Coalescer cartridges are offered in a variety of cartridge configurations to replace current industry cartridges. They are available with double open ends and flat gaskets, open ends with O-Ring seals, and thread base construction. Cartridges are available in a number of different diameters and lengths. All coalescers are single piece construction, resulting in increased strength and reducing the chance of bypass. We use a combination of one or more layers of pleated media and various layers of fiberglass.
