F26



FT102 Feedtube
DESCRIPTION

Full circle impact sprinkler. 1/2" Male thread. 23° water stream angle. Very suitable for low and medium flow solid sets.

Created to stand the toughest working conditions, it features some major and significant improvements that emphasize its durability.

Made from high resistance thermoplastics with UV radiation protection, and stainless steel.

Its bearing sleeve thread is protected to prevent breaking up from impacts.

Its bearing guides the bearing spring protector to grant a correct sliding of the sprinkler body base on the protector itself.

Due to an innovative system, the crown that holds the arm spring allows tension variation to adjust the sprinkler performance to extreme pressure and flow conditions, and it's protected against impacts or debris by a cap.

Thanks to their bayonet coupling system, the 3Q nozzles make cleaning and changing easy. They're made of anti-abrasive acethal resin and color coded, and their millimeter and inch sizes are carved for an unmistakable identification.

Just like the rest of the Unirain range of sprinklers, the F26 model allows using three different vanes to achieve the desired coverage and pulverization balance according to the available system pressure.
