Mister vs. Fogger
The following refers solely to misting systems that function properly at a working pressure of 4.0-6.0 bar.
There are irrigation companies that offer "Fogger" (the trade name) products that actually sprinkle droplets
of approximately 100 microns at best. Without getting into the discussion whether it is right to give a trade
name to a product that implicitly links it to a standard it does not meet, it is highly recommended that you
become familiar with the products' actual performance.
To clarify: Netafim's CoolNet Pro™ mister provides, under optimal working conditions, a very gentle mist
with droplets of an average size of 65 microns at a 4.0 bar working pressure.
At a working pressure above 4 bar, the size of the droplets will decrease only slightly.

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
• CoolNet Pro™ misters are constructed without a "bridge" to retain the deflector.
This benefit produces:
a. A drip-less operation assuring that plants placed underneath the misters 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.
• 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.
