Replacement Natural Gas Filter Element

Product Overview

The PCHG-72 is a 72-inch gas filter-separator cartridge 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 required.

LEFILTER's replacement element matches the performance of the original PECO PCHG-72 cartridge, offering superior value with competitive pricing and shorter lead times.

Filtration Media Technology

The PCHG-72 utilizes high-performance depth filtration media with the following key features:

• Spiral-wound construction: Media layers are thermally bonded and spiral-wound to form a conical helix pattern

• Gradient density structure: The unique multidirectional, tortuous flow path creates a true gradient depth filter that increases residence time for contaminant removal while maintaining porosity and permeability through the media 

• No glue or binders: Thermally bonded construction ensures excellent chemical compatibility

• High contaminant loading capacity: Extended length provides greater surface area and higher dirt holding capacity compared to standard 36-inch models 

The PCHG-72 removes contaminants such as asphaltenes, coal fines, dirt, iron sulfides, molecular sieve dust, pipe scale, salt, sand, and wear metals .

Applications

The PCHG-72 replacement filter element is ideal for:

• City Gate stations: Ensure gas quality before distribution 

• 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 Distribution & Transmission: Remove pipe scale, rust, and welding slag 

• Gas Treating & Dehydration: Remove molecular sieve dust and iron sulfides 

• Landfill Gas: Purify gas for downstream treatment

FAQ

Q1: What is the difference between PCHG-72 and PCHG-36?
A: The PCHG-72 is 72 inches long, double the length of the PCHG-36. This extended length provides greater filtration surface area, higher dirt holding capacity, and longer service intervals between changeouts. It is ideal for high-volume gas transmission applications where reduced maintenance frequency is critical .

Q2: What filtration accuracy options are available?
A: We offer options from 0.3μm (SCW) to 10μm. For applications with precision equipment, 5μm or 10μm is recommended. For filtering iron sulfide particles, 0.3μm is suggested .

Q3: When should the PCHG-72 be replaced?
A: Replace when the pressure differential reaches 15 PSID (1.0 bar). Maximum element differential pressure is 30 PSID without core or 50 PSID with core .

Q4: Will LEFILTER's PCHG-72 fit my existing filter housing?
A: Yes. The PCHG-72 can be used in PECO Series 75 and Series 85 vessels, as well as several competitor filter-separator vessels. The 4.5" OD × 72" dimensions and DOE end cap configuration ensure compatibility .
