Lechler flat fan nozzles stand for high impact and uniform liquid distribution with spray angles up to 60°. Flat fan nozzles with low flow rates are especially suited for humidifying and spraying in general. The flow geometry of the nozzle allows the production of accurate, compact sprays, available with different distribution patterns.
Stable spray angles at a wide range of pressures. Uniform parabolic distribution.
Sharp uniform flat fan nozzle made from hardened stainless steel.
Ball joint, multi-directional swivelling range of 20°. Simple, quick assembly. Easy adjusting and cleaning. Retains orientation upon replacement.
The spray pattern of flat fan nozzles features a sharply delimited line due to internal flow characteristics. The coverage width can be varied by modifying the geometric configuration of the nozzle orifices, where the liquid is shaped into flat, fan-like spray patterns. The flat liquid body takes on a laminar form and disintegrates into droplets as its distance from the nozzle orifice increases. Parabolic, trapezoidal or rectangular impact areas are achieved by adequately determining the functional and geometric dimensions.
Regarding the flat fan spray atomization, tongue-type nozzles are of a special kind. The flat fan pattern is generated by a solid stream, impinging upon an external deflector plate (“the tongue”). Tongue-type nozzles are particularly clog-proof and produce a sharply delimited flat fan pattern.
