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.
