VPS wine and beverage grade cartridges have been designed to comply with all FDA requirements for the food and beverage industry. Polyethersulfone is low protein binding and therefore a good choice for fermented beverage filtrations. VPS cartridges are flushed with 17+ megohm-cm water to ensure that no manufacturing debris remains downstream to contaminate your product. This washing also ensures that all extractables which may affect the taste of the product are removed. Cartridges are custom configured to increase the surface area and give maximum throughputs. Each VPS is designed to handle cleaning and sanitization protocols well. Each cartridge module is individually tested to ensure integrity and is absolute at the rated pore size.
