PECO FG-336 Ultra-High Precision Natural Gas Coalescing Filter Cartridge

Product Overview

PECO FG-336 is the flagship long-type model of the FG-3 heavy-duty high-precision coalescer series. Compared with FG-312 and FG-324 medium and short models, FG-336 adopts the longest effective filtration size with full dense upgraded media layer. It perfectly solves the industry pain points of insufficient precision of standard FG series filters and low throughput of small high-precision elements. The classic straight cylindrical structure realizes uniform radial gas flow, avoiding flow dead zones and local pressure surge even under 24/7 full-load high-flow operation.

Our replacement FG-336 filter element adopts top-grade industrial thickened oleophilic-hydrophobic glass fiber media. Through multi-layer gradient density optimization, the filter achieves staged interception from large particles to submicron aerosols, realizing industry-leading deep gas-liquid separation. The fully sealed integral metal end cap completely eliminates gas bypass and short-circuit filtration, ensuring every gas molecule passes through effective media layers. The thickened reinforced internal support pipe features extreme pressure resistance and anti-collapse performance, maintaining stable structural shape and consistent filtration efficiency under long-term high pressure and fluctuating working conditions. FG-336 is the ultimate combination of high precision, high flow and long service life in the PECO replacement filter series.

Working Principle

FG-336 adopts PECO’s flagship full-gradient deep coalescing separation mechanism:

1. High-flow contaminated natural gas containing trace oil mist, micro liquid aerosols and fine dust flows radially outward from the inner core.

2. Ultra-dense gradient heavy-duty media captures submicron liquid impurities and coalesces tiny aerosols into large liquid droplets.

3. Coalesced liquid accumulates on the outer media surface, forms liquid films and flows down rapidly by gravity for automatic discharge.

4. Ultra-dry, high-purity natural gas is output stably, completing high-standard gas-liquid-solid three-phase deep purification.
