Introduction to ErtelAlsop Pak® Lenticular Filters
For industries requiring superior liquid clarification and high-efficiency particulate removal, the ErtelAlsop Pak® Lenticular Filter represents the evolution of depth filtration technology. Available through Purecowater, these modules combine the high capacity of depth filter sheets with the ease of use of a cartridge design.
The Pak® modules are essentially a pre-assembled stack of depth filter sheets, sealed in a lenticular (lens-shaped) configuration. This design provides a closed filtration system that eliminates the drips, leakage, and exposure to air often associated with traditional plate and frame filters. Whether you are filtering botanical extracts, distilled spirits, or industrial chemicals, the Pak® Lenticular series offers a scalable and sanitary solution.
How Lenticular Depth Filtration Works
Unlike surface filtration, which catches particles only on the top layer, depth filtration utilizes a thick matrix of fibers to trap particles throughout the media. The ErtelAlsop Pak® cartridges utilize media types such as Micro-Media® and AlphaMedia™, which are often impregnated with filter aids like Diatomaceous Earth (DE) or Perlite.
A critical feature of these filters is their Zeta Potential. The media is formulated with a wet strength resin that imparts a positive electrokinetic charge. This charge attracts negatively charged contaminants (like haze, bacteria, and fine particulates) that are smaller than the filter’s physical pore size, significantly enhancing filtration efficiency clearsolutionscorp.com.
Key Specifications and Features
The Pak® cartridges are designed to fit into standard lenticular housings and are available in various configurations to suit specific flow rates and retention requirements.

Primary Applications
Due to the versatility of the media (cellulose, DE, Activated Carbon), these filters are used across a wide spectrum of industries.
1. Botanical Extract Filtration
In the processing of hemp and cannabis extracts, ErtelAlsop Pak modules are a “workhorse.” They are particularly effective for winterization and wax removal. The depth media, often containing Diatomaceous Earth, efficiently sieves out lipids and waxes while the high surface area allows for rapid flow rates, even with viscous fluids clearsolutionscorp.com.
2. Food & Beverage
- Distilled Spirits: Removal of haze and fatty acids (chill haze) to polish the final product.
- Wine & Beer: Clarification and microbial reduction without stripping flavor.
- Syrups & Soft Drinks: Particulate removal for product consistency.
3. Industrial & Utilities
The AquaKv-Pak® variant is designed specifically for the filtration of dielectric fluids, such as transformer oils. It removes moisture and carbon particulates to maintain the insulating properties of the oil ertelalsop.com.
Why Choose Lenticular Modules Over Plate & Frame?
While traditional plate and frame filters are effective, lenticular modules offer modern operational advantages:
- Zero Leakage: The modules are housed in a sealed vessel, preventing product loss and messy spills.
- Reduced Oxidation: The closed system prevents the liquid from contacting the atmosphere, preserving quality in oxygen-sensitive products like wine or essential oils.
- Rapid Changout: Swapping out a spent module takes minutes compared to the labor-intensive process of restacking a plate and frame press.
- Scalability: The same media used in lab-scale discs is used in these production modules, allowing for linear scalability.
