For industries requiring high-purity filtration with efficient solids handling, ErtelAlsop Pak® Lenticular Filters represent a premier solution. As a distributor for top-tier filtration technologies, Purecowater provides these advanced depth filter modules to tackle complex solid and liquid separation challenges. Whether for pharmaceutical applications, botanical extracts, or food and beverage processing, the Pak® Lenticular series offers the reliability of depth filtration in a user-friendly, enclosed format.
What are ErtelAlsop Pak® Lenticular Filters?
The ErtelAlsop Pak® cartridge (also known as a lenticular module) is a depth filtration system designed to replace traditional plate and frame filters. Instead of open frames, this technology stacks multiple lenticular filter cells vertically within a totally enclosed housing. This design minimizes leakage, reduces exposure to the atmosphere, and significantly speeds up change-out times.
Each module consists of stacked filter cells—typically ranging from 5 to 18 cells—manufactured from various grades of depth filter media. The edges of these media sheets are sealed using a patented process (often polypropylene), creating a coherent unit that resembles a stack of double convex lenses [ertelalsop.com].
Key Features and Benefits
Closed-System Design
Unlike open plate and frame presses, Pak® lenticular cartridges operate inside sealed housings. This is critical for applications involving hazardous fluids, volatile spirits, or high-purity pharmaceutical products where environmental exposure must be eliminated [ertelalsop.com].
Versatile Media Configurations
The Pak® cartridges utilizes ErtelAlsop’s renowned filter media families, providing a wide spectrum of retention ratings and chemical compatibility:
| Media Series | Composition | Primary Applications |
|---|---|---|
| MicroMedia® (Zeta-Pak®) | Cellulose + Diatomaceous Earth (DE) / Perlite | Haze removal, polishing, oils, botanical extracts. Validated options available. |
| AlphaMedia™ (Disc-Pak®) | 100% Cellulose | Dielectric oils, perfumes, applications sensitive to DE or silica. |
| MicroClear® | Activated Carbon impregnated | Color correction, odor removal, decolorization. |
High Solids Loading
The complex matrix of fibers and filter aids (like DE) within the media creates a tortuous path for fluids. This depth allows the filter to retain particles throughout the thickness of the media, not just on the surface, offering high solids holding capacity and efficient removal of hazes [store.clearsolutionscorp.com].

Applications
The versatility of the Pak® Lenticular Filters makes them suitable for a diverse range of industries.
- Pharmaceuticals & Bio-Processing: Ideal for post-fermentation clarification and removal of lipids or waxes. The Bio-Pak® configuration offers a double O-ring design for positive sealing, critical in high-purity environments [ertelalsop.com].
- Botanical Extracts: Used extensively for winterization and dewaxing. The Media efficiently removes particulate matter, waxes, and lipids while maintaing high flow rates [store.clearsolutionscorp.com].
- Food & Beverage: Excellent for polishing distilled spirits, syrups, and sugar solutions.
- Chemicals & Industrial: Suitable for dielectric oils, lubricating oils, and chemical filtration where particulate retention is paramount [clearsolutionscorp.com].
