The Hydra Big Self-Cleaning Filter with back-wash system gives you maximum protection thanks to its high level performance.
Cleaning operations are carried out manually by the valve at the filter bottom opening up: in just a few seconds, the reverse flow of the water ejects all the impurities deposited on the cartridge surface, restoring the filter to its initial conditions.
The effectiveness of the self-cleaning process is guaranteed by the special anti-backflow device which prevents water from going back to the filter.
HYDRA BIG is equipped with two special washable filtering cartridges: RAH BIG (stainless steel mesh) of 90 microns.
The maximum flow rate is 15000 l/h with 1.5" BSP inlet & outlet connections.
