Industrial High-Flow Filter Housing: Multi-Round Cartridge Systems for Large-Scale Liquid Filtration

Industrial filter housing selection becomes significantly more complex as flow requirements scale — and for high-volume liquid filtration duties, a multi-round cartridge housing often provides a more practical solution than multiple single-vessel arrangements.

As flow requirements increase, using multiple individual housings can add more pipework, connections and cartridge change-out points. Multi-round high-flow cartridge housings provide a more consolidated option. By holding several large-diameter cartridges within one vessel, they can support higher flow rates while helping simplify the overall filtration layout.

A multi-round high-flow cartridge housing is a single filtration vessel designed to hold multiple large-diameter cartridges in a horizontal configuration. Unlike standard single-stack housings, multi-round designs consolidate filtration capacity, supporting higher flow rates while reducing the number of separate housings, pipework connections and cartridge change-out points required in an industrial system.

Scaling Industrial Filtration Systems Without Adding Complexity

Increasing filtration capacity is not only a matter of adding more housings. The system also needs to suit the available space, operating pressure, temperature, contaminant loading and required filtration level.

Maintenance should also be considered early. More housings can mean more cartridges, seals and connections to access during servicing, which can increase the time required for cartridge change-outs and add more points to manage during operation.

For high-flow duties, the aim is to increase capacity while keeping the system practical to access, operate and maintain.

The 66 Series Multi-Round High-Flow Filter Housing

The 66 Series HFC Multi Round cartridge housing is designed for use with SupaPleat HFC and SupaSpun HFC cartridges in large-scale liquid filtration applications. Installed horizontally, it accommodates three, four, five or seven large-diameter cartridges in 40-inch or 60-inch lengths.

Large-diameter cartridges provide a high filtration surface area within each vessel. This supports higher flow rates and can reduce the time required for cartridge change-outs compared with standard-diameter arrangements.

 

66 Series HFC Multi Round Specifications

Key housing features include:

• Horizontal configuration for cartridge access
• Hinged and bolted closure
• 316L stainless steel construction for corrosion-resistant industrial filtration environments
• Built-in support stand
• Upstream and downstream vent and drain ports
• A choice of connection types and sizes
• Full housing customisation service available
• Options for integration into complete industrial water filtration system packages

The housing range supports applications across water treatment, beverage production, chemical processing and pharmaceutical manufacturing. Full configuration details, dimensions and operating limits are available in the technical datasheet here.

The housing must also be matched with the right cartridge. Selection depends on the liquid being treated, flow rate, contaminant loading, operating conditions and required removal rating. BHF can review suitable high-flow cartridge options, including SupaPleat HFC and SupaSpun HFC cartridges, based on the application requirements.

Matching the System to the Process

A high-flow housing is only one part of the filtration system. The cartridges, pipework and supporting components must also work together under the site’s operating conditions.

As Devan Wesley, National Sales Manager – ANZ at BHF, explains:

“High-flow filtration is not only about increasing capacity. The housing, cartridge arrangement, and supporting system need to be selected around the process conditions, maintenance requirements, and available space.”

BHF can review:

• Required flow rate and filtration duty
• Operating pressure and temperature
• Cartridge media and removal rating
• Materials and connection standards
• Available installation space
• Cartridge access and change-out requirements
• Skid-mounted system requirements

Where required, the housing can be incorporated into a skid-mounted package, bringing the vessel, pipework and supporting equipment together in one system.

Overall, multi-round high-flow housings offer a practical way to manage larger liquid flow rates within a single vessel. Their cartridge capacity and horizontal design help consolidate the filtration arrangement while maintaining access for operation and maintenance.
