The removal of aerosols from sample gas streams is a request in numerous applications.
An appropriate answer is the use of a coalescing filter. This filter is equipped with an element made of borosilicate fibers. The gas stream is passing the element from inside to outside. The aerosols are caught in the matrix and form steadily growing droplets which finally drop down into the bowl as liquid phase.
The lifetime of the elements depends on the particulates also carried by the gas stream. If they are retained upstream the coalescer filter the life time of the filter element is almost unlimited.
The liquid collected in the bowl is drained off by either a condensate drain or a peristaltic pump.
