UPSIDE-DOWN MICRO-EMITTERS HANDBOOK 29
MICRO-SPRINKLERS/EMITTERS ASSORTMENT
VibroNet™
Description
A micro-emitter designed exclusively for achieving maximum distribution uniformity with relatively small droplets.
As an integral part of its mechanism, the VibroNet™ contains a vibrating axle. The axle vibrates constantly
during operation significantly improving distribution uniformity and prevents the accumulation of lime
scale/carbonates/salts in the nozzle, thereby preventing the possibility of clogging by sedimentation and
crystallization.
Applications
The VibroNet™ is intended for use in irrigation above germination tables.
Specifications
Models 040 (blue nozzle) 050 (green nozzle)
Nominal working pressure* 3.0 bar
Flow rates at nominal working pressure 40 l/h 47 l/h
Recommended working pressure range
3.0 - 4.0 bar
Recommended filtration 130 micron / 120 mesh
*Nominal working pressure is a manufacturer defined prerequisite of the International Standard 8026 and
has no direct relationship with the recommended working pressure.
Filtration
NOTE
The filtration method is to be selected based upon the type and concentration of dirt particles
existing in the water.
• Wherever sand exceeding 2 ppm exists in the water, a hydrocyclone sand separator is to be
installed upstream from the main filter.
• When sand/silt/clay solids exceed 100 ppm, preliminary treatment is to be applied according to
guidelines issued by Netafim's team of experts.
Features and benefits
• VibroNet™ micro-emitters are constructed without a "bridge" to retain the deflector. This benefit produces:
a. A drip-less operation assuring that plants placed underneath the micro-emitters are not damaged by
water dripping.
b. A shadow-less operation providing a higher distribution uniformity without dry areas where the water
distribution is obstructed by a "bridge".
• Excellent distribution uniformity on a full coverage irrigation system.
• Operation of this emitter is based upon vibration; water passing through the nozzle causes needle
vibration, which in turn breaks up the water jet into uniform, evenly spread droplets.
• Constantly self-cleaning, the vibrating system does not allow for build up of mineral deposits in the nozzle.
• Made of quality plastic materials resistant to all agrochemicals & weather conditions.
• It is strongly recommended to connect the VibroNet™ to the distribution pipe with a SSPE (super soft PE)
micro-tube, a purpose-designed stabilizer and AD (anti-drain) valve to prevent distribution pipe drainage.
