High-Quality PECO Replacement Natural Gas Filter Elements | Xinxiang Filter

Product Overview

Natural gas filter elements are essential components for gas-liquid and liquid-solid separation in natural gas, manufactured gas, and other non-corrosive gases including nitrogen, carbon dioxide, propane, and butane. These elements are critical separation and purification equipment for natural gas gathering and transmission pipelines, gas gathering stations, compressor stations, distribution stations, pigging stations, terminal stations, and various application fields. They effectively filter dirt, pipe scale, and peeling debris from pipe walls, ensuring safe operation of gas transmission equipment and meeting the quality requirements of pipeline transportation and end-users.

As a professional filter manufacturer based in Xinxiang, China (Stock Code: 837936), LEFILTER offers comprehensive replacement solutions for PECO brand filter elements. Our products deliver equivalent filtration performance at competitive prices with shorter lead times.

Product Technical Features

1. Advanced Filtration Media

Our PECO replacement filter elements utilize high-quality fiberglass and polyester fiber composite media. The unique spiral-wound construction creates a tapered structure with gradient density, providing radial, axial, and spiral flow paths that maximize contaminant loading capacity.

2. Superior Coalescing Performance

The coalescing filter element efficiently removes liquid aerosols and droplets from natural gas streams. Ultra-fine fibers capture oil and water droplets through direct interception, diffusion, and inertial impaction. Captured droplets coalesce into larger droplets, which then settle due to gravity.

3. Robust Construction

• Thermally bonded components: No glue or adhesive used, ensuring excellent chemical compatibility

• Reinforced core: Stainless steel or tin-plated carbon steel core provides structural integrity under high differential pressure

• High-quality seals: NBR (Buna-N) or Viton gaskets available for different temperature requirements

Applications

Our PECO replacement filter elements are widely used in:

• Natural gas gathering and transmission pipelines: Remove pipe scale, rust particles, and welding slag

• Compressor stations: Protect compressor valves and cylinders from abrasive contaminants

• Distribution stations: Ensure gas quality for end-users and prevent meter damage

• Gas turbine applications: Protect turbine blades from particulate contamination

• LNG and CNG facilities: Remove moisture and hydrocarbon liquids

• Petrochemical refining: Gas purification and liquid coalescence

FAQ – Frequently Asked Questions About PECO Replacement Filter Elements

Q1: What is the quality difference between LEFILTER replacement elements and genuine PECO filter elements?

A: LEFILTER replacement filter elements are manufactured to match or exceed the performance of original PECO elements. We use high-density gradient fiberglass and polyester fiber media, thermally bonded construction without glue, and stainless steel support cores. Our products are tested to ISO standards including ISO 2941 (burst pressure resistance), ISO 2943 (compatibility), and ISO 16889 (multi-pass filtration efficiency). Filtration efficiency reaches ≥99.9% for 0.3μm particles, equivalent to original performance.

Q2: How do I choose between PCHG series and FG series filter elements?

A: Both series are used in natural gas filtration, but they have different media types and applications:

• PCHG series: Uses polyester fiber synthetic media with spiral-wound construction. Offers excellent environmental friendliness, high contaminant loading capacity, and is suitable for applications with higher liquid content. The media is 100% synthetic and fully incinerable without residue.

• FG series: Uses fiberglass media, representing the original filter-separator technology PECO invented in 1954. Standard models use open end caps sealed with a reusable dimple washer, with optional closed top caps with bolt holes available.

Q3: What filtration accuracy should I select for my application?

A: Available accuracy options include 0.3μm, 1μm, 5μm, 10μm, and 20μm. For applications with precision instruments like turbine flow meters or gas compressors, we recommend 5μm or 10μm accuracy. For general pipeline coarse filtration, higher micron ratings can be selected. Models with "SCW" suffix indicate 0.3μm high-efficiency precision.

Q4: What are the maximum operating temperature and pressure drop limits?

A: Temperature limits depend on media type:

• Polyester media: Maximum 115°C (240°F). For applications above 200°F, a support core is recommended.

• Polypropylene media: Maximum 80°C (180°F).
  Recommended replacement pressure drop threshold: 0.08-0.1 MPa (approximately 12-15 psi). Maximum allowable pressure drop: ≤0.17 MPa
