Advanced Depth Filtration Solutions
In the world of industrial liquid filtration, the transition from open plate and frame systems to enclosed depth filtration modules represents a significant leap in operational efficiency and safety. ErtelAlsop Pak® Lenticular Filters are at the forefront of this technology, offering a robust solution for applications ranging from pharmaceutical processing to botanical extraction.
At Purecowater, we distribute premium filtration solutions including the ErtelAlsop Pak® line to help you solve complex solid-liquid separation challenges. Whether you need high solid loading capacity or ultra-fine particle retention, these lenticular cartridges provide the versatility required for critical processes.
What are Pak® Lenticular Cartridges?
ErtelAlsop Pak® depth filter cartridges (also known as modules) are totally enclosed filtration units designed to serve as an alternative to traditional filter presses. Each “Pak” consists of a stack of lenticular filter cells ranging from 5 to 18 cells high.
The construction is unique: individual filter cells are created by sealing pairs of depth filter media sheets (such as MicroMedia® or AlphaMedia®) at the edges using a patented polypropylene process. These cells are then stacked to resemble double convex lenses—hence the term “lenticular.” This design maximizes surface area within a compact footprint, allowing for high flow rates and exceptional throughput.
Key Features and Benefits
Why do operators switch to ErtelAlsop Pak® cartridges? The primary advantage is the enclosed system design. Unlike open plate and frame filters, lenticular housings prevent leakage and limit exposure to the liquid, making them ideal for hazardous chemicals, high-value pharmaceuticals, and hygienic food and beverage applications.
- High Solids Loading: The complex matrix of fibers in the depth media allows for significant retention of solids before the filter blinds.
- Scalability: Designs are easily scalable from laboratory testing to full-scale production.
- Efficiency: Zeta potential in the media enhances the capture of ultra-fine particles beyond simple mechanical sieving.
- Ease of Use: Cartridges can be changed out in a fraction of the time required to dress a plate and frame press.

Product Variants: Zeta-Pak® vs. Bio-Pak®
To ensure chemical compatibility and performance across different industries, ErtelAlsop offers distinct product lines within the Pak® family:
- Zeta-Pak®: The “workhorse” of the industrial line. These modules are versatile and provide excellent retention efficiencies for general chemical, cosmetic, and food applications. [clearsolutionscorp.com]
- Bio-Pak®: Designed for critical applications, the Bio-Pak® series (often utilized in the pharmaceutical grade housings) features a Double O-Ring configuration for positive sealing and eliminates stainless steel straps in favor of a rigid polypropylene core. This ensures the highest level of sanitary integrity. [ertelalsop.com]
- MicroClear®: Incorporates activated carbon for applications requiring color or odor removal without the mess of bulk carbon.
Target Applications
The adaptability of ErtelAlsop Pak® Lenticular Filters makes them suitable for a wide range of markets:
- Botanical Extracts: Perfect for removing waxes and lipids (winterization) due to the DE filter aid and high flow capability.
- Food & Beverage: Polishing distilled spirits, syrups, and edible oils.
- Pharmaceuticals: Clarification of cell cultures and removal of protein precipitates.
- Utilities: Insulating oil reconditioning in the electric utility sector.
Compatible Housings
These cartridges are designed to fit into ErtelAlsop’s extensive line of lenticular housings. Options include:
- Vertical Housings: Standard industrial or sanitary designs.
- Horizontal Housings: The “Lock and Load” design allows for easier change-outs at waist height, reducing labor and downtime. [ertelalsop.com]
