In critical applications when vapor impurities a are a potential problem, the installation of a Clean Air Package provides the solution. Ultra clean air is provided by using the particulate ﬁlters as the ﬁ rst line of defense against gross contaminants found in all air lines. Elements remove solid particles larger than 5 micron, while automatic drains eliminate liquid water and oil emulsions that collect in the sump area. The particulate ﬁlter serves as a pre-ﬁter to extend the life of the more costly coalescing element used for the next stage of ﬁltration.
The coalescing ﬁlter element will further clean the air of residual oil mists, aerosols, and minute particles, larger than 0.3 micron. A standard differential pressure gauge warns when the pressure drop exceeds 8 to 10 psi, indicating that the coalescing element should be changed.
Finally, the adsorber ﬁ lter will provide air, virtually free of oil and most hydrocarbons. It effectively eliminates odors from freons, alcohols, esthers, ketones, and up to 99% of most hydrocarbons.
Clean Air Packages are available with port sizes ranging from 1/4 to 3/4.
