This Netafim assembly, item 63100-058502 and model 0303420HL-B, pairs a CoolNet Pro head with its own check valve. The head is the cross configuration, carrying \u003cstrong\u003efour nozzles\u003c\/strong\u003e, and the assembly is rated at \u003cstrong\u003e8.1 GPH at 60 psi\u003c\/strong\u003e. Netafim gives CoolNet Pro an average droplet size of 65 microns at about 58 psi (4.0 bar). Its bridgeless design means no drips fall on plants below. The orange-pin check valve opens at 58 psi and closes at 26 psi, so heads stay sealed until the line reaches high pressure. With anti-drain valves at each head, Netafim says all emitters start and stop together and the pipe does not drain. Parts are made from acid-resistant (AA) materials, so suitable acid treatments can be used to clean the system. Components are interchangeable, and flushing for maintenance is straightforward. Netafim assembles this build on request, and it comes \u003cstrong\u003e25\u003c\/strong\u003e to a bag.\u003c\/p\u003e\n\u003ch2\u003eRunning a Greenhouse Fogger Head at High Pressure\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eNetafim lists CoolNet Pro for cooling, humidifying and irrigating over rooting tables. Its recommended pressure range runs from about 44 to 73 psi (3.0 to 5.0 bar). With this valve, the pump must deliver more than its opening pressure at every head before any nozzle fires. Check the pressure at the far end of the line, where friction losses leave the least. Netafim recommends connecting each head with super-soft PE micro-tube, a stabilizer and an anti-drain valve. Hang the heads level above the crop so the mist spreads evenly across the bench. Filter the water to 130 microns, which equals 120 mesh. Where sand exceeds 2 ppm, Netafim calls for a hydrocyclone ahead of the main filter. Run short pulses and watch how quickly the fog clears to judge humidity and cooling. Flush the laterals periodically to keep the fine nozzle orifices clear.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul style=\"text-align: justify;\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFour-nozzle cross head:\u003c\/strong\u003e CoolNet Pro super-fine mister in the cross configuration.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e8.1 GPH at 60 psi:\u003c\/strong\u003e Rated flow for the assembled head.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrange-pin check valve:\u003c\/strong\u003e Opens at 58 psi, closes at 26 psi; prevents drainage and drips.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e65 micron droplets:\u003c\/strong\u003e Average droplet size at 4.0 bar, per Netafim.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAcid resistant:\u003c\/strong\u003e AA materials tolerate acid cleaning treatments.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBag of 25:\u003c\/strong\u003e Assembled by Netafim on request.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable style=\"width:100%; border-collapse:collapse;\"\u003e\n  \u003cthead\u003e\n    \u003ctr style=\"background-color:#333; color:#fff;\"\u003e\n      \u003cth style=\"padding:8px; text-align:left;\"\u003eSpecification\u003c\/th\u003e\n      \u003cth style=\"padding:8px; text-align:left;\"\u003eValue\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eItem Number\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e63100-058502\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eModel\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e0303420HL-B\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eConfiguration\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eCross, 4 nozzles\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eFlow\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e8.1 GPH at 60 psi\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eCheck Valve\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eOrange pin: opens 58 psi, closes 26 psi\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eAverage Droplet Size\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e65 microns at 4.0 bar\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eRecommended Pressure Range\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e3.0-5.0 bar (about 44-73 psi)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eFiltration\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e130 micron \/ 120 mesh\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eMaterials\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eAcid resistant (AA)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003ePack Quantity\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e25\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eAvailability\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eMade on request; requires assembly time\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Netafim","offers":[{"title":"Default Title","offer_id":46414207418582,"sku":"63100-058502","price":154.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0723\/9450\/6454\/files\/growershouse--netafim--coolnet-fogger-4way-orange-pin.jpg?v=1735349384","url":"https:\/\/growershouse.com\/products\/netafim-coolnet-pro-fogger-4-nozzles-with-check-valve-orange-pin-25-pack","provider":"GrowersHouse","version":"1.0","type":"link"}
