The Evolution Aqua Nexus Automatic Gravity 220 is an automated cleaning system upgrade for gravity fed installations of Nexus 220+ and old Nexus 220/210 filters manufactured after 2006.

The Nexus Automatic Gravity 220 includes a control box which connects up to an automated waste valve, air pump control box and an automatic inlet slide plate (for gravity fed models only). Once installed and connected to your pond pump and mains power the system will carry out cleaning cycles at timed intervals or when pressing the manual clean button.

Physically turning ball valves and manually switching pumps on and off will now be a thing of the past thanks to the Nexus Automatic System. All of the key processes that form the cleaning cycle are now controlled automatically with this easy to install kit.
