Filtration
NOTE
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
• SpinNet™ SD micro-sprinklers are constructed without a "bridge" to retain the spinner.
This benefit produces:
a. A drip-less operation
assuring that plants placed underneath the micro-sprinklers 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".
• Interchangeable components. SpinNet™ SD micro-sprinklers can be disassembled by hand should they
need cleaning - no tools are required.
• Acid resistant (AA) raw materials, thus allowing the application chemicals to pass through the system.
• The system can be cleaned by application of suitable acid treatments.
WARNING
When handling acid, always observe the product safety instructions and avoid acid coming in
contact with the crop, the soil/substrate and the environment.
• Excellent distribution uniformity on a single irrigation line. Traditional micro-sprinkler layout spaces
the micro-sprinklers "head to head" or at spacing equal to the radius of the micro-sprinkler throw.
For larger areas, the patterns are overlapped.The SpinNet™ SD solution avoids the problems of the
traditional micro-sprinkler layout and achieves a high level of uniformity within a closely spaced "strip of
micro-sprinklers/emitters".
• The SpinNet™ SD is especially designed to facilitate full coverage of irrigated strips with excellent
distribution uniformity and high percentage of the water within the intended area.
•
It is strongly recommended to connect the SpinNet™ SD to the distribution pipe with a SSPE (super soft PE)
micro-tube, a specifically designed stabilizer and AD (anti-drain) valve that will prevent distribution pipe
drainage.
