What is the Cartridge Filter Housing?
The cartridge filter housing is a device used in various fluid filtration applications to hold and secure filter cartridges. These housings are designed to enclose and support one or more filter cartridges, which are responsible for removing particles, impurities, or contaminants from liquids or gases passing through them.

BSPT
BSPT threads are tapered with a 55° angle, designed for pressure-tight seals, require sealing tapes, and are widely used in Europe, Asia, and Commonwealth countries
NPT
NPT threads, featuring a 60° taper for a tighter seal, are widely used in North America and among U.S. trade partners. Sealing tape is needed for a leak-proof connection
Tri-clamp ferrule
Tri-clamp ferrules are commonly used in sanitary applications due to their ease of quick opening and cleaning. The common standards are ISO 2852 and DIN 32676
Grooved coupling adapter
Victaulic grooved couplings can be used for quick connections, offering flexibility and reliability
How does it Work?
The cartridge filter housing directs liquid through a filter cartridge, where the filtration media efficiently captures and removes suspended particulates and contaminants from the liquid stream.
Filtration Process Overview:
The liquid first enters the filter housing through the inlet and flows around the filter cartridges inside. As the liquid passes through the cartridges, they act like a sieve, trapping dirt and unwanted particles on their outer surfaces. The now-clean liquid moves through the hollow center of the cartridges, then exits via the outlet to continue its journey to the next stage of production.
Specifications
What Materials are Used for Cartridge Filter Housings?
Stainless Steel
Stainless steel is the most commonly used material, with most products made from SS-304 and SS-316L. For special applications, SS-904L, SS-2205, and SS-2507 are available as options
Plastic
For corrosion-resistant applications, polypropylene is the most commonly used material. If high-temperature applications are required, PVDF is available as an option
FRP
For high-salinity applications, fiber-reinforced plastic (FRP) can be chosen, and its filter housing has the capacity to hold up to 54 high-flow filter cartridges
What are the Different Designs of Cartridge Filter Housings?
Industrial & commercial
Filter housings made of stainless steel are used for both commercial applications with low flow rates and industrial applications with high flow rates. They are applicable in areas such as industrial or municipal water treatment, chemical processing, petrochemicals, industrial manufacturing, and more
Sanitary
Stainless steel filter housings are designed with a sanitary construction that eliminates dead spots and facilitates easy cleaning. They are used in applications within the food and beverage industry, as well as in pharmaceuticals, biotechnology, and more
Corrosion-resistant
Filter housings made of plastic or FRP (Fiberglass Reinforced Plastic) are specifically designed for filtering acidic, alkaline, and high-salinity liquids
What Types of Filter Cartridges Can Be Used in Cartridge Filter Housings?
Depth Filter Cartridges
Melt-blown cartridges and string-wound cartridges with a 2.5" outer diameter can accommodate up to 120 filter cartridges. Available cartridge styles include DOE, 222, and 226
Pleated Membrane Cartridges
Cartridges with an outer diameter greater than 2.68" are typically placed inside sanitary filter housings and are of the 222 or 226 style
High Flow Pleated Cartridges
Filter housings of the same diameter, equipped with high flow cartridges, provide higher flow rates and can accommodate up to 24 cartridges
What Are the Common End Cap Types in Filter Cartridges for Cartridge Filter Housings?
DOE
The end cap of double-open-end (DOE) is the most common and economical type, often used in depth filter cartridges such as melt-blown and wound cartridges. Some specialized pleated membrane cartridges also use DOE with gaskets
222
Sealed with dual O-rings, the Push-In design allows for quick and reliable installation
226
Sealed with dual O-rings, the Spin-In design provides even more reliable installation
3M style
The 3M style high flow filter end caps come in two types: a large-diameter, 226-like Spin-In design (700 series) and a small-diameter, 222-like Push-In design (740 series)
Parker style
Parker style high flow filter end caps feature internal O-rings and are available with either a single O-ring or dual O-rings, both utilizing a Push-In design for installation
Pall style
Pall style high flow filter end caps resemble a filter bag design, where the sealing is achieved with an O-ring at the outermost ring on the top of the filter cartridge
What Types of Closure Devices are Used in Cartridge Filter Housings?

Sanitary Polished
Sanitary polishing of inside surface is ideal for food and pharmaceutical applications (Roughness ≤ 0.6 µm)
Halar (ECTFE) Coated
Halar is a cousin of Teflon (PTFE). The inside surface of the housing is coated to provide excellent corrosion and temperature resistance
H3: Pressure and Temperatures
H4: What are the Key Pressure Considerations for Bag Vessels?
Max Allowable Working Pressure (MAWP) is the maximum pressure level to which the equipment can be exposed. Design Pressure (DP) is the highest pressure level it should be exposed to under normal operating conditions.
Design Pressure (DP) is very close to MAWP. The Max Operating Pressure (MOP) is 75% of the DP. This means the maximum continuous pressure the filter can withstand must not exceed the MOP. The Operating Pressure (OP) is the pressure at which the filter can function properly, and it must not be less than 2 bar to ensure that the liquid is transported effectively into the filter.
For customized requirements, you need to provide the Max Operating Pressure (MOP), and Seadon can tailor the design accordingly.
H4: What are the Key Temperature Considerations for Bag Vessels?
Design Temperature (DT) refers to the maximum theoretical temperature that the filter vessel can withstand. The Max Operating Temperature (MOT) is the temperature the filter vessel can endure under continuous operation, typically set at 70% of the DT.
If there are customized temperature requirements, you can provide the Max Operating Temperature (MOT), and a customized design can be developed accordingly.
