About us
Kefilbao Filter Technology (Suzhou) Co., Ltd. is a high-tech company specializing in bag filters and folding filter elements, integrating product research and development, production, and sales.

SPBRCS Bio-Burden Reduction Grade Filer Polyethersulfone capsule filters are 100% integrity tested; ensures bio-burden and small particle removal in a wide range of food& beverage, biological liquids, and intermediate bulk pharmaceutical fluids. The SPBRCS-Series is constructed of a single-layer hydrophilic asymmetric polyethersulfone membrane. It offers broad chemical compatibility, high flow rates at low pressure drops, and low extractables.
Polyethersulfone is particularly suited for the filtration of products that contain substances that adsorb to the media,
The lower binding characteristics of polyethersulfone make it a good choice for filtration of valuable protein solutions such as vaccines and biologicals.
