In-Line Filters Valco Melton provides both "Old style" and "New Style" filters. These old style filter assemblies use a basket style filter which is housed in between the two halves of the filter assembly. These filter assemblies must be disassembled in order to change the filter cartridge. The "Mars" style filters are directly interchageable with the Nordson "Saturn" series in-line filter and cartridges |
