Advanced Depth Filtration Solutions for Industrial & Sanitary Applications
At Purecowater, we specialize in providing top-tier filtration technologies for complex liquid processing challenges. As a distributor and OEM partner, we are proud to offer ErtelAlsop Pak® Lenticular Filters. These depth filter cartridges represent a significant evolution in filtration technology, combining the efficiency of depth media with the convenience of a closed, modular system.
Whether you are upgrading from traditional plate and frame presses or designing a new filtration skid for pharmaceuticals, chemicals, or food and beverage applications, the ErtelAlsop Pak® provides a scalable and leak-free solution.
What is the ErtelAlsop Pak®?
The ErtelAlsop Pak® is a lenticular depth filter cartridge (also known as a module). It is constructed from multiple “cells” stacked vertically. Each cell consists of two discs of depth filter media sealed together at the edges using an injection-molded polypropylene process. These cells are then stacked on a central core and compressed to form a single, robust cartridge unit.
This design functions like a pre-assembled plate and frame filter pack but fits inside a sealed housing. The result is a system that eliminates the leakage, exposure, and labor intensity associated with traditional filter presses [ertelalsop.com].
Key Advantages over Plate & Frame Filters
- Zero Leakage: The fully enclosed housing prevents product loss and maintains a sanitary environment.
- Rapid Change-out: Modules can be replaced in minutes rather than hours.
- Scalability: Available in 12-inch and 16-inch diameters with varying cell counts to match flow rates.
- Media Versatility: Utilizes the same high-quality MicroMedia®, AlphaMedia®, and MicroClear® media found in filter sheets.
Filter Media Options and Technology
One of the strongest features of the ErtelAlsop Pak® line is the wide range of media formulations available to target specific contaminants. The complex matrix of fibers and filter aids (such as Diatomaceous Earth or Perlite) creates a tortuous path for fluid, offering both mechanical sieving and electrokinetic adsorption (Zeta Potential).
| Media Series | Composition | Primary Application |
|---|---|---|
| MicroMedia® | Cellulose, Perlite, DE | High solids loading, haze removal, general clarification. Ideal for botanical extracts [store.clearsolutionscorp.com]. |
| AlphaMedia® | Pure Cellulose | Applications requiring no mineral/silica content. |
| MicroClear® | Activated Carbon & Cellulose | Color correction, odor removal, and impurity adsorption without loose carbon dust. |
Technical Specifications
The flexibility of the Pak® system allows it to be tailored to specific process parameters. Below are the standard specifications for the cartridges available through Purecowater.
| Feature | Specification Details |
|---|---|
| Diameters Available | 12-inch (30.5 cm) and 16-inch (40.6 cm) |
| Micron Retention Ratings | 0.25 µm to 15 µm (Nominal) |
| Number of Cells | Standard stacks range from 5 to 18 cells (16 is common) |
| Gasket Materials | EPDM, Buna-N, Viton, Silicone, PTFE Encapsulated |
| End Cap Configurations | Flat Gasket (Standard Industrial) or Double O-Ring (Bio-Pak® Sanitary) |
| Core Material | Polypropylene or Stainless Steel (depending on model) |
Note: For pharmaceutical applications requiring high sanitary standards, the Bio-Pak® configuration utilizes a double O-ring seal to ensure positive seating and eliminate bypass [ertelalsop.com].
Common Industries and Applications
The ErtelAlsop Pak® provides high-efficiency particle retention and solid loading capacity, making it a “workhorse” across various industries:
- Pharmaceuticals & Biotech: API filtration, cell debris removal, and final polishing.
- Food & Beverage: Haze removal in spirits, wine polishing, and syrup clarification.
- Botanical Extracts: Removal of waxes and lipids from extractions (e.g., ethanol or CO2 extraction processes) where high flow and fine particulate removal are critical.
- Chemical Processing: Catalyst recovery and solvent purification.
- Utilities: Dielectric oil filtration in electric utility housings [ertelalsop.com].
Why Partner with Purecowater?
Selecting the correct comprehensive filtration system requires more than just picking a part number. At Purecowater, we help you determine the correct micron rating, media compatibility, and housing configuration (vertical or horizontal) for your specific process stream.
Whether you need a single 12-inch module for a pilot lab or a multi-housing skid for full-scale production, our team can engineer the solution that fits your throughput requirements.
