  F4444



DESCRIPTION

Full circle impact sprinkler. 3/4" male thread.

For agricultural usage, with medium and high flows, specially designed to equip travelling irrigation systems, such as CENTER PIVOTS and LINEAR MOVES. Due to the special features of these machines, the sprinklers to be used should be different from those used on regular on the land solid sets.

It's also highly suitable for undertree irrigation.

It's the plastic alternative to the Unirain F3030 model, though the F4444 model will be able to work with smaller nozzle sizes due to the weight difference exinting between these sprinklers.

It features two twin main nozzle water streams. This helps avoid secondary nozzle plugging and provides a higher flow per sprinkler, which helps saving money as the number of sprinklers will drop.

Its 10° water stream angle is the most suitable to reduce wind effects when installed on CENTER PIVOTS (10 to 15 ft high), achieving a lower evaporation and a higher uniformity.

Three different kinds of vanes can be used to achieve the desired throw radius - pulverisation balance according to the system pressure

Pressure (psi) Nozzles Vanes
High: 60 3RN / 3RN-P or 3FCN 30V
Medium: 28.1 3RN / 3RN-P or 3FCN Less vane
Low: 30 3RN / 3RN-P 30VR
Very low: 20 3RN / 3RN-P 30VB
