GYRONET
™
TURBO MIDI-SPRINKLER
Description
Applications
Protected and open-air nurseries; intensive field crops; overhead cooling; frost mitigation; cooling irrigation;
roof and tunnel cooling and dust cleaning.
Features and benefits
Higher and better yields
• The GyroNet™ Turbo has a unique design of the sprinkler's rotor water channel, and a special shape of
the bridge, that provides very high water distribution uniformity
Saves labor cost and multiple expenses on maintenance
• Higher reliability
The GyroNet™ Turbo is made of a superior raw material composition resistant the chemicals, fertilizers,
and sun exposure.
• Guarantees lower maintenance and repair cost.
The GyroNet™ Turbo has anti-insect mechanism that is opened only during irrigation, and protects the
nozzle.
Specifications
• Very robust midi-sprinkler.
• Midi-sprinkler, 5 different flow rates: 200, 250, 300, 400, 500 l/h.
Nominal flow rates at 2.2 bar pressure.
• Maximum recommended working pressure: 3.0 bar.
• Inlet connector: 1/2" threaded male.
• Purple rotor.
• Recommended filtration : 200 micron / 80 mesh.
Selection of the filtration method should be based on the kind and concentration of dirt particles in the
water.
ATTENTION
• For water containing over 2 ppm of sand, a hydrocyclone sand separator must be installed
upstream from the main filter.
• For water containing over 100 ppm of sand/silt/clay solids, pretreatment must be performed
according to the instructions of the Netafim™ expert team.

**Do not confound isosceles with equilateral:
• An isosceles triangle is a triangle in which two sides are of equal length. The distance between 2
adjacent sprinklers on the same lateral (a) is not equal to the distance between 2 sprinklers on adjacent
laterals. The height of the triangle represents the distance between adjacent laterals (b).
Isosceles is usually referred to in open-field applications.
• An equilateral triangle is a triangle in which all three sides are equal. The distance between 2 adjacent
sprinklers on the same lateral is equal to the distance between 2 sprinklers on adjacent laterals.
Equilateral is occasionally referred to in orchards due to the tree planting pattern.

A. Distance - Distance of max. trajectory height from sprinkler nozzle.
B. height - Elevation of max. trajectory height above ground.
Trajectory height above sprinkler nozzle
The maximum trajectory height above the sprinkler nozzle is relevant in the following cases:
• When sprinklers are used under the canopy to prevent wetting the foliage.
• When sprinklers are used in a net-house or inside a roofed structure such as a glasshouse, to prevent
wetting the net or the ceiling.
