O-series screen filters are used for filtration of water with low concentrations of inorganic suspended solids (eg sand). Also it can be used as a secondary filter after primary filtration systems (e.g. media filter, hydrocyclones etc.).
The installation of the filter is done by following the direction of the flow arrow in the filter body. Water enters the inlet, passes through the cartridge, filtered, and exits from the outlet. The filter is cleaned manually, disassembling the lid and removing the cartridge.
The cleaning of the cartridge should always be done when the difference of input-output pressure (DP) is 0,5 bar greater than the pressure difference when the cartridge is clean.
