At Purecowater, we understand that efficient liquid filtration is critical for industries ranging from pharmaceuticals to food and beverage processing. As a distributor and OEM for top-tier filtration solutions, we are proud to feature ErtelAlsop Pak® Lenticular Filter Cartridges. These depth filter modules offer a robust, sealed alternative to traditional plate and frame filters, providing superior particle retention and ease of operation.
What are ErtelAlsop Pak® Lenticular Filters?
ErtelAlsop Pak® depth filter cartridges—often referred to as lenticular modules—are designed to provide high-performance liquid filtration in a totally enclosed system. Each module acts as a stack of “lenticular” (lens-shaped) cells. These cells are composed of pairs of premium depth filter media sheets, sealed at the edges using a patented process.
This design combines the filtration mechanics of traditional depth filter sheets with the convenience of a cartridge format. The result is a system that prevents leakage, reduces product loss, and simplifies change-outs compared to standard plate and frame presses [ertelalsop.com].
Why Choose Lenticular Technology?
Lenticular filtration is the preferred choice for applications requiring high solids loading capacity and the removal of ultra-fine particles. The enclosed housing design ensures a sanitary environment, protecting the product from external contamination and protecting operators from exposure to the fluid.
Key Benefits:
- Leak-Free Operation: Unlike plate and frame filters that can drip or leak, lenticular cartridges are housed in sealed vessels [ertelalsop.com].
- Rapid Change-Out: Modules can be replaced in a fraction of the time required to dress a filter press, minimizing downtime.
- Scalability: With sizes ranging from laboratory scale to production scale (12″ and 16″ diameters), processes can be easily scaled up.
- Media Versatility: Available in various media grades, including cellulose, diatomaceous earth (DE), and activated carbon.
Media Configurations and Series
ErtelAlsop offers several series of Pak® cartridges to address specific filtration challenges, from removing haze in spirits to purifying dielectric oils.
| Series Media | Composition | Primary Applications |
|---|---|---|
| Zeta-Pak® (Micro-Media®) | Cellulose, Diatomaceous Earth (DE), Wet Strength Resin | The “workhorse” of the line. Excellent for haze removal, botanical extracts, and general fine filtration. High zeta potential for ultra-fine particle retention [store.clearsolutionscorp.com]. |
| Disc-Pak® (AlphaMedia™) | 100% Cellulose (No DE or Perlite) | Ideal for light to medium viscosity liquids where no DE functionality is required. Used in dielectric oils, syrups, and perfumes to preserve active ingredients [clearsolutionscorp.com]. |
| MicroClear® | Immobilized Activated Carbon | Color, odor, and flavor correction without the mess of bulk carbon powder [ertelalsop.com]. |

Industrial Applications
The versatility of the ErtelAlsop Pak® system makes it suitable for a wide array of markets. Whether you are clarifying botanical extracts or polishing industrial oils, there is a media grade available.
- Pharmaceuticals: Sterile filtration (Bio-Pak®) and active ingredient protection.
- Food & Beverage: Clarification of syrups, distilled spirits, and wines.
- Botanical Extracts: High flow rates and efficient removal of waxes and lipids using DE-impregnated media [store.clearsolutionscorp.com].
- Chemicals & Utilities: Filtration of lubricating oils, coolants, and water purification.
Compatible Filter Housings
To utilize these cartridges, a compatible lenticular filter housing is required. ErtelAlsop manufactures both vertical and horizontal housing orientation options:
- Vertical Housings: Standard footprint for many industrial applications.
- Horizontal Housings: Feature a “Lock and Load” system for single-person loading and unloading, eliminating the need for overhead hoists [ertelalsop.com].
