KELTEC Technolab Coalescing Filters provide an effective way to protect compressed air systems and downstream equipment from contamination. Even in applications using “oil-free” compressors, atmospheric air often contains water vapor, oil aerosols, and particulate matter that can negatively impact system performance and equipment reliability. Proper coalescing filtration helps control these contaminants before they reach sensitive components.

KELTEC coalescing filters are engineered to deliver high levels of compressed air cleanliness with minimal energy loss. Through the careful selection of borosilicate microglass filtration media, and strict control of fiber quantity, diameter, and orientation, these filters are designed to promote efficient coalescence while maintaining low pressure drop. This balance supports reliable system operation with reduced maintenance demands over time.

To address bulk liquid removal, KELTEC Technolab Water Separators (KWS) are available as a complementary solution. These separators use centrifugal action to remove liquid water and a significant portion of particulate contamination from compressed air and gas streams. Designed for energy efficiency, KWS water separators operate at low pressure drop. When used together, coalescing filters and water separators form an effective compressed air contamination control strategy.
