Coalescing Filters

 

Coalescing is the separation of liquid aerosols and 

droplets from a gas. Using a coalescing filter element 

installed in a housing with three ports the wet gas 

sample passes though element inside to outside. 

The inner capture layer is a high efficiency coalescing

layer and the outer is a coarser drainage layer.

 

The fine fibres of the inner layer capture the fine liquid 

aerosols and droplets and they run together along the 

fibres to form large drops within the depth of the 

element. These large drops are then forced  to the 

outside of the filter element and then drain to the 

bowl of the housing by gravity. Coalescing filter 

elements will also remove particulates at the same  

efficiency as particulate type elements of the 

same grade.
