ErtelAlsop Pak® Lenticular Filters: High-Efficiency Depth Filtration

For industries requiring high-efficiency solids removal and liquid clarification, ErtelAlsop Pak® Lenticular Filters represent a premier solution in depth filtration technology. As a distributor for top-tier filtration manufacturers, Purecowater provides these advanced lenticular modules to help facilities tackle complex liquid filtration challenges, offering a leak-free, user-friendly alternative to traditional methods.

What are ErtelAlsop Pak® Lenticular Filters?

ErtelAlsop Pak® depth filter cartridges—often referred to as lenticular modules—are comprised of stacked filter cells designed for superior particle retention and high solids loading capacity. The term “lenticular” refers to the shape of the assembled unit, which resembles a stack of double convex lenses.

Each filter cell is constructed from a pair of depth filter media sheets (such as MicroMedia®, AlphaMedia®, or MicroClear®). The edges of these sheets are sealed using a patented process with polypropylene, ensuring a robust structure that prevents bypass. These cells are then stacked on a central core to form a cohesive cartridge module.

Manufactured in standard 12-inch (30.5 cm) and 16-inch (40.6 cm) diameters, these modules are compatible with a wide range of housings and are designed to seamlessly scale from laboratory testing to full-scale production [ertelalsop.com](https://ertelalsop.com/lenticular-pak-cartridges/).

Key Features and Benefits

The Pak® cartridge system is designed to overcome the limitations of traditional plate and frame filters. By utilizing a totally enclosed housing design, these filters eliminate edge leakage and external contamination, making them ideal for pharmaceutical, food, and beverage applications.

  • High Efficient Particle Retention: Nominal retention ratings range from 0.25 to 15 microns, suitable for applications ranging from coarse clarification to sterile filtration pre-treatment.
  • High Solids Loading: The complex matrix of fibers in the depth media allows for significant contaminant holding capacity before a pressure drop occurs.
  • User-Friendly Design: The modules allow for rapid change-outs, drastically reducing labor and downtime compared to manual plate and frame presses.
  • Versatile Configurations: Available in flat gasket or double O-ring end caps to fit various filter housings [store.clearsolutionscorp.com](https://store.clearsolutionscorp.com/products/pak-lenticular-filter).

Applications

ErtelAlsop Lenticular Filters are versatile and are widely used across various sectors due to their ability to handle different chemical compatibilities and viscosity ranges.

  • Pharmaceuticals: Clarification of active ingredients and sterile pre-filtration.
  • Food & Beverage: Haze removal in spirits, syrups, and botanical extracts.
  • Chemicals: Filtration of solvents, lubricating oils, and process fluids.
  • Cosmetics: Purification of perfumes and essential oils.
  • Botanical Extracts: Effective removal of waxes and lipids using DE-impregnated media [store.clearsolutionscorp.com](https://store.clearsolutionscorp.com/products/pak-lenticular-filter).

Why Upgrade to Lenticular Filtration?

Historically, many facilities relied on plate and frame filter presses. While effective, these systems often suffer from dripping, exposure to the environment, and labor-intensive media change-outs. The ErtelAlsop Pak® system offers a modern upgrade:

  • Enclosed System: Prevents product loss and maintains a sanitary environment.
  • Scalability: “Lock and Load” horizontal housing designs allow for single-person operation and easy scaling [ertelalsop.com](https://ertelalsop.com/depth-filtration-equipment/lenticular-filter-housings/horizontal-filter-housing/).
  • Consistency: The pre-assembled modules ensure consistent performance batch-to-batch, unlike manually packed filter sheets.

Whether you need to remove particulate from dielectric oils or clarify a high-value botanical extract, the ErtelAlsop Pak® series provides reliability and efficiency.
