Food and Beverage Grade Polyethersulfone

GFPES-Series Overview

GFPES-Series High Purity Food and Beverage Grade Polyethersulfone Filter Cartridges meet the most demanding requirement of the food and beverage industry. 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 the production of consumables. Cartridges are flushed with ultra-High Purity water to achieve the most stringent requirements for extractable substances. Designed to tolerate repeated hot water sanitization and in-situ steam sterilization cycles for maximum service life. Each element is integrity tested to assure optimal performance. Manufactured in a clean-room environment to maintain high standards of purity and cleanliness.
