Products Description
The Paper Natural Gas Filter Cartridge 140×250 is a high-efficiency pleated cylindrical filtration element engineered for natural gas pipeline transmission, compressor stations, and gas purification systems.The filter media is constructed from high-quality multi-layer composite structure filter paper. This radially pleated pulp paper is typically polyester-reinforced and impregnated with phenol resin, providing enhanced mechanical strength and durability.
The cartridge features robust end caps-available in carbon steel or galvanized steel-and a durable inner support skeleton that provides structural integrity under high-pressure operation. As a custom-manufactured product, this filter element can be tailored to your exact specifications-whether you require a specific filtration rating, custom dimensions, or specialized sealing configurations.

FAQ
Q1: Is pleated paper better than flat paper for natural gas filtration?
A: Pleated construction can provide a much larger effective filtration area within a compact cartridge.
A larger filtration area can help provide:
- Higher flow capacity
- Lower initial pressure drop
- Greater dirt-holding capacity
- Longer service intervals
Commercial natural gas filters use pleated cellulose elements specifically to increase surface area and support longer operation.
A: A conventional natural gas particulate filter is primarily designed to remove solid contaminants, such as dust, rust, sand, and pipe scale.
A coalescing filter is specifically designed to remove fine liquid aerosols and droplets, including water and oil mist.
For systems containing both solids and liquids, a combination of particulate filtration and coalescing filtration may provide better protection.
Q3: Can a paper natural gas filter remove water and oil?
A: A standard paper/cellulose dry gas filter is primarily intended for particulate removal.
It should not be treated as a dedicated coalescing filter for removing fine water droplets, oil mist or hydrocarbon aerosols. When significant liquid contamination is present, a coalescing filter or filter separator is generally more appropriate. Natural-gas filtration references distinguish dry-gas particulate elements from coalescing cartridges designed for liquid droplets and mists.
A: Yes, but the installation position is important.
In many systems, upstream filtration is used to remove solids and bulk liquids before the compressor, while coalescing filtration may be installed downstream to remove compressor lubricant and fine liquid aerosols.
The appropriate configuration depends on the compressor type and the contaminants present in the gas stream.
