RA BIG SX
The RA BIG SX (DOE) washable filter cartridges are equipped with stainless steel tubular filter net, external diameter 4.50”.
They are designed for specific BIG housings. They were conceived for large capacity applications and ensure long duration and optimal resistance with limited charge losses. Available with 10” or 20” height, with nominal filtration of 70 micron, they easily remove coarse sediments, in particularly dirty water.
They are offered in two different versions:
-RA-A made in AISI 316 stainless steel
-RA-C made in AISI 304 stainless steel
In order to maintain filtration efficiency unchanged, the RA BIG SX filter cartridges must be washed every 3 months.
