Dual Vessel Cartridge Unit

The Dual Vessel Cartridge Filter Unit is based on 25 years of experience in manufacturing oilfield equipment. Developed with direct input from our customers, our unique twin vessel filter unit brings together proven performance and innovative features in one reliable and efficient solution. HSE (Health, Safety & Environment), efficiency and reliability are the key drivers for our product improvement and design.

For the vessel closure, you can opt for our Rudi Quick Opening Closure, which enables fast, safe, and tool-free filter change-outs—minimizing downtime and improving operator safety.

The unit is engineered and built in full compliance with DNV 2.7-1 / ISO 10855 / EN 12079 standards, and certified by DNV or Lloyd’s Register. Our standard DFC24 unit has two housings with each 50 cartridges and 6 valves for parallel, in series and by-pass operation.

The Dual Vessel Filter unit is also available as Dual Vessel Bag Filter Unit and Dual Vessel Combi Filter Unit.
