Self-cleaning filter HYDRA K DP is characterised by the brass manifold, suitable for supporting heavy stress during the installation and operating phases.

The counter-current washing system guarantees effective and total cartridge cleaning, maintaining its filter capacity over time. Sediments removal can take place in two ways: by manually opening the drain ball valve at the bottom of the filter, or automatically, thanks to the kit auto available upon request.
The drain system stops contamination from water reflux.
The self-cleaning potable water filter Hydra K DP can be used with SX cartridges: RAH (stainless steel net), RLH (polyester net) and RSH (plated polypropylene net), designed for different uses. The available IN/OUT connections are 3/4” and 1”, with brass thread BSP type. The capacity intervals go from 5000 to 6000 l/h. The variation with manometer M is also provided for complete control of entering and exiting pressure.                      
Atlas Filtri undertakes to offer the best quality of materials and products through a careful design, constant testing and adopting innovative technologies.
