Premium Depth Filtration Solutions with ErtelAlsop Pak® Lenticular Cartridges
For industries requiring high-purity liquid filtration with ease of operation, ErtelAlsop Pak® Lenticular Filters represent the gold standard in depth filtration technology. As a distributor for top-tier filtration manufacturers, Purecowater provides these advanced modules to help facilities tackle complex solid and liquid separation challenges.
The Pak® Lenticular Cartridge combines the superior filtration mechanics of traditional depth filter sheets with the convenience of an enclosed modular design. Whether you are processing botanical extracts, pharmaceuticals, or distilled spirits, these filters offer reliable particle retention, high solids loading capacity, and a leak-free operational environment.
What is a Lenticular Filter?
A lenticular filter module consists of multiple depth filter sheets stacked in a vertical orientation. Each pair of sheets is sealed at the edges to form a “cell” that resembles a double convex lens (hence the term “lenticular”). These cells are stacked on a central core and compressed to form a single cartridge unit.
This design allows for a large surface area within a compact footprint. Fluid flows from the outside of the module, passes through the filter media, and exits through the center core. The result is a highly efficient filtration process that captures particles through both mechanical sieving and electrokinetic adsorption.
Key Advantages:
- Closed System: Eliminates leakage and exposure to the atmosphere, crucial for volatile solvents or hygienic applications.
- Rapid Changeout: Modules can be replaced in minutes compared to the hours often required for plate and frame filter presses.
- Scalability: Available in 12-inch and 16-inch diameters to fit various housing sizes.
Core Technology: Zeta-Pak® and Micro-Media®
ErtelAlsop utilizes proprietary media formulations to enhance filtration performance. The Zeta-Pak® series is particularly notable for its use of Zeta Potential. The media is formulated with wet-strength resins that create a positive electrokinetic charge, allowing the filter to attract and hold negatively charged contaminants (like bacteria or endotoxins) that are smaller than the physical pore size of the media.
The media often incorporates high-quality Diatomaceous Earth (DE) or Perlite, pre-impregnated into the cellulose matrix. This eliminates the need for messy loose filter aids and ensures immediate clarity in the filtrate.

Primary Applications
The versatility of the Pak® design makes it a “workhorse” across various sectors. The combination of high flow rates and superior retention makes it ideal for:
- Botanical Extracts: Excellent for removing waxes and lipids from ethanol extractions (winterization) due to the DE content and sieving structure.
- Distilled Spirits: Used for chill haze removal and polishing to ensure a visually bright product without stripping flavor.
- Pharmaceuticals (API): Suitable for solvent filtration and catalyst removal where product purity is non-negotiable.
- Food & Beverage: Clarification of syrups, juices, and vinegars.
- Cosmetics: Filtration of perfumes and essential oils.
