To provide a filtering device that surely catches foreign matters such as sand, mud, etc., contained in a liquid for liquid spray and hardly causes filter clogging by these foreign matters and a liquid spray system equipped with the filtering device.
The liquid spray system is equipped with the filtering device 10 in the middle of a water supply flow channel. The filtering device 10 has a water inlet chamber 12 into which agricultural water drawn up from a well or a river flows and a filter 30 is attached to the upper end of the water inlet chamber. The filter 30 is obtained by knitting warps and wefts composed of filaments to give a cloth and sewing the cloth into a bag-like form and covers the opening of the upper end of the water inlet chamber 12. Since the filter 30 is composed of a cloth made by knitting filaments, the filter hardly causes clogging by foreign matters such as sand, mud, etc., contained in agricultural water.
