Lenticular filter modules cartridges
Lenticular filters are modular depth filtration systems built from individual filter cells stacked around a central core inside a sealed housing.
- A large filtration area and high dirt-holding capacity support longer operating cycles while maintaining a low pressure drop.
- Available in cellulose, carbon, and synthetic media, these filters come in configurations that fit DOE, SOE, and sanitary housings.
- Available in micron ratings from 0.2 to 30 μm, these filters fit selected industry-standard housings and remove fine particles and sediment, with microbial retention depending on the filter grade and validated performance.
- Depth filtration solutions featuring depth filter sheets, filter paper sheets, and filter pads for reliable liquid clarification.
- Combine the high clarification capacity of plate-and-frame depth filter sheets with the ease of handling and reduced exposure of an enclosed cartridge system.
- For compatible Pall housings, these filters offer easy installation and consistent performance while helping minimise downtime.

How Does a Lenticular Filter Work?
Lenticular filters use an outside-in flow pattern. Unfiltered liquid enters the housing under pressure and surrounds the stacked filter cells. The pressure difference across each cell drives the liquid inward through the depth filter media.
The media contains a network of winding passages, often called tortuous paths. As liquid moves through these passages, suspended particles can be captured at different depths within the media.
The filtered liquid then flows into the central core, which collects the filtrate from each cell and directs it to the lenticular housings outlet.

Frequently Asked Questions
Can you reuse a lenticular filter?
A pleated filter cartridge is a filtration element made from folded filter media that increases surface area within a compact design. It provides efficient particle removal, high dirt-holding capacity, and low pressure drop.
When should you replace a lenticular filter?
Replace a lenticular filter when it reaches the manufacturer’s differential pressure limit (typically between 1.5 to 2.5 bar (22-36 psi)), can no longer maintain the required flow, or produces filtrate that falls outside your quality specification. If the module supports regeneration, replace it when an approved cleaning cycle fails to restore acceptable performance.
Can Cofilters lenticular filters be backwashed?
Backwashing should be used only on Cofilters lenticular modules explicitly approved for reverse flow. Ask Cofilters to confirm compatibility for your exact module code, media grade, and housing configuration. Before backwashing, obtain the applicable pressure and temperature limits and confirm whether the module requires support plates.
How do I select the right grade of lenticular filter module?
Start with the liquid’s solids load and the clarity you need. Choose a coarser grade for bulk solids removal or a finer grade for polishing. Test the grade on a representative sample to confirm filtrate clarity, throughput, and pressure drop before committing to full-scale production.
