PECO FG-312 Heavy-Duty Natural Gas Coalescing Filter Cartridge

Product Overview

PECO FG-312 is a compact heavy-duty precision model in the PECO FG-3 upgraded coalescer series. Compared with conventional FG-12 short filters, FG-312 uses thicker multi-layer composite media and optimized fiber stacking density, significantly improving micro-aerosol interception accuracy and pressure resistance. Its short-body compact structure is suitable for narrow-space filter vessels where long-size elements cannot be installed, solving the problem of insufficient precision of ordinary short filters.

Our replacement FG-312 filter cartridge adopts industrial upgraded oleophilic and hydrophobic glass fiber media. The dense gradient structure can capture submicron liquid aerosols that easily penetrate standard filters, realizing deep gas-liquid separation. The integrated integral metal end cap forms a fully enclosed sealing system to completely avoid gas bypass and ensure full-media effective filtration. The reinforced internal support tube effectively resists pressure impact and media deformation under frequent gas pressure fluctuations, maintaining long-term stable precision filtration performance. With compact size, high precision and strong durability, FG-312 is widely used in high-standard small and medium-flow gas purification scenarios.

Working Principle

FG-312 adopts PECO’s upgraded compact high-precision coalescing separation principle:

1. Impure natural gas containing micro liquid aerosols and fine solid dust flows radially outward from the inner support core.

2. High-density gradient oleophilic media accurately intercepts tiny aerosol droplets and coalesces them into large liquid molecules.

3. Coalesced liquid gathers on the outer media surface and flows downwards for centralized discharge by gravity.

4. High-purity dry gas passes through the filter layer stably, completing high-precision gas-liquid-solid three-phase purification.

Application Scenarios

FG-312 precision coalescing filter elements are mainly applied in high-precision gas purification scenarios with limited installation space, including precision instrument gas supply systems, gas metering station calibration equipment, small and medium gas pressure regulating stations, laboratory gas pretreatment devices and petrochemical fine gas purification units. As core precision separation components, they effectively eliminate micro liquid aerosols and fine dust, ensure high dryness and purity of natural gas, and protect downstream precision instruments, sensors and regulating valves from micro-corrosion and blockage failure.
