Stainless Steel Cartridge Filter Housing
AISI 304, 304L, 316, 316L and 316Ti Stainless Steel Body and 1–60 Cartridge Capacity
A cartridge filter housing is a pressurised AISI 304, 304L, 316, 316L or 316Ti filter body that holds one or more replaceable cartridges. With a capacity of 1–60 cartridges, it is for lines that need finer filtration than bag filters provide.

What Is a Stainless Steel Cartridge Filter Housing?
Because the body is made entirely of stainless steel, it is hygienic, chemically resistant and lasts for years; only the cartridge is replaced as a consumable. Because it can reach much lower micron ratings than bag filters, it is a reliable solution on precision lines that require high clarity and a low particle load. Depending on size, it can be made from 1-cartridge to 60-cartridge systems.

Filtration Architecture and Working Principle
Inlet & Distribution into the Body
Dirty process liquid fills the cartridge body through the inlet and spreads evenly over the outer surface of the cartridges. Flow moves along the cartridges in a balanced, controlled way.
Outside-In Cartridge Filtration
The liquid passes outside-in through the cartridge pores; particles above the specified micron rating are retained at the outer surface or in depth.
Central Clean Outlet
The liquid filtered through the cartridge’s central core passes without interruption from the collector nozzle at the base to the outlet line. Flow is delivered steadily and in a controlled way to the process line.
Advantages of the Stainless Steel Cartridge Filter Housing
- High Filtration Precision
- Particle retention precision down to 0.11 micron; ultra-clear filtration with membrane and pleated cartridges.
- Corrosion-Resistant Stainless Body
- AISI 304L / 316L / 316Ti body construction; long service life on chemical, saline and high-temperature lines.
- Safe Pressure Rating
- Standard 10 bar operating and 25 bar hydrostatic test pressure; higher PN classes up to 40 bar for special processes.
- Modular, Expandable Capacity
- From 1 to 60 cartridges; the number of cartridges and their length in inches can be increased to suit flow and contamination load.
- Zero-Bypass Sealing
- 215/222/226 O-ring sockets or a DOE compression rod reliably prevent bypass leakage.
- Hygienic, Food-Compatible Surface
- The buffed, smoothed inner surface reduces residue build-up and makes cleaning easier on hygienic lines such as food, beverages and pharmaceuticals.
- Quick Lid & Ergonomic Maintenance
- Bolted and swing-bolt lids; on large bodies, a davit lifting system with a handwheel allows easy change-outs by one person.
- Long Life & Low Operating Costs
- The heavy-duty stainless body lasts a lifetime; only the consumable cartridge is changed, or washable cartridges can be used.
Models and Flow Capacity
A wide range of models is offered, from single point-of-use housings to high-flow 60-cartridge multi-cartridge bodies, according to the flow rate and filtration area your process needs.
Single Cartridge Filter Housing
For single-cartridge, low-flow lines and point-of-use applications. Standard 10 bar operating and 25 bar test pressure; up to 40 bar for custom builds.

304L / 316L / 316Ti Options
304L for standard applications; 316L for corrosive/chlorinated environments; 316Ti body for high temperatures.
- Single Cartridge Filter Housing
- 1 cartridge, 10" equivalent; ~1 m³/h flow with standard cartridges, ~0.35 m³/h with pleated micro cartridges; 1" pipe connection.
- 3-Cartridge Filter Housing
- Capacity for 3 cartridges; 1½" pipe connection.

*Values are calculated on the basis of a 10″ cartridge equivalent and clean water (water-like viscosity): standard cartridge ~1 m³/h, pleated micro cartridge ~0.35 m³/h per 10″. 20″, 30″ and 40″ cartridges increase flow proportionally (2×, 3×, 4×). The final choice depends on micron rating, cartridge type and liquid viscosity; request a quote with your application details.

