Advanced Depth Filtration for Industrial Applications
For industries requiring high-purity filtration with superior solids retention, the ErtelAlsop Pak® Lenticular Filter stands out as a premier solution. As a critical component in the processing of pharmaceuticals, food and beverage, chemicals, and botanical extracts, these lenticular cartridges offer an enclosed, sanitary, and efficient alternative to traditional plate and frame filtration methods.
At Purecowater, we understand the complexities of solid and liquid filtration. Whether you are scaling up production or looking to reduce product loss, the ErtelAlsop Pak® series provides the versatility and reliability needed for high-stakes processing.
What is a Lenticular Filter?
The ErtelAlsop Pak® cartridge is a depth filter module constructed from stacked lenticular cells. Each cell is composed of a pair of precision-cut depth filter media sheets (such as Micro-Media® or AlphaMedia®), sealed at the edges using a patented process. These cells are stacked around a central polypropylene core, resembling a series of double convex lenses.
This design maximizes surface area within a compact footprint, allowing for high flow rates and exceptional particulate retention. Unlike surface filters, these depth filter modules trap particles within the complex matrix of the media, making them ideal for clarification and polishing applications.

Key Features and Construction
The engineering behind the Pak® lenticular cartridges focuses on operational efficiency and product integrity. By utilizing an enclosed housing system, these filters eliminate the leakage often associated with plate and frame filters, ensuring a cleaner working environment and minimizing product loss.
- Versatile Configurations: Available in 12-inch and 16-inch diameters to fit standard housings.
- End Cap Options: Offered with Double O-Ring or Flat Gasket configurations for secure sealing.
- Robust Media: Manufactured with materials like cellulose and diatomaceous earth (DE) for effective sieving and adsorption.
- Sanitary Design: Supports single-pass or recirculating processes in a closed loop, reducing exposure to the environment.

Primary Applications
Due to their high solids loading capacity and Zeta potential, these filters are utilized across a wide spectrum of industries. ertelalsop.com
Botanical Extract Filtration
In the processing of botanical extracts, removing waxes, lipids, and fine particulates is essential for product clarity and quality. The Pak lenticular filters, particularly those impregnated with Diatomaceous Earth (DE), form a rigid cake that efficiently sieves out these impurities without affecting the odor or taste of the liquid.
Distilled Spirits and Beverages
For the distilled spirits industry, “chill haze” and particulate removal are critical. The depth media efficiently captures haze-forming proteins and particles, resulting in a polished, shelf-stable product.
Pharmaceutical & Cosmetics
Ensuring product safety and purity is paramount in life sciences. The enclosed nature of the lenticular housing prevents contamination, making it a preferred choice for pharmaceutical-grade filtration applications.
Why Switch to Lenticular Filtration?
Many facilities still rely on traditional plate and frame filters, which can be labor-intensive and prone to dripping. Transitioning to ErtelAlsop Pak® cartridges offers immediate operational benefits:
- Reduced Labor: Cartridges are easy to load and unload using the “Lock and Load” system.
- Zero Leakage: The sealed housing design prevents product loss and maintains a clean facility floor.
- Scalability: Modular design allows for easy scaling from pilot testing to full production.
