Filters

In-line filters eliminate lime, sand and dirt before they can be introduced into the irrigation system.
The use of a filter is highly recommended, especially for micro-irrigation and drip pipes, but the use of a filter is generally recommended for all forms of irrigation. Organic material such as leaf pieces or pollen can clog the nozzles and filigree channels of the irrigation system. Likewise, inorganic material such as sand, for example, when using well and cistern water, can be filtered out with before it is fed into the irrigation system.
Varying filter sizes can be used depending on the expected quantity of dirt in the water.
Available filter sizes are:

• ¾ inch
• 1 inch
• 1 ½ inch
• 2 inch

In general, the following applies: The larger the filter, the less pressure reduction at a specific flow rate. In a direct comparison between a screen filter and a disc filter, the latter has a higher filter capacity. Screen filters, on the other hand, can be cleaned more conveniently by simply flushing them out.
The filter performance can be monitored using a manometer. For this purpose, measured values are determined before and after the filter, which would indicate the pressure drop difference.
