High-Efficiency Depth Filtration for Industrial Applications
For industries requiring superior clarification and particulate removal, ErtelAlsop Pak® Lenticular Filters represent the gold standard in depth filtration technology. As a premium distributor, Purecowater provides these versatile filter modules to help facility operators tackle complex solid/liquid separation challenges, from botanical extraction to chemical processing.
These lenticular cartridges—often referred to as filter modules—combine the detailed retention capabilities of traditional depth filter sheets with the enclosed, leak-free convenience of cartridge housing. Whether you are filtering distilled spirits, pharmaceuticals, or industrial oils, the Pak® design ensures high solids loading and exceptional filtrate quality.
What is a Lenticular Pak® Filter?
The ErtelAlsop Pak® construct is essentially a pre-assembled stack of depth filter media cells. Unlike surface filters that only trap particles on the exterior, these depth filters utilize a thick, tortuous matrix to trap particles throughout the entire medium. This structure is typically composed of cellulose, filter aids (such as Diatomaceous Earth or Perlite), and resin binders.
The term “lenticular” refers to the lens-like shape of the stacked cells. This design maximizes surface area within a compact footprint, allowing for high flow rates and extended service life compared to standard cartridges.
| Feature | Benefit |
|---|---|
| Zeta Potential | Electrokinetic adsorption captures ultra-fine particles and haze (like lipids and waxes) smaller than the mechanical rating. |
| High Solids Capacity | The depth matrix absorbs a significant volume of contaminants before blinding, reducing changeout frequency. |
| Enclosed System | Modules fit inside sealed housings, preventing leakage and minimizing operator exposure to fluids. |
| Scalability | Available in 12-inch and 16-inch diameters with varying cell counts to match your batch size and flow rate. |
Core Applications and Industries
ErtelAlsop Pak® filters are engineered for versatility. They are heavily utilized in sectors where product purity is non-negotiable. clearsolutionscorp.com
- Botanical Extracts: Highly effective for winterization and the removal of waxes, lipids, and fine particulate from solvent-based extracts. The diatomaceous earth (DE) media aids in color correction and clarification.
- Food & Beverage: Used for clarifying syrups, distilled spirits, wines, and edible oils without affecting taste or odor.
- Pharmaceuticals & Cosmetics: Ensures purity in active pharmaceutical ingredients (APIs), perfumes, and lotions.
- Chemicals & Utilities: The AquaKv-Pak® variant is specifically designed for removing moisture and carbon from transformer oils and dielectric fluids. ertelalsop.com

Why Choose ErtelAlsop Media?
The secret to the performance of these filters lies in the media composition. The Zeta-Pak® series, for instance, provides a relatively high positive zeta potential. This allows the filter to attract negatively charged contaminants (such as bacteria and endotoxins) like a magnet, providing retention efficiency that exceeds simple mechanical sieving.
For applications involving moisture sensitivity, such as insulating oils in the power generation sector, the special formulation of the AquaKv-Pak® can maintain dielectric strength by absorbing dissolved water. ertelalsop.com
