4.4  Functional description
4.4.1  Filtration
Medium ows through the coalescing lter from the inside to the outside. Compressed air enters the interior of the 
lter element and from there passes through the lter element and into the lter container. The solid materials and oil 
and water droplets in the lter material are separated. Gravity causes the liquid part of the lter material to move down, 
drip and collect below in the lter container. From there, it is manually or automatically drained. Over time, particles 
build up in the lter material. The ow resistance (dierential pressure) of the lter element increases as a consequence.
The degree of particle load or contamination of the lter element can be read o on a dierential pressure gauge. 
Further information is provided in the installation and operating manual included with the dierential pressure gauge.
