The RL SX (DOE) washable filter cartridges are made of a polyester tubular net and characterised by double open end.
They allow a uniform water flow and limited water losses. They are manufactured without glue or sealants, by over-moulding of the rigid support over the net.
The washable filter cartridges offer an excellent cost-benefit ratio, with 4” to 20” height, capacity up to 4000 l/h and nominal 50 micron filtration. Washing the filter medium can restore conditions that are comparable to those of the new cartridge.
