Evolution Aqua Nexus 320+ Automatic Cleaning Kit – Gravity
Automatic Cleaning Upgrade for Gravity Fed Nexus 320+ Filters
The Evolution Aqua Nexus 320+ Automatic Cleaning Kit – Gravity automates the full cleaning cycle of compatible gravity fed Nexus 320 filtration systems. Instead of manually operating slide valves, adjusting supporting equipment and opening waste outlets, the system controls each stage through a programmable control unit.
This kit can be installed on Nexus 320 filters manufactured from 2006 onwards. The newer Nexus 320+ and Nexus 320+ Ti models are supplied auto ready as standard, meaning they already include the required fittings for straightforward installation of the automatic cleaning kit.
Once installed, you can programme the cleaning cycle to operate at fixed intervals. Alternatively, you can activate a cycle manually when required. Therefore, the system provides both convenience and flexibility while maintaining consistent mechanical performance.
How the Gravity Automatic Cleaning Cycle Works
The kit manages a structured cleaning sequence that flushes the Eazy chamber efficiently and safely.
Firstly, the timer activates the cleaning cycle. The control box immediately switches off the circulation pump, allowing water levels inside the filter to stabilise.
Next, the automatic inlet slide plate closes. At the same time, the system redirects air from the biological chamber into the Eazy chamber. This increased air agitation lifts and separates trapped solids from the K1 Micro media. As a result, debris releases quickly and evenly.
The automatic waste valve then opens and discharges contaminated water to waste. After the purge stage completes, the inlet slide plate reopens to allow a final rinse. Subsequently, the waste valve closes and the system redirects air back to the biological chamber.
Finally, the circulation pump restarts and the Nexus 320+ returns to normal filtration mode. Because the kit controls every stage automatically, it delivers consistent cleaning performance and reduces the risk of operator error.
Compatibility and Installation
This gravity version is suitable for Nexus 320 filters manufactured from 2006 onwards. However, it is not compatible with pump fed installations.
The Nexus 320+ models are supplied auto ready for direct installation of this kit. Earlier Nexus 320 models require the appropriate fittings to be installed during upgrade which come included.
This gravity version is not suitable for pump fed Nexus systems. A separate automatic kit is available for pump fed configurations.
The cleaning interval is factory set to every 3 days. Nevertheless, you can adjust the frequency to match stocking density, feeding rates and seasonal waste production. During periods of heavy feeding, more frequent cleaning cycles may improve mechanical efficiency.
By automating the Eazy chamber cleaning process, the Nexus 320+ Automatic Cleaning Kit – Gravity maintains reliable filtration performance while significantly reducing routine maintenance.
