Watering and micro-irrigation
Watering and micro-irrigation networks require to protect solenoid valves, drip or micro-sprinklers.
The installation of a hydrocyclone or automatic filter (80 – 100 microns) avoids clogging and reduces maintenance compared to cartridge filters. Several Hectron materials are suitable for this application.
Hydrocyclones HN are the most affordable solution if presence of sand. They require manual interventions to drain the tank, but much less frequently than on a cartridge filter. They do not require any minimum pressure.
Prago filters are suitable for well water with flow rate up to 10 m³/h. They are the most affordable solution among automatic filters.
AG AUTOMATIC FILTERS
AG series filters are interesting for high flow rate, up to 340 m3/h. If needed, they are also available with very fine filtration degrees.
