The HYDRA BIG self-cleaning filter with backwash system gives the system 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) and RLH BIG (polyester mesh), both available with a filtration degree of 50 and 90 microns.
The maximum flow rate goes from 6000 l/h with 1” models to 15000 l/h with 1”1/2 models (from 26 to 66 gpm).
Available 1” and 1”1/2 versions with BSPP and NPT plastic connections and 1” versions with BSPP and NPT-Lead Free brass connections.
Versions available with two pressure gauges.
