Coalescing Filter Elements
Coalescing Filter Elements
At Dantechs System and Filter Solutions, we offer coalescing filter elements designed to remove micro-liquid aerosols and hydrocarbons mixed into the gas phase in natural gas transmission pipelines, petrochemical plants and compressor stations. These specialised cartridges are vertical circular counter-flow systems that operate on the principle of gas flowing from the inside to the outside of the filter element. As the gas passes through the media, micro-sized liquid droplets coalesce and grow (the coalescing effect), reach the outer wall of the cartridge and, aided by gravity, drain into the lower collection chamber, thereby being completely removed from the gas stream.
Filtration Precision and Performance Levels
Our JRGC series filter elements capture both liquid and solid contaminants in your gas flow at sizes of 0.3 microns and above with an absolute efficiency of up to 99.99 per cent:

Hardware Specifications and Operating Limits
- Advanced Layer Technology: Whilst the inner layer consists of depth-type polyester or polypropylene media, the outermost layer features a Needled Polyester Drain Layer, which effectively prevents re-entrainment of separated liquids into the gas stream.
- Material Durability: Tin-plated steel, stainless steel or nylon fittings are available for the inner core and end caps.
- Maximum Operating Temperature: 240°F (~115°C) for polyester (E) media (a metal inner core is mandatory at temperatures above 200°F). 180°F (~82°C) for polypropylene (F) media.
- Recommended Change-out Differential Pressure (PSID): Cartridge replacement is recommended at a differential pressure of 12–15 PSID (0.8–1.0 bar) to ensure optimal operating costs and mechanical protection.
