Often called the pre-filter since it
is placed on the air line just prior to the air dryer, a
coalescing filter assembly removes oil, particles and moisture
before it can come in contact with the desiccant in the dryer and ruining it.
Coalescing filters capture oil, moisture and particles, binding
them together until their mass is heavy enough for gravity to send
this waste to a drain valve. A coalescer filter is often
called a pre-filter because it is usually located prior to an air
dryer to prevent oil and particulate from soiling the desiccant.
