Introduction to ErtelAlsop Pak® Lenticular Filters
For industries facing complex liquid filtration challenges, the ErtelAlsop Pak® Lenticular Filter represents a premium solution for depth filtration. As a trusted distributor and OEM, Purecowater provides access to these high-performance filter modules, which are designed to offer the benefits of traditional plate and frame filtration within a totally enclosed, leak-proof system.
The Pak® depth filter cartridges (also known as modules) are engineered for critical applications ranging from pharmaceutical processing to botanical extraction and food and beverage production. By utilizing a stacked disk design, these filters maximize surface area and solid-loading capacity while minimizing footprint and maintenance time.
How Lenticular Technology Works
The term “lenticular” refers to the shape of the stacked filter cells, which resemble double convex lenses. Each module consists of multiple filter cells stacked vertically.
A single module typically contains between 5 to 18 cells. Each cell is constructed from a pair of depth filter media sheets (such as MicroMedia® or AlphaMedia®) with edges sealed using a patented polypropylene process. This design forces liquid through the media matrix, trapping particulates within the depth of the sheet, rather than just on the surface.
According to ertelalsop.com, this configuration allows specifications from existing plate and frame processes to be easily translated to the lenticular format, offering a distinct advantage: a closed system that prevents leakage and protects operators from exposure to the product.

Media Configurations
Purecowater offers ErtelAlsop Pak® cartridges with several distinct media types to suit specific chemical compatibility and filtration goals:
- AlphaMedia™ (Cellulose): A 100% cellulose media ideal for light to medium viscosity liquids. It contains no resins, binders, or inorganic filter aids (like DE or Perlite), making it perfect for applications where active ingredients must remain unaltered, such as in dielectric oils or certain cosmetic products.
- MicroMedia® (Impregnated): Incorporates filter aids like Diatomaceous Earth (DE) or Perlite within the cellulose matrix. This creates a rigid, porous structure capable of high-efficiency particle retention and haze removal. It is frequently used in botanical extracts to remove waxes and lipids clearsolutionscorp.com.
- MicroClear® (Carbon): Features activated carbon immobilized within the media sheet, allowing for color and odor correction without the mess of handling loose carbon powder.
Compatible Filter Housings
The performance of the Pak® cartridges is optimized when paired with ErtelAlsop’s specialized housings. These housings are available in both vertical and horizontal orientations.
Horizontal “Lock and Load” Housings
The horizontal housing design is a modern alternative to vertical bells. It allows for single-operator loading and unloading at chest height, eliminating the need for overhead hoists. The “Lock and Load” system uses Teflon guides to slide cartridges easily into place, significantly reducing changeout downtime compared to plate and frame filters ertelalsop.com.
Applications
These cartridges are suited for a wide variety of industries due to their scalable nature and sanitary design options:
- Pharmaceuticals: for sterile filtration and particulate removal.
- Food & Beverage: widely used for distilled spirits, syrups, and wine clarification.
- Botanical Extracts: excellent for lipid and wax removal using DE-impregnated media.
- Chemicals & Utilities: including insulating oil reconditioning and water purification.
- Cosmetics: for perfumes and lotions requiring high clarity.
