High-Efficiency Depth Filtration for Industrial Applications
At Purecowater, we specialize in providing top-tier industrial filtration solutions. Among our premier offerings for liquid clarification and solids removal are the ErtelAlsop Pak® Lenticular Filters. Designed for versatility and high performance, these depth filter modules are the industry standard for applications requiring superior retention of ultra-fine particles, including botanical extracts, pharmaceuticals, and food/beverage processing.
This guide breaks down the specifications, operational advantages, and applications of the ErtelAlsop Lenticular Pak® cartridges to help you determine the best configuration for your filtration needs.
Quick Summary: The ErtelAlsop Pak® is a depth filter cartridge consisting of stacked lenticular cells. It offers a closed system alternative to plate and frame filters, preventing leakage and reducing exposure to the environment.
What is a Lenticular Pak® Filter?
The Lenticular Pak® is a depth filtration module constructed from multiple filter cells stacked on a specialized core. Each cell is comprised of two discs of depth filter media (such as Micro-Media® or AlphaMedia®) with their edges sealed using a patented polypropylene process. This design resembles a stack of double convex lenses while providing a high surface area in a compact footprint.
These filters create a rigid, porous structure that effectively sieves out particulate matter as liquid passes through the media. The depth aspect allows for high solids loading capacity, trapping particles throughout the thickness of the media rather than just on the surface.
Key Features & Benefits
- Closed Filtration System: Fits inside sanitary or industrial housings, preventing product loss and protecting operators from fumes or hazardous fluids.
- High Zeta Potential: Utilizing Micro-Media® impregnated with Diatomaceous Earth (DE), these filters provide excellent electro-kinetic adsorption for ultra-fine haze removal.
- Scalability: Available in 12-inch and 16-inch diameters with varying cell counts (up to 16+ cells) to meet specific flow rate and batch size requirements.
- User-Friendly Design: Easier to change out compared to loose sheet plate and frame presses, significantly reducing labor and downtime.

Specialized Applications
While versatile enough for general industrial use, the ErtelAlsop Pak® excels in specific high-demand sectors:
Botanical Extraction
For the cannabis and botanical extraction industry, removing waxes, lipids, and fine particulate is critical for product quality. The Pak® filter, particularly those using DE-impregnated media, offers the necessary depth to capture these impurities without affecting the odor or taste of the extract. The polypropylene construction ensures compatibility with common solvents like ethanol.
Chemical & Pharmaceutical
From API solvent filtration to catalyst removal (such as carbon or platinum recovery), lenticular modules offer a safe, hermetically sealed environment ideal for handling valuable or hazardous chemical streams.
Food & Beverage
Ideal for the varying turbidity loads found in distilled spirits, syrups, and edible oils, ensuring a polished final product with high clarity.
Available Media Configurations
Choosing the right media is essential for performance:
- Micro-Media®: Cellulose formulations containing filter aids like Diatomaceous Earth (DE) or Perlite. Best for high-efficiency haze removal.
- AlphaMedia®: 100% Cellulose media. Ideal for applications where DE is not permitted.
- MicroClear®: Activated carbon-impregnated media. Used for decolorization and odor removal without dealing with loose carbon powder.
