FILTERS FOR SPRAYING SYSTEMS — PROTECTION OF PUMPS, LANCES, AND NOZZLES FROM IMPURITIES AND PARTICULATES

Filters

Dal Degan sprayer filters are essential components to ensure the correct operation of atomizers, sprayers, sprayer units, backpack pumps, and pressure pumps. Their function is to protect the entire spraying system from impurities in the water and plant protection products, preventing nozzle clogging, premature pump wear, and damage to the control valves. An effective filtration system improves the quality of phytosanitary treatments, reduces maintenance, and helps increase the lifespan of the entire spraying machine. For this reason, Dal Degan offers a complete range of filters for atomizers and sprayers, suitable both for its own machines and for most equipment on the market. Suction filters for water intake Suction filters represent the first level of system protection. They are installed at the end of the suction hose when loading water from ditches, canals, tanks, cisterns, and collection basins. Their function is to trap sand, soil, leaves, plant residues, and other impurities before they can reach the pump. This water suction filter is particularly useful for atomizers, sprayers, and sprayer units that frequently fill directly in the field. Made of chemical-resistant plastic materials, they are available in various sizes and diameters to adapt to different flow rates and system configurations. Filters for lances and pressure pumps Dal Degan lances and handles integrate specific safety filters designed to protect the nozzle from the finest particles that could bypass other filtration systems on the machine. In versions with a plastic handle, a filter made of technical material resistant to phytosanitary products is used, which is easily replaceable during routine maintenance. For professional brass lances, brass filters with high mechanical and chemical resistance are available, ideal for intensive and professional use. Stage filtration for greater protection Maximum efficiency is achieved through multi-level filtration. The suction filter protects the pump from coarser impurities, while the filters installed on the lances trap the finest particles before they reach the nozzle. This staged filtration system ensures uniform product distribution, reduces the risk of clogging, and improves the quality of phytosanitary treatments in vineyards, orchards, olive groves, greenhouses, and extensive crops. Compatibility with atomizers and sprayers All Dal Degan filters are designed according to the most common industry standards and are compatible with atomizers, sprayers, sprayer units, backpack pumps, and pressure pumps. They can be used both as spare parts and as upgrades for existing systems. Thanks to their reliability and the quality of the materials used, Dal Degan filters represent a professional solution to improve the protection of the spraying system and ensure more effective, uniform, and safe treatments over time.
