Advanced Depth Filtration for Industrial Reliability
For industries requiring high-performance solid and liquid separation, ErtelAlsop Pak® Lenticular Filters represent the evolution of depth filtration technology. These cartridges, also known as lenticular modules, offer a totally enclosed, sanitary, and user-friendly alternative to traditional plate and frame filter presses. Designed to handle diverse applications from pharmaceutical processing to botanical extraction, the Pak® series combines precision particle retention with high solids loading capacity.
As a distributor for premium filtration solutions, Purecowater provides these versatile modules to help facilities upgrade their filtration efficiency while minimizing product loss and labor costs. Contact Us to discuss the right media configuration for your process.
What Are Lenticular Pak® Filters?
The ErtelAlsop Pak® cartridge is constructed from stacked lenticular filter cells. Each cell consists of a pair of depth filter media sheets (such as MicroMedia® or AlphaMedia®) with edges sealed using a patented polypropylene process. This assembly creates a double convex lens shape—hence the term “lenticular.”
These modules are typically available in 12-inch (30.5 cm) and 16-inch (40.6 cm) diameters, containing anywhere from 5 to 18 stacked cells depending on the surface area required [ertelalsop.com](https://ertelalsop.com/lenticular-pak-cartridges/).
Key Benefits Over Traditional Methods
While traditional plate and frame filters are effective, they often suffer from leakage, exposure to the environment, and labor-intensive changeouts. The Pak® Lenticular format solves these issues by housing the media inside a sealed vessel.
- Leak-Free Design: The enclosed system prevents external contamination and product leakage, crucial for expensive or hazardous fluids.
- Rapid Changeout: Modules can be replaced in minutes rather than the hours required to dress a filter press.
- Scalability: Existing plate and frame specifications can be easily translated to the lenticular format using the same media grades.
- High Solids Loading: The complex fiber matrix provides excellent throughput and particle retention.
Media Configurations: Zeta-Pak® vs. Disc-Pak®
Selecting the correct media composition is vital for optimizing your filtration process. ErtelAlsop offers distinct series tailored to specific viscosity and retention needs [clearsolutionscorp.com](https://www.clearsolutionscorp.com/product/disc-pak-lenticular-filter).
| Feature | Zeta-Pak® Series | Disc-Pak® Series |
|---|---|---|
| Composition | Cellulose impregnated with Diatomaceous Earth (DE) or Perlite. | 100% Cellulose (AlphaMedia). No inorganic filter aids. |
| Best Application | Haze removal, botanical extracts, fluid polishing, removal of waxes/lipids. | Dielectric oils, coolants, syrups, and applications sensitive to DE. |
| Key Characteristic | Positive Zeta Potential for enhanced ultra-fine particle retention. | Ideal for light to medium viscosity liquids where active ingredients must be preserved. |
Technical Specifications
