The LL Series uses lenticular depth filtration rather than loose diatomite media. This helps simplify operation, reduce media handling, and provide a cleaner closed-system filtration process. It is designed to deliver consistent clarification performance while supporting easier change-out and lower residual product hold-up.

The bottom inlet/outlet configuration helps promote a more uniform flow path through the filter stack and can reduce product retention inside the housing. This is especially useful for batch processing where product recovery, cleaning efficiency, and minimizing residual liquid between batches are important.

Selection should be based on required batch volume, flow rate, number and size of lenticular filter stacks, process fluid, operating temperature, pressure, connection type, and seal material. The LL Series can be configured with different stack quantities, inlet/outlet sizes, and seal options according to system requirements.

The listed maximum operating temperature is below 90°C, and the maximum differential pressure is 0.5 MPa. Actual allowable conditions should also consider housing material, seal material, filter stack specification, fluid properties, and process configuration. Final operating limits should be confirmed for the selected setup.

Replacement should be based on filtration performance rather than a fixed service interval. Typical indicators include increasing differential pressure, reduced flow rate, longer batch processing time, or deterioration in filtrate clarity. Actual service life depends on solids loading, fluid viscosity, selected filter grade, batch volume, and operating conditions.
