FAQ

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

The DKF-S Series Composite Depth Lenticular Filters combines high-purity cellulose, inorganic filter aids, and resin to form a highly porous structure with three-dimensional channels. Designed for high-viscosity, colloidal, and multi-component process fluids, it delivers high dirt-holding capacity and retention efficiency through both physical interception and adsorption mechanisms.

Do you accept OEM/ODM for filtration products?

Yes, OEM/ODM is available. Send your detailed requirements to us.We are analyse it and provide professional solutions and proposals for your choice and help design appropriate filters.

What's the service life of the lenticular filters ?

The service life of the lenticular filters is affected by the use environment, frequency of use, the original media state, and the type of filter cartridge. Please provide us with more detailed information and our technical team will help evaluate it.

What are the industries that use LOONG’s lenticular filters?

LOONG’s filter cartridges find applications in a wide range of industries, including food and beverage, micro-electronics, life and science industry use.

What is the difference between surface filtration and depth filtration?

In surface filtration, a filter with a uniform pore design, traps contaminants that are larger than the pore size of the media. In depth filtration, the contaminants are trapped at multiple levels within the filter because of the tapered pore structure of the depth filters.

Are LOONG’s filter cartridges Food Contact and Pharmaceutical Compliant?

Yes, they mostly are.Most of our filter cartridges are certified according to FDA and GMP regulation EC 2023/2006.Please contact us to get the detailed certification.
