Numatics 22 and 32 Series Compressed Air Coalescing Filter
.03 Micron sintered element with manual drain and Polycarbonate bowl.
Used when either clean air is required or longer component life is desired. This type of filter removes water and oil aerosols. Working differently than particulate filter, oily air enters the element from its center and passes through a field of glass fibers which cause the aerosols to form into heavier-than-air droplets. The droplets grow larger as they pass through the element and gravity drains the oil drops to the sump of the bowl. With the harmful oil varnishes and and contaminants that attack seals and gaskets now removed, the valve or cylinder is much less likely to stick. It should always be used AFTER a 5 micron particulate filter.
