S Series Composite Depth Lenticular Filters – For High-Viscosity & Colloidal Fluid Filtration


The DKF-S Series Composite Depth Lenticular Filters are engineered with high-purity cellulose, inorganic filter aids, and resin, creating a highly porous three-dimensional filtration structure. Designed for high-viscosity, colloidal, and multi-component process fluids, the filters provide excellent dirt-holding capacity and reliable particle retention through a combination of physical interception and adsorption mechanisms.

Do you provide OEM/ODM services for filtration products?

Yes, OEM/ODM services are available. Please send us your detailed requirements, and our technical team will evaluate your needs and provide professional filtration solutions and proposals. We can also assist in designing suitable filter configurations based on your application.


What is the service life of lenticular filters?

The service life of lenticular filters depends on factors such as the operating environment, frequency of use, initial fluid condition, and filter type. Please provide more information about your application, and our technical team can help evaluate the expected service life.


Which industries use LOONG's lenticular filters?

LOONG's lenticular filters are used across a variety of industries, including food and beverage, microelectronics, life sciences, and other industrial applications.


What is the difference between surface filtration and depth filtration?

Surface filtration captures contaminants primarily on the surface of the filter media, particularly particles larger than the effective pore size. Depth filtration, by contrast, captures contaminants throughout the internal structure of the media, where particles are retained at different depths within the filter.


Are LOONG's filter cartridges compliant with food-contact and pharmaceutical requirements?

Yes. Most of our filter cartridges are manufactured to meet relevant FDA and pharmaceutical requirements. Selected products are also produced in accordance with GMP requirements and EC 2023/2006 for food-contact materials. Please contact us for detailed product-specific compliance and certification information.
