High-Performance Depth Filtration Solutions
In the world of industrial liquid processing, the ErtelAlsop Pak® Lenticular Filters stand out as a premier solution for depth filtration. Designed to combine the filtration efficiency of traditional plate and frame systems with the convenience of a contained cartridge format, these modules filter liquids through a depth media matrix to remove particulates, haze, and other impurities.
As a distributor for top-tier filtration manufacturers, Purecowater provides these versatile lenticular cartridges to industries ranging from pharmaceuticals to food and beverage. This guide explores the specifications, benefits, and applications of the ErtelAlsop Pak® series.
What Are Lenticular Pak® Cartridges?
ErtelAlsop Pak® cartridges, often referred to as lenticular modules, act as a modern evoltuion of flat filter sheets. The design consists of stacked filter cells—typically 5 to 18 cells per unit—assembled around a central core. Each cell is made of a pair of depth filter sheets (such as MicroMedia® or AlphaMedia®) with sealed edges. The resulting shape resembles a double convex lens, which gives the “lenticular” technology its name.
This configuration creates a totally enclosed, pressurized system when placed inside a housing, eliminating the leakage and exposure often associated with open plate and frame presses.
Key Advantages
- Leak-Free Operation: The enclosed design prevents product loss and exposure to the environment, making it ideal for hazardous or high-value fluids.
- Scalability: Modules are available in 12-inch (30.5 cm) and 16-inch (40.6 cm) diameters to fit various batch sizes.
- High Solids Loading: The depth media structure traps particles throughout the thickness of the pad, not just on the surface, offering superior retention capacity.
- Rapid Change-Out: Swapping out a cartridge takes a fraction of the time required to dress a plate and frame filter press.
Technical Specifications
The versatility of the Pak® Lenticular series lies in its wide range of configurations. Whether your process requires the removal of coarse particulates or sub-micron haze, there is a specification to match.

Filter Media Types
The core performance of the Pak® cartridge enters through its media. ErtelAlsop offers several proprietary media formulations to target specific contaminants:
- MicroMedia®: A cellulose-based media often impregnated with filter aids like Diatomaceous Earth (DE) or Perlite. It offers high flow rates and excellent retention for fine particles. [store.clearsolutionscorp.com]
- AlphaMedia®: A pure cellulose media used where inorganic filter aids are not desired.
- MicroClear®: Activated carbon-impregnated media used for adsorption applications, such as removing color, odor, or flavor taints.
Applications and Industries
Due to their enclosed nature and sanitary design possibilities, ErtelAlsop Lenticular Filters are widely used across multiple sectors.
Pharmaceuticals & Cosmetics
In high-purity environments, the risk of contamination must be zero. The Pak® cartridges are available in pharmaceutical-grade options to ensure compliance while removing lipids, waxes, and fine haze from syrups, serums, and fragrances.
Food & Beverage
From distilled spirits to botanical extracts, these filters excel at polishing liquids. They are particularly known for “chill haze” removal in brown spirits and the removal of waxes in botanical extractions.
Chemical & Industrial
The robust construction allows for the filtration of oils, inks, and paints. The ability to stack modules (1, 2, 3, or 4 high) in a housing allows for high throughput in relatively small footprints.
Housing Compatibility
The modules are designed to fit into ErtelAlsop Lenticular Filter Housings, available in both vertical and horizontal orientations. The unique “Lock and Load” design of the horizontal housings simplifies the loading process, reducing operator strain and change-out downtime.
