Coalescing Cartridges

 

Often called the pre-filter since it is placed on the air line just prior to the air dryer, a coalescing filter removes oil, particles and moisture before it can come in contact with the desiccant in the dryer and ruin it.

 

Tiny droplets of water contact and adhere to strands of fiberglass. Flow pushes the droplets along the strand until they reach an intersection of strands where they combine with other droplets and (coalesce) into larger drops.

 

These large drops are then carried to the outside surface of the cartridge. Having a higher specific gravity than the hydrocarbon fluid, they release and settle to the bottom of the vessel. The larger the drops, the faster and more efficiently they fall out. In general, particle removal efficiency increases with coalescing efficiency. This is accomplished by employing a tighter, finer filtration media.
