1078841 – Kit, E958, 4 Tank Sequential Filter

The AqMatic 1078841 Filter Nest Kit (E958) is a pre-configured valve nest assembly designed for 4-tank sequential filtration systems. It provides a fixed valve layout used to manage service and backwash cycles across four filter vessels operating in sequence.

In a 4-tank sequential configuration, tanks rotate through service and backwash stages in a controlled sequence, allowing continuous filtration while maintaining system efficiency and uptime. This setup is commonly used in higher-capacity filtration systems where flow demand and redundancy require more than two tanks operating in coordination.

As part of the Easy Nest platform, the E958 configuration removes the need to design valve groupings from individual components. It delivers a defined, repeatable assembly matched to multi-tank sequential filter systems, simplifying specification and ensuring consistent system performance.

The assembly is designed to integrate with external stagers and stager controls, which control valve actuation across service, backwash, and rinse cycles.

Compared to building systems from individual V42 diaphragm valves or K53 thermoplastic valves, this kit provides a standardized configuration that reduces installation variability and supports scalable system expansion.
