COALESCER

Pneumatech's Micro-glass fiber technology and unique element tube configuration combine to deliver high efficiencies with 30% greater flow per unit of size. Complimenting these coalescing elements are Pneumatech's "deep bowl" design housings (large sump capacity) designed specifically for compressed air oil removal applications.

Coalescing is a process whereby liquid aerosols, by contact with fine glass micro-fibers, are agglomerated into larger and larger droplets until they are gravitationally drained away. A micron, identified by the symbol "µ", and also known as a mircrometer is one millionth of a meter (0.000039 inches) in size. Human hair is approximately 80 microns in diameter, while a grain of table salt is approximately 100 microns in size. 40 microns is the lower level of visibility to the human eye. The coalescing process occurs in three distinctly different manners depending on the aerosol size:

  1. DIRECT IMPACT - contaminants greater than 2um have sufficient mass and develop enough momentum to leave the air flow stream. These contaminants collide with the filter media because of their size.
  2. INTERCEPTION - collects contaminants between .2 and 2um, which are the most difficult to remove. Glass fibers of a diameter no larger than the aerosol diameter (typically average pf .5,um) optimize performance in this range.
  3. DIFFUSION - aerosols in the .001 to .2pm follow a random motion and strike the micro-glass fibers. Solid contaminants adhere permanently to these surfaces. Aerosols, however, migrate gravitationally along the fibers, join other droplets to form larger masses of liquid which fall out and can be drained from the system.

Coalescing of a liquid does not clog the filter, solid particles do. The unique, vacuum formed, fiber matrix we use for coalescing also forms a highly efficient and long lived particulate filter.