Single Cartridge Filter Housing Lid and Inlet/Outlet Types
The single cartridge filter housing is made in different types according to the lid connection and outlet direction. The following types can be chosen to suit your application and installation space:
Flanged Lid
Bolted flange lid; high durability for frequent, heavy use. Bottom or side outlet.
Flanged Lid with Swing Bolts
Flange lid with swing bolts (wing nuts); opens quickly without tools. Made on request. Bottom or side outlet.
Union Lid
Union-connected lid; practical dismantling and reassembly. Bottom or side outlet.
Clamp Lid
Clamp lid; the fastest cartridge changes, ideal for hygienic lines. Bottom or side outlet.
Inline Cartridge Filter Housing
Because the inlet and outlet are on the same line axis, it is ideal for tight installation spaces and direct connection to existing pipelines. Can be made with a flange, union or clamp lid.
Line Type Cartridge Filter Housing
Connects directly to the line quickly and easily; with the cartridge filter fitted inside, it brings the line into filtration without any extra installation arrangement.
Sealing: O-Ring vs. Gasket Cartridge
- O-Ring Cartridge Interface (215 / 222 / 226)
- The cartridge seats in the O-ring socket in the body; the O-ring provides excellent sealing through radial compression.
- Gasket Cartridge Interface (DOE - Double Open End)
- A specially developed compression rod compresses the gasket axially, giving full bypass protection at both open ends.

Material selection
When to choose it
On lines with a low to medium contamination load that require high clarity and low micron ratings (especially <5 µm), a cartridge filter housing gives much more precise and stable outlet quality than a bag.
When not to choose it
With a very heavy sediment load and high flow, cartridges clog quickly; in that case a bag filter housing or a pre-filter ahead of the cartridges is more economical.
Application and Selection Criteria
- Choosing the Right Lid and Mechanism
- Small and medium housings use a bolted lid as standard; on lines that need frequent opening, a swing-bolt or clamp lid can be fitted on request. On large, heavy multi-cartridge housings, a davit mechanism with a handwheel should be used for safety and operational ergonomics.
- Sealing Interface and Bypass Prevention
- For high-purity processes that require a critical micron rating, a 222 or 226 O-ring socket (226 locking) should be chosen; for general depth cartridges, a DOE interface with a compression rod is preferred.
- Differential Pressure (ΔP) Monitoring
- Always fit a pressure gauge or a differential pressure transmitter to the body inlet and outlet; change the cartridges when the differential pressure (ΔP) reaches 2.0 bar.
Cartridge Filter Housing Selection Technical Checklist
- Chemical Nature of the Fluid
- 316L if chlorine, acid or salt is present; 316Ti for high-temperature/weld-intensive lines; 304/304L for neutral water; usually 316 for food.
- Operating Temperature
- Determines the gasket choice: EPDM/silicone for hot water, Viton for aggressive chemical and oil lines.
- Required Cleanliness Level
- Choose the right cartridge micron rating (melt-blown, pleated, etc.) between 0.11 and 10,000 µm according to the clarity required.
- Process Flow Rate (m³/h)
- Flow determines the number of cartridges, cartridge length and pipe connection diameter.
- Contamination and Sediment Load
- With a high particle load, longer cartridges (30/40) and a multi-cartridge body multiply service life.
- Cartridge End Interface
- Choose an O-ring 215/222/226 interface (226 locking socket) or a DOE double-open-end interface with a compression rod, according to your current consumables.
- Connection & Lid Type
- Flange/muff/nipple depending on the line; a bolted lid is standard, a swing-bolt lid is fitted on request, and a davit with a handwheel is preferred for large, heavy housings.
- Maximum Line Pressure
- System operating pressure must be kept below the body's nominal class (standard 10 bar, test 25 bar, custom 40 bar).
- Food & Hygiene Standards
- For food and pharmaceutical contact, check for a buffed inner surface and a food-contact-compliant gasket material.
Points to Watch During Use
- Correct Placement & Seating
- The cartridge must be fully seated in the O-ring/gasket socket at the bottom of the body, leaving no bypass or air pocket.
- Differential Pressure (ΔP) Monitoring
- Change the cartridge when the differential pressure (ΔP) reaches 2.0 bar.
- Soft Start-Up
- Avoid sudden pressure surges (water hammer) at first start-up and open the air vent nozzle.
- O-Ring & Gasket Check
- Check O-rings and gaskets periodically; replace worn, hardened or cracked gaskets immediately.
- Housing Cleaning & Hygiene
- Clean the stainless steel body regularly to remove chemical deposits and maintain hygiene and corrosion resistance.
- Choosing the Right Consumables
- Use a cartridge type (spun/pleated/stainless), micron rating and gasket material suited to the process fluid and temperature.
