LG Liquid and Gas Coalescing Filter Cartridges

Dewdon LG coalescing filter cartridges are designed for critical air or gas service applications where high-efficiency removal of oil or water droplets and particulate solids is required. This series of coalescers offers proprietary aerosol interception, liquid coalescence, and liquid drainage layers, co-pleated to ensure a sturdy, high surface area, low-pressure drop system.

Dewdon’s unique micro-fiber media ensures efficient separation of liquid aerosols from gas streams while minimizing fluid retention. Dewdon Filtration offers replacement Elements for Peco, Jonell, Porous Media, Pall and most other Vertical Gas Coalescing Vessels.
