RELIABLE FILTRATION FOR INDUSTRIAL LIQUIDS: INSIDE THE PARKER EH MULTI-CARTRIDGE FILTER VESSEL

In demanding industrial environments, reliable and efficient liquid filtration is essential to ensure product quality, system protection, and operational uptime. The Parker EH Multi-Cartridge Filter Vessel delivers the durability, versatility, and performance required for today’s process industries—from food and beverage to chemicals, coatings, and lubricants.

Built for Strength and Versatility

Engineered from 304 or 316L stainless steel, the EH series is designed for economical, high-performance filtration across a wide range of liquids. The vessels accommodate multiple cartridge lengths—10″, 20″, 30″, or 40″—and support both Double Open End (DOE) and Single Open End (SOE 222 O-ring) cartridges, allowing flexibility for different filtration setups.

With a maximum operating pressure of 150 psi (10.3 bar) and temperature resistance up to 300°F (149°C), these vessels perform reliably under demanding process conditions. Their swing bolt closure enables fast, tool-free access for cartridge replacement, minimizing downtime during maintenance.

Corrosion Resistance and Hygienic Design

The EH vessel’s polished exterior and pickle-passivated interior enhance corrosion resistance—making it ideal for applications involving potable water, lubricants, edible oils, solvents, and coolants. Stainless steel hardware on all pressure and support components ensures long-term durability and contamination-free operation.

Available in threaded (FNPT) or flanged connection models, the EH series integrates seamlessly into both new and existing process lines. Optional seal materials—EPDM, Buna-N, or Viton® (FKM)—allow compatibility with various chemical formulations.

Designed for Flexible, Scalable Filtration

When designing systems for variable production volumes and fluid types, the Parker EH Multi-Cartridge Filter Vessel stands out with its flexible cartridge configuration.

It supports both DOE (Double Open End) and SOE (222 Single Open End) cartridges in lengths from 10″ to 40″, making it easy to scale from pilot lines to full production without changing the entire setup. With flow capacities ranging from 25 to 380 gpm, this vessel delivers consistent filtration performance across applications—ideal for food & beverage, chemical, and industrial process environments.

Engineered for Easy Maintenance and Long-Term Reliability

The EH series is designed with uptime in mind. Its swing-bolt O-ring closure provides tool-free, quick access for cartridge replacement—reducing maintenance time and minimizing production downtime.

Built from polished and passivated 304/316L stainless steel, both interior and exterior surfaces ensure superior corrosion resistance and hygiene for fluids such as lubricants, solvents, edible oils, and water. Together, these design advantages support cleaner operation, simpler maintenance, and longer system life in demanding industrial conditions.

Note From Our Expert

“Choosing the right filtration vessel isn’t just about meeting flow rate or pressure specs—it’s about ensuring long-term process reliability,” says our Technical Specialist at Domnick (Thailand).

“The Parker EH Multi-Cartridge Filter Vessel combines strength, chemical resistance, and hygienic design in a way that supports both efficiency and safety. For industrial operators, that means fewer shutdowns, easier maintenance, and cleaner process outcomes across multiple applications—from food-grade production to lubricant and solvent filtration.”
