GBPES-Series Wine and Beverage Grade Polyethersulfone

GBPES-Series High Purity Wine and Beverage Grade Polyethersulfone Filter Cartridges are optimized for the requirements of the wine and beverage industry.


GBPES-Series Overview

The polyethersulfone membrane offers high flux density and low protein binding and maintains the organoleptic characteristics of the treated product, making it an ideal choice for producing consumables. Cartridges are flushed with ultra-high purity water to achieve the most stringent requirements for extractable substances and are designed to tolerate repeated hot water sanitization and in situ steam sterilization cycles for maximum service life. Each element is integrity tested to ensure optimal performance and manufactured in a clean-room environment to maintain high standards of purity and cleanliness.
