Nexus Eazy 200

The Nexus Eazy 200  is Evolution Aqua's exciting new filter system incorporating the industry proven Kaldnes moving bed coupled with the innovative Eazy mechanical filter. The Nexus Eazy 200 provides outstanding water clarity and quality, pump or gravity fed. It is extremely Eazy and "clean" to maintain, minimal running costs, requires no service parts such as foam, is designed and built to last for life as well as offering unrivalled price performance.

How it works:
The Nexus Eazy 200 incorporates is a stainless steel vessel containing a volume of static K1 media which is located within the centre chamber of the Nexus Eazy 200. Water enters the centre chamber and then enters the Nexus Eazy Eazy via slots in the lower half of the unit. This results in a downward flow causing many of the larger solids to settle out prior to entering the Nexus Eazy 200. The size of the slots will not allow large mechanical waste to enter the cylinder thus acting as a first stage mechanical filtration. The water then passes through the static K1 media utilizing up and side flow and this process causes the fine solids to become entrapped. The mechanically clean water then passes to the outside chamber of the Nexus Eazy 200 where the Kaldnes moving bed is located for biological treatment prior to being returned to the pond.

Maintenance
The Nexus Eazy 200 is extremely easy and pleasurable to clean. The water pump is switched off and an air valve is operated which diverts air from the main Nexus eazy 200 air ring into the base of the Nexus Eazy. This causes the K1 media to be agitated and cleaned vigorously. As this happens the captured particles are flushed out into the central chamber of the Nexus Eazy 200, allowing you to see the amount of waste that has been filtered out. Once the K1 media has been agitated for a sufficient period, the water in the central chamber is flushed to waste using the purge valve provided at the base of the Nexus Eazy 200. Once clean, the air flow is re-directed back to the main air ring and the system started again. The whole process from start to finish can take less than two minutes.

The Eazy features Evolution Aqua's new solids removal system utilising static Kaldnes. The Kaldnes is retained in a 316 stainless steel enclosure and has been proven to trap incredibly small waste particles, without disrupting flow through the system. 

Cleaning the Kaldnes is a simple matter of turning on the air tap to the settlement area, thus agitating the static Kaldnes.  Waste is then dislodged from the media, and purged through the central vortex drain.
