The Hydra self-cleaning filter is characterised by the counter-current washing system for effective sediments removal.

The cleaning operations are simple and within reach for everyone: they can take place manually by opening the drain ball valve at the bottom of the filter, or automatically, thanks to the dedicated kit auto. Process efficiency is guaranteed by the drain system designed to block reflux of the ejected water.
The Hydra self-cleaning water filter is suitable for three SX (DOE) special cartridges: RAH (stainless steel net), RLH (polyester net) and RSH (plated polypropylene net), designed for different functions and filtration levels. The IN/OUT connections available are 1/2”, 3/4”, 1”, 1”1/4”, 1”1/2” with brass or plastic thread BSP, or plastic with NPT thread 3/4”, 1” and 1/2”. The recommended capacity intervals go from 3000 to 10000 l/h. The M model is also available with two manometers and a broad range of accessories and spare parts.
The self-cleaning filters are certified by important international bodies that attest to their quality and performance, conforming to current standards
