Advanced Depth Filtration for Critical Applications
For industries requiring high-purity liquid filtration, ErtelAlsop Pak® Lenticular Filters represent the gold standard in depth filtration technology. As a distributor for premier filtration brands, Purecowater provides these versatile modules to tackle rigorous solid and liquid separation challenges. Whether you are upgrading from plate and frame presses or designing a new sanitary process, the Pak® cartridge offers a scalable, leak-free solution.
What is a Lenticular Filter?
The ErtelAlsop Pak® is a depth filter module comprised of stacked lenticular cells. Each cell consists of a pair of filter media sheets (such as MicroMedia® or AlphaMedia®) with edges sealed by a patented polypropylene process. This assembly resembles a stack of double convex lenses—hence the term "lenticular."
Unlike traditional surface filters, these cartridges utilize a complex matrix of fibers to trap particles throughout the depth of the media, providing exceptional solids loading capacity and high retention efficiency [ertelalsop.com](https://ertelalsop.com/lenticular-pak-cartridges/).
Key Features and Benefits
The Pak® design transforms the filtration process by offering a totally enclosed, operator-friendly system. Key advantages include:
- High Solids Loading: The depth media matrix allows for significant particulate retention before blinding, ensuring longer service life.
- Enhanced Particle Retention: Utilizing Zeta Potential, the media carries a localized positive charge that electro-kinetically attracts negatively charged contaminants like bacteria and endotoxins [store.clearsolutionscorp.com](https://store.clearsolutionscorp.com/products/pak-lenticular-filter).
- Zero Leakage: When used with compatible housings, the enclosed design eliminates edge leakage often associated with plate and frame filters.
- Scalability: Available in 12-inch and 16-inch diameters with over 300 precision dies to fit virtually any housing.
