For industrial applications requiring superior particle retention and high solids loading capacity, ErtelAlsop Pak® Lenticular Filters stand out as a premier solution. As a trusted distributor for top-tier filtration manufacturers, Purecowater is proud to offer these versatile depth filter cartridges designed to streamline your solid-liquid separation processes.
What are ErtelAlsop Pak Lenticular Filters?
The ErtelAlsop Pak® cartridge is a depth filter module constructed from stacked lenticular filter cells. Unlike traditional flat sheet filtration, this “lenticular” design (resembling a stack of double convex lenses) maximizes surface area within a compact footprint. These modules are engineered for use in a sealed housing, preventing liquid loss and protecting the filtrate from external contamination.
The core technology relies on ErtelAlsop’s renowned depth filter media—such as MicroMedia®, AlphaMedia®, and Zeta-Pak®—which are impregnated with filter aids like Diatomaceous Earth (DE) or high-purity cellulose. This structure creates a rigid, porous cake that effectively entraps particulate matter, waxes, and lipids while allowing for high flow rates.
Key Features and Benefits
- High Solids Loading: The depth media matrix allows for significant retention of solids before reaching differential pressure limits.
- Scalability: Available in 12-inch and 16-inch diameters with cell counts ranging from 5 to 18, making it easy to scale from lab testing to full production.
- Versatile Media Options: Compatible with various media grades (including activated carbon and pharmaceutical grade) to target specific contaminants.
- Leak-Free Design: Edge sealing via a patented polypropylene process ensures filter integrity.
- User-Friendly: Cartridges are easy to install and replace compared to traditional plate and frame filters.

Common Applications
Due to their ability to remove haze, lipids, and ultra-fine particles without affecting flavor or odor, these filters are heavily utilized in industries requiring high-purity outcomes.
- Botanical Extraction: Efficient removal of waxes and lipids from ethanol or hydrocarbon extracts.
- Food & Beverage: Haze removal in distilled spirits, syrups, and flavorings.
- Pharmaceuticals & Life Sciences: Clarification of cell cultures and removal of endotoxins using Zeta-potential positive media.
- Chemical Processing: Filtration of specialty chemicals and solvents where polypropylene supports offer chemical compatibility.
