Compressed air is used in a variety of applications. For many applications, the air must be cleaned and filtered to remove contaminants. Among all the contaminants, oil mist and other liquid aerosols often pose the greatest challenge. In practice, nonwoven glass fiber media effectively remove these oil droplets. To preserve the structural stability of these coalescing media, a binder that holds the fibers together is employed. Most of the organic binders (acrylic or epoxy) have to be applied with an organic solvent. The use of a solvent not only poses a health problem, but also increases processing costs in the form of solvent disposal and recovery costs. This paper describes a use of a novel combination of B and E glass fibers that eliminates the organic binder and the solvent. Comparisons are made between this B–E-glass media and the traditional media with an acrylic binder. The results indicate that the B–E-glass media performs significantly better than the media with the organic binders both in terms of capture efficiency and quality factor.
