Introduction to ErtelAlsop Pak® Lenticular Filters
In the world of industrial liquid filtration, efficiency, reliability, and ease of operation are paramount. ErtelAlsop Pak® Lenticular Filters represent a sophisticated solution for depth filtration, combining the benefits of traditional plate and frame technology with the convenience of a totally enclosed cartridge system. These lenticular modules are designed to handle a wide range of applications, from pharmaceuticals to food and beverage processing, offering a leak-free and user-friendly alternative to open filtration systems.
As a distributor for top-tier filtration manufacturers, Purecowater is proud to offer these high-performance modules. Whether you are dealing with botanical extracts, distilled spirits, or industrial process fluids, the Pak® cartridges provide exceptional particle retention and solids loading capacity.
What is a Lenticular Filter?
A lenticular filter module, often referred to as a “Pak,” consists of stacked filter cells. Each cell is made of a pair of depth filter media sheets—such as MicroMedia® or AlphaMedia®—sealed at the edges using a patented process. The resulting stack resembles a series of double convex lenses, which is where the term “lenticular” comes from. This design allows for a large surface area within a compact footprint, maximizing flow rates and dirt-holding capacity.
According to ertelalsop.com, these modules serve as a direct replacement for flat sheet filters used in plate and frame presses. By moving to a lenticular format, operators can eliminate the drip and leakage often associated with plate and frame filters, ensuring a cleaner and safer working environment.
Key Features and Benefits
- Enclosed System: The cartridges are housed in a sealed vessel, preventing liquid loss and exposure to the environment. This is crucial for high-value fluids and hazardous applications.
- High Solids Loading: The depth media structure traps particles throughout the thickness of the pad, not just on the surface, allowing for higher solids holding capacity compared to pleat filters.
- Scalability: With over 300 precision dies available, these filters can be scaled from laboratory testing to full-scale production.
- Versatile Media Options: Available in pharmaceutical grade, water removal, and various micron ratings ranging from 0.25 to 15 microns.

Popular Media Configurations
ErtelAlsop offers several specific product lines within the Pak® family to target different filtration challenges:
Zeta-Pak®
The Zeta-Pak® is the workhorse of the series. Incorporating filter aids like Diatomaceous Earth (DE) or Perlite into the cellulose matrix, it provides superior retention efficiencies. It is highly effective for applications requiring the removal of haze or fine particulate, such as in botanical extracts where it efficiently removes waxes and lipids store.clearsolutionscorp.com.
Disc-Pak®
For applications where adding mineral filter aids is not desired, the Disc-Pak® utilizes 100% cellulose AlphaMedia. This is ideal for dielectric oils, perfumes, and syrups where preserving the purity of active ingredients without DE interaction is critical clearsolutionscorp.com.
Applications
The versatility of ErtelAlsop lenticular filters makes them suitable for a broad spectrum of industries:
- Food & Beverage: Filtration of spirits, syrups, wines, and juices.
- Pharmaceuticals: Clarification of active pharmaceutical ingredients (APIs).
- Cosmetics: Purification of perfumes and lotions.
- Chemicals: Filtration of process fluids, inks, and paints.
- Botanical Extracts: Removal of plant waxes and lipids in ethanol extraction processes.
Housing Solutions
To complement the cartridges, ErtelAlsop provides specialized **Lenticular Filter Housings**. These are available in both vertical and horizontal orientations. The horizontal housing is particularly noted for its ergonomics, allowing for easier loading and unloading of cartridges (“Lock and Load” design) at waist height, eliminating the need for overhead hoists ertelalsop.com.
