Standard ISO Flat Fan Spray Nozzle SF Series 110° - 05 (Brown) - Code 25218
The professional-grade standard ISO flat fan spray nozzle SF series 110° - 05 (Product Code: 25218) is a high-precision fluid-dynamic component engineered for high-volume chemical distribution during agricultural spraying and crop protection. Molded from premium acetal resin (Kematal) and coded to international standard ISO 05 - Brown (equivalent to a 1.5 mm calibrated orifice), this nozzle is designed for boom assembly applications on arable land, pre-emergence setups, and field spraying treatments. When correctly spaced along the distribution rail and locked at the recommended target distance from the foliage, these nozzles yield an incredibly uniform, specular mist blanket, maximizing canopy wetting while actively suppressing chemical drift drop-offs.
Design Details and Materials Engineering (Kematal)
This technical spray nozzle is fully manufactured from high-grade industrial "Kematal" acetal resin, an advanced technical polymer renowned for its exceptional chemical stability and dimensional retention properties. This material provides the 1.5 mm orifice with outstanding structural resistance against mechanical abrasion triggered by high-velocity high-pressure fluid delivery loops, effectively eliminating premature flow-rate increases. Furthermore, the acetal matrix ensures total inertness against the aggressive chemical breakdown of concentrated herbicides, systematic fungicides, and heavy liquid insecticides, locking in a field lifespan far superior to conventional brass nozzles. The flat fan layout generates a wide 110° spray angle, geometrically calculated to establish a balanced, overlapping pattern with adjacent boom nozzles, securing exact volume-per-hectare targets across the swath without localized missing spots or chemical pooling faults.

Calibration Notes and Practical Field Guidelines
- Manifold Pressure Verification: The standard application volumes (liters-per-hectare data indexes) are calculated by cross-referencing vehicle tractor forward velocity (in km/h) with real-time hydraulic pressure. Always verify working pressure via an inline pressure gauge mounted immediately upstream of the nozzle body to rule out manifold line friction drops.
- Boom Pitch and Spacing Parameters: To maximize the distribution geometry of the 110° flat fan width, space the nozzle units evenly along the boom rail (typically adhering to a 50 cm layout interaxe) and level the boom height relative to the ground chart criteria to achieve flawless pattern overlapping.
- Orifice Unclogging and Maintenance: Despite Kematal's advanced wear resistance, insoluble residue aggregates or chemical powders can entrap the 1.5 mm section slot. Clean clogged orifices exclusively via systematic compressed air bursts or soft nylon bristles. Never utilize steel wires, welding pins, or sewing needles; hard metal items scratch the delicate polymer orifice geometry, permanently altering the spray angle and flow constants.
