The Manitowoc K-00337 is a pre-filter cartridge for AR-PRE or Arctic Pure systems, acting as the first line of defense against sediment. With a 5-micron rating, it captures larger particulates to protect downstream filters and components. The cartridge operates efficiently under 25–125 PSI pressure and 1.5 GPM flow rate. It prevents clogging of the primary cartridge, extending system life. Compatible with standard Arctic Pure heads for easy installation. Ideal for environments with high sediment content. Reduces downtime and maintenance frequency. Ensures consistent ice machine reliability and water quality.
