ISO Certified Horizontal High Flow Filter Housing and 70 inch High Flow Filter Cartridge For Industrial Application
High Flow Filtration with Fewer Cartridges
Pullner High Flow Filter Housing is designed for applications where standard 2.5-inch cartridges would require a large housing and frequent cartridge replacement.
The housing uses large-diameter pleated filter cartridges with a high filtration area. One high flow cartridge can replace multiple conventional cartridges, reducing the number of elements inside the housing and making installation and maintenance easier.
Single-cartridge and multi-cartridge housings are available for different flow requirements. Vertical designs save installation space, while horizontal designs make long cartridges easier to remove.
The housing can be matched with Pullner high flow cartridges and cartridges designed as replacements for common Pall, 3M, Parker and Pentair high flow filter styles.

Why Use a High Flow Filter Housing?
- Fewer Filter Cartridges: The large-diameter pleated cartridge provides more filtration area than a standard cartridge
- Smaller Housing: Reducing the number of cartridges allows the filter vessel to be smaller and simplifies the internal structure
- Faster Cartridge Replacement: Operators have fewer elements to remove and install, reducing maintenance time
- Lower Disposal Volume: Fewer used cartridges mean less handling, storage and disposal work
- Easier Internal Cleaning: The simplified cartridge arrangement leaves more space inside the housing for inspection and cleaning
- Suitable for System Upgrades: Ideal when existing multi-cartridge systems have limited flow capacity or require excessive maintenance
Typical Applications
Pullner high flow filter housings are commonly used in:
- Seawater desalination pretreatment
- Reverse osmosis system pre-filtration
- Power plant condensate filtration
- Cooling water and circulating water
- Municipal and industrial water treatment
The system is normally installed before RO membranes, pumps, heat exchangers, spray nozzles and other equipment that requires protection from particles and suspended solids.
High Flow Cartridge Options
Pullner can provide different high flow cartridge structures according to the existing housing or project requirements.
Common options include:
- Single-open-end cartridges
- Double-open-end cartridges
- Inside-to-outside flow cartridges
- Outside-to-inside flow cartridges
Before production, we confirm the cartridge outside diameter, length, sealing structure, O-ring size and flow direction to ensure correct installation.

Fast Technical Response
Our team can quickly review flow rate, pressure, temperature, liquid type and filtration accuracy and prepare a suitable configuration.
Drawing Confirmation
A technical drawing can be provided before production to confirm the main dimensions, nozzle positions and cartridge arrangement.
Support for Trial and Project Orders
We support single replacement housings, trial units, OEM orders and complete project filtration systems.
Frequently Asked Questions
What is the difference between a high flow filter and a standard cartridge filter?
A high flow filter uses a large-diameter pleated cartridge with a larger filtration area. It can handle more liquid with fewer cartridges than a standard 2.5-inch cartridge system.
How many high flow cartridges are required?
The quantity depends on the total flow rate, liquid viscosity, filtration rating, contaminant level and required cartridge service life.
What is the flow rate of one cartridge?
A 60-inch high flow cartridge can handle up to approximately 110 m³/h under suitable clean-water conditions. The actual flow rate should be confirmed according to the application.
Are vertical and horizontal housings available?
Yes. Vertical housings require less floor space. Horizontal housings are often selected for multi-cartridge systems because long cartridges are easier to remove.
Can the housing use Pall or 3M-style cartridges?
Yes. Pullner can design the housing for common Pall, 3M, Parker and Pentair-style high flow cartridges. The exact cartridge model and dimensions should be confirmed before production.
Can the housing replace an existing unit?
Yes. Please provide the existing housing drawing, cartridge model, nameplate information or site measurements. We will check the connection and installation dimensions.
Which material should I choose?
SS304 is commonly used for general industrial water. SS316L is more suitable for seawater, corrosive liquids and higher-purity applications. Carbon steel can be considered for cost-sensitive, non-corrosive applications.
What information is required for selection?
Please provide: Liquid name, required flow rate, filtration rating, operating pressure, operating temperature, existing cartridge model, inlet and outlet size, preferred housing material, vertical or horizontal installation, and required design standard.
