Aim of this manual
The aim of this manual is to guide the user in setting up, installation, operaton and maintenance of the
MegaNet™ sprinkler in its various applications.
Safety instructions
• All applicable safety instructions and regulations must be observed and applied.
• The effectiveness of the equipment may be jeopardized or impaired if the equipment is used in a manner
other than that specified by the manufacturer.
WARNING
In an agricultural environment - always wear protective footwear.
CAUTION

MEGANET™ ROTATING IMPACT SPRINKLER
Description
Applications
High water trajectory angle - 24D
- for vegetables and open field crops, open field nurseries,
crops germination, frost mitigation, cooling fruit orchards and roof dust cleaning.
Low water trajectory angle - 15D
- for under-tree irrigation and shade/net houses.
Features and benefits
Ensures high and uniform yield
• The MegaNet™ has a symmetrical structure that splits the water into two equal jets. That
contributes to the balanced of the sprinkler, providing very high water distribution uniformity.
Increased germination percentage
• Thanks to the gentle water jet, and relatively small drops near the ground, the MegaNet™ does not
groove the soil along the whole irrigation event (including startup and shut off), which prevents the
seeds from being exposed - out of the soil.
Reduced maintenance cost
• The MegaNet™ has a popup mechanism that opens only during irrigation, this mechanism protects
the nozzle and protects the sprinkler's moving parts by preventing insects and dirt particles from getting
inside the sprinkler.
• Each MegaNet™ sprinkler has an integral filter that ensures clean water inside the nozzle. In addition,
this filter can be easily cleaned if needed.
• Extended product life achieved by superior raw material composition resistant the chemicals, fertilizers,
and exposure to sunlight.

• 1/2" Threaded inlet connector
• 20 MM ISO inlet connector (to be glued to PVC)
• 1/2" ASTM inlet connector (to be glued to PVC)

• 2 balanced water jets.
• Individual filter in each sprinkler.
• MegaNet™ sprinklers meet ISO 8026 standards (SI 1406) with production certified by the

• Recommended filtration: 400 micron / 40 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.
