Cartridge Filter - Duplex Housings

HD Process supplies DUPLEX style Cartridge Filter housings. A DUPLEX cartridge filter system pairs two full‑capacity housings in parallel, allowing operators to switch between trains without interrupting flow. This configuration is ideal for water treatment, chemical processing, plating lines, food & beverage, and general industrial filtration where uptime and consistency matter. Both 222 and 226 cartridges are supported, giving you flexibility across sealing styles, micron ratings, and media types.

Duplex have a list of benefits over a standard single housing including:

Uninterrupted Operation - With two housings online, one can be isolated for cartridge replacement, sanitisation, or maintenance while the other continues filtering. This eliminates shutdowns and protects critical processes.

Higher Flow Capacity - Running housings in parallel increases total throughput, reduces pressure drop, and allows finer micron ratings without sacrificing system performance.

Instant Changeover - A simple valve sequence switches flow from Train A to Train B in seconds. Operators gain predictable maintenance windows and safer handling conditions.

Redundancy & Reliability - Dual housings provide operational backup. If one train experiences fouling or unexpected loading, the second train maintains system integrity.
