HYDRA is a single stage self-cleaning filter with a stainless steel mesh-filter for effective removal of sediments. Easy and quick cleaning, thanks to the exclusive system with back-wash in counter- current. HYDRA can be installed as a pre-filter before your water tank to keep it clean from sediment and sludge or before your existing water filter to save on maintenance costs. Very easy to operate – simply open the valve to flush accumulated sediment out via the drain funnel. Available with blue or clear housing.
