Introduction to ErtelAlsop Pak® Lenticular Filters
For industries requiring high-efficiency depth filtration with the convenience of a cartridge system, ErtelAlsop Pak® Lenticular Filters provide an optimal solution. As a distributor and OEM for top-tier filtration manufacturers, Purecowater offers these advanced lenticular modules to tackle complex solid-liquid separation challenges. Whether you are scaling up from laboratory testing to full production or seeking an alternative to traditional plate and frame filters, the Pak® Lenticular series delivers reliability and performance.
The Lenticular Pak® (also known as a lenticular filter module) consists of stacked filter cells housed within a totally enclosed vessel. This design combines the superior filtration mechanics of depth media with the ease of use found in cartridge filtration systems.
Key Features and Benefits
The ErtelAlsop Pak® system is designed to overcome the limitations of standard flat sheet filtration. By sealing the edges of the filter media using a patented polypropylene molding process, the “wicking” issues often associated with open plate and frame presses are eliminated. The result is a clean, leak-free process suitable for high-purity applications.
- totally Enclosed System: Protects the product from environmental contamination and protects operators from exposure to process fluids.
- Scalability: Available in 12-inch and 16-inch diameters with varying cell counts, allowing for easy scale-up from pilot to commercial production.
- High Solids Loading: The depth media structure traps particles throughout the matrix, offering significantly higher dirt-holding capacity compared to surface filters.
- Rapid Change-Out: Modules can be replaced in minutes, reducing downtime compared to the labor-intensive cleaning of plate and frame presses.

Media Options and Performance
One of the primary advantages of the ErtelAlsop Pak® is the versatility of the filter media. The modules can be manufactured using various grades of depth filter sheets, ensuring chemical compatibility and specific filtration goals are met.
1. MicroMedia® (XL Options Available)
Incorporates cellulose, filter aids (such as Diatomaceous Earth or Perlite), and resin binders. This media allows for high flow rates and excellent retention of ultra-fine particles. It is ideal for haze removal and polishing.
2. AlphaMedia®
A pure cellulose media free from inorganic filter aids. It is frequently used where low extractables are required or where mineral content must be minimized.
3. MicroClear® (Activated Carbon)
Impregnated with activated carbon, these modules are designed for adsorption applications, such as decolorization, odor removal, and the removal of trace organic impurities without the mess of loose carbon powder.
Bio-Pak®: The Pharmaceutical Grade Solution
For critical applications in the pharmaceutical and biotech sectors, ErtelAlsop offers the Bio-Pak® configuration. Unlike standard flat-gasket modules, the Bio-Pak® utilizes a Double O-Ring plug-in style connector.
Bio-Pak® Advantages:
- Positive Sealing: The double O-ring seal ensures bypass-free filtration, critical for sterilizing-grade pre-filtration.
- Metal-Free Design: The center core is 100% polypropylene, eliminating potential metal ion contamination.
- Sanitary Geometry: Designed for easy cleaning and compatibility with sanitary housings.
Common Applications
Due to their robust design and range of media, Pak® Lenticular Filters are utilized across diverse industries.
| Industry | Typical Applications |
|---|---|
| Food & Beverage | Haze removal in distilled spirits, wine polishing, syrup clarification, and beer filtration. |
| Pharmaceuticals | API purification, post-fermentation clarification, and protection of downstream chromatography or membrane columns. |
| Botanical Extracts | Winterization (wax removal) and lipid removal from ethanol extracts. |
| Chemicals | Removal of catalysts, carbon treatment of process fluids, and purification of bulk chemicals. |
