The innovative Nexus Automatic System enables Nexus Filter owners to benefit from a fully automated cleaning cycle on their multi award winning Nexus filtration systems. Available in 3 different models to suit Nexus Pump Fed set ups as well as Nexus 220 and Nexus 320 Gravity Fed installations. Physically turning ball valves and manually switching pumps on and off will become 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. The Nexus Automatic System is factory set to perform the cleaning process every 3 days, but the frequency of cleaning can be altered from once an hour too once every 10 days depending on the cleaning frequency which suits you and your pond. The cleaning cycle can also be performed manually, by triggering the manual clean button on the control box.
