High-Performance Depth Filtration Solutions
For industries requiring rigorous purity standards and efficient solids removal, ErtelAlsop Pak Lenticular Filters represent the gold standard in depth filtration technology. As a distributor for premier filtration brands, Purecowater provides these advanced lenticular modules to tackle complex liquid filtration challenges in pharmaceutical, food and beverage, chemical, and utility applications.
The lenticular format, originally innovated by Alsop Engineering, offers a fully enclosed, leak-free alternative to traditional plate and frame filters. By combining high-capacity depth filter media with a user-friendly modular design, these filters ensure superior retention efficiency and ease of operation.
Key Advantages of ErtelAlsop Pak Filters
Lenticular filtration bridges the gap between traditional sheet filtration and cartridge filtration. The “Pak” design stacks 12 to 16 individual lenticular cells into a single module, providing a massive surface area in a compact footprint. This design offers several operational benefits:
- Closed System Design: Prevents product loss and protects operators from exposure to process fluids/fumes.
- Scalability: Existing plate and frame specifications can be easily translated to the lenticular format using the same media formulations (AlphaMedia™, MicroMedia®, etc.).
- Rapid Change-Out: Significant reduction in downtime compared to manually restacking plate and frame presses.
- High Solids Loading: Depth media structure allows for substantial contaminant holding capacity before clogging.
Product Spotlight: Zeta-Pak® Cartridges
The Zeta-Pak® is the workhorse of the ErtelAlsop line. These modules are versatile, utilizing MicroMedia® which incorporates cellulose, filter aids (like DE or Perlite), and resin binders. They are specifically engineered to provide a positive Zeta Potential, enhancing the adsorption of ultrafine particles, haze, and biological contaminants that are too small to be caught by mechanical straining alone.
Bio-Pak® for Pharmaceutical Applications
For critical applications in biotechnology and pharmaceuticals, the Bio-Pak® offers a double O-ring plug-in design. Unlike flat gasket models, the Bio-Pak eliminates stainless steel straps and utilizes a rigid polypropylene core. This ensures positive sealing and prevents bypass, critical for maintaining sterility and integrity in high-value batches.
Technical Specifications
Purecowater offers ErtelAlsop modules in various configurations to fit standard housings. Below are the typical specifications for the Zeta-Pak® and standard lenticular series.
| Feature | Specification details |
|---|---|
| Diameters | 12″ (30 cm) and 16″ (40 cm) |
| Micron Ratings | 0.25 to 15 Micron (Nominal) |
| End Cap Configurations | Flat Gasket, Double O-Ring (plug-in) |
| Media Types | Cellulose, Diatomaceous Earth (DE), Perlite, Carbon |
| Core Material | Polypropylene |

Housing Options: Vertical and Horizontal
To maximize the efficiency of the Pak cartridges, ErtelAlsop offers specialized housings available through Purecowater.
Horizontal Filter Housings: These units feature a “Lock and Load” system that simplifies loading. The horizontal orientation allows a single operator to load cartridges at waist height, eliminating the need for overhead hoists and reducing safety risks.
Sanitary Housings: Designed for pharma and biotech, these housings feature 316L stainless steel, high polish finishes, and sanitary fittings to ensure cleanability and compliance with industry standards.
Common Applications
- Pharmaceuticals: Clarification of cell cultures, removal of protein hazes using Bio-Pak modules.
- Botanical Extracts: Removal of waxes and lipids; efficient decolorization using carbon-impregnated media.
- Food & Beverage: Polishing of spirits, wines, and syrups; haze removal in distilled products.
- Utilities: Dielectric oil purification in electric utility transformers.
Get the Right Fit for Your Process
Selecting the correct media grade and housing configuration is vital for process efficiency. Whether you need to replace an aging plate and frame press or design a new filtration skid, Purecowater can help you integrate ErtelAlsop technologies seamlessly.
