Introduction to ErtelAlsop Pak® Lenticular Filters
For industrial applications requiring high-efficiency particle retention and superior solids loading capacity, ErtelAlsop Pak® Lenticular Filters stand out as a premier depth filtration solution. As a distributor for leading filtration brands, Purecowater provides these advanced modules to tackle complex solid and liquid filtration challenges.
The Lenticular Pak® cartridge, often referred to as a “module,” bridges the gap between traditional plate and frame filters and modern enclosed cartridge systems. By utilizing ertelalsop.com proprietary media in a stacked disc format, these filters offer a leak-free, operator-friendly, and cost-effective method for filtration in pharmaceutical, food & beverage, and chemical industries.
What is a Lenticular Filter?
The term “lenticular” refers to the shape of the filter cells, which resemble a stack of double convex lenses. Each module is constructed from varying numbers of filter cells—typically ranging from 5 to 18—stacked vertically.
Each cell consists of a pair of depth filter media sheets (such as MicroMedia®, AlphaMedia®, or MicroClear®) sealed at the edges using a patented polypropylene process.clearsolutionscorp.com. This design creates a rigorous matrix of fibers and particles that traps solids not just on the surface, but throughout the depth of the media.
Key Advantages
- Enclosed System: Unlike open plate and frame presses, lenticular housings are totally enclosed, preventing leakage and reducing exposure to the atmosphere.
- Scalability: Available in 12-inch and 16-inch diameters, allowing for easy scale-up from pilot to production.
- High Solids Loading: The complex fiber matrix allows for significant throughput before clogging.
- Rapid Changeout: The modular design allows for quick cartridge replacement, minimizing downtime compared to manually dressing a filter press.
