PCHG-336: High-Capacity PECO Replacement Natural Gas Filter Element

Product Overview

The PCHG-336 is a 36-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.

LEFILTER's replacement element matches the performance of the original PECO PCHG-336 cartridge, offering superior value with competitive pricing and shorter lead times.

Filtration Media Technology

The PCHG-336 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: Open pore structure maintains permeability while trapping particles

The PCHG-336 removes contaminants such as asphaltenes, coal fines, dirt, iron sulfides, molecular sieve dust, pipe scale, salt, sand, and wear metals.

Applications

The PCHG-336 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-336 and traditional FG series?
A: The PCHG-336 uses polyester depth media with a multidirectional, tortuous flow path creating a true gradient depth filter, offering higher contaminant loading and longer service life. The synthetic construction is environmentally friendly and represents an excellent upgrade option to traditional fiberglass "FG" style cartridges.

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, 0.1μm or 0.3μm is suggested.

Q3: When should the PCHG-336 be replaced?
A: Replace when the pressure differential reaches 12-15 PSID (0.8-1.0 bar). Maximum element differential pressure is 30 PSID without core or 50 PSID with core.

Q4: Will LEFILTER's PCHG-336 fit my existing filter housing?
A: Yes. The PCHG-336 can be used in PECO Series 75 and Series 85 vessels, as well as several competitor filter-separator vessels. The 4.5" OD × 36" dimensions and DOE end cap configuration ensure compatibility.
