Advanced Replacement for
Plate and Frame Filters
The LLP Series Lenticular Filter Housing offers an advanced alternative to
plate and frame filters, using a modular stack of precision filter discs for
efficient solid-liquid separation. Its enclosed design prevents leaks and
contamination, while quick-change membranes cut downtime by 70%.
Built with sanitary 316L stainless steel and automated controls, it delivers
reliable performance for food, pharmaceutical, and industrial applications.
The housing is mounted on a stainless steel mobile trolley, creating a compact, ready-to-use filtration system that can be easily moved between production lines.
Benefit: Save installation space and improve operational flexibility.
Designed with a high-performance sealing system to ensure leak-free operation and protect your product from contamination.
Benefit: Minimize product loss and ensure safe, hygienic filtration.
Supplied with an integrated sanitary pump, pressure gauge and piping, providing a complete turnkey filtration solution.
Benefit: Reduce installation time and start production faster.
Equipped with industrial lockable wheels for smooth movement and secure positioning during operation.
Benefit: Easily relocate the filtration system while maintaining stability and safety.

What is the LLP Series lenticular filter housing mainly used for?
The LLP Series is designed for clarification and solid-liquid separation in food and beverage, pharmaceutical, fine chemical, and electronic process applications. It provides a closed lenticular filtration system that can be used as an alternative to traditional plate-and-frame filtration where cleaner operation, easier change-out, and reduced product exposure are required.
How does the LLP Series differ from a traditional plate-and-frame filter?
The LLP Series uses enclosed lenticular filter modules instead of exposed filter sheets or plates. This helps reduce leakage risk, product exposure, and manual handling while simplifying filter replacement. Its multi-disc configuration also provides a compact filtration area, making it suitable for processes where space efficiency and operational cleanliness are important.
How do I choose the right LLP Series housing configuration?
Selection should be based on required flow rate, batch volume, number and diameter of filter stacks, process fluid, operating temperature, pressure, inlet/outlet connection, and seal material. Available configurations include different stack quantities, housing materials, seal options, and connection sizes, so the complete process conditions should be provided before final selection.
Is the LLP Series suitable for mobile or flexible production lines?
Yes. The LLP Series can be supplied on a stainless steel mobile skid with lockable casters, allowing the system to be moved between different production lines when required. Configurations with an integrated sanitary pump, piping, and pressure monitoring can further simplify installation and reduce setup time.
What operating limits should be considered for the LLP Series?
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 selection, installed filter stack, fluid properties, and system configuration. Final operating limits should be confirmed for the selected assembly.
How do I know when the lenticular filter modules should be replaced?
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, filter grade, batch volume, and operating conditions.
