{"product_id":"dosatron-d25f-fixed-ratio-medicator-injector","title":"Dosatron® D25F Fixed Ratio Medicator Injector","description":"\u003ch3\u003eProduct Overview\u003c\/h3\u003e\u003cp\u003eChemical injection failure during the height of the growing season leads to immediate nutrient deficiencies, crop loss, and costly emergency repairs. When your fertigation system goes down, your crews face the pressure of manual feeding or watching high-value plant material deteriorate rapidly. With global supply chains remaining unpredictable, waiting until an old injector fails means risking long lead times and project delays that damage your reputation. Securing a reliable Dosatron unit now ensures your systems remain operational when the summer heat puts the most stress on your clients' landscapes and crops.\u003c\/p\u003e\u003cp\u003eThe Dosatron D25F Fixed Ratio Medicator stands apart from electric injectors by operating entirely on water pressure. This eliminates the need for electrical proximity and protects your installs from power surges or outages that can disable automated systems. By utilizing a fixed dose rate, you remove the risk of operator error or accidental adjustment, ensuring consistent chemical delivery every time the water flows. This simplified design reduces labor costs associated with calibration and long-term maintenance, providing you with a predictable, high-performance solution that outlasts lower-grade suction venturis.\u003c\/p\u003e\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eReinforced Polypropylene Housing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnection Size\u003c\/td\u003e\n\u003ctd\u003e3\/4 Inch NPT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePressure Range\u003c\/td\u003e\n\u003ctd\u003e4.3 to 85 PSI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFlow Range\u003c\/td\u003e\n\u003ctd\u003e0.05 to 11 GPM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInjection Ratio\u003c\/td\u003e\n\u003ctd\u003eFixed at 1:100 (1%)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeal Material\u003c\/td\u003e\n\u003ctd\u003eAF (Aflas) for common chemicals\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eAvailable Models \u0026amp; Sizes\u003c\/h3\u003e\u003cp\u003eThe Dosatron D25F is available in this fixed 1:100 ratio configuration, though the D25 series includes several adjustable and high-flow variants to suit specific gallon-per-minute requirements.

Use a bypass assembly with three ball valves to allow for easy servicing or winterization without interrupting the primary water supply. Ensure the unit is mounted vertically with the suction hose submerged in a clean stock tank, and always follow local backflow prevention codes to protect the potable water source.\u003c\/p\u003e","brand":"Dosatron","offers":[{"title":"Default Title","offer_id":52158388404513,"sku":"120608","price":274.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/8458\/3969\/files\/120608_PR_621908bf-6c7c-47c0-b72b-087c88bb8160.png?v=1766281394","url":"https:\/\/asiwsupply.com\/products\/dosatron-d25f-fixed-ratio-medicator-injector","provider":"ASIW","version":"1.0","type":"link"}
