Ocmis VIR8A Turbine Drive Hard Hose Irrigator

Overview

The Ocmis VIR8A is a professional-grade turbine drive hard hose irrigator manufactured by Ocmis Irrigazione, one of Italy's most respected irrigation equipment specialists. This large-capacity reel irrigator is engineered specifically for handling large-diameter hoses, featuring a robust 4-wheel chassis with advanced hydraulic systems that provide exceptional stability and operational control. Designed for large-scale agricultural operations, the VIR8A delivers reliable performance across hose configurations ranging from 110 mm to 140 mm (4.33 to 5.51 inches) in diameter and extending up to 730 metres (2,395 feet) in length.

What distinguishes the VIR8A is its integration of the innovative Vario Rain system powered by a 4-speed synchronized gearbox, representing Ocmis's latest generation of irrigation technology. This nerve centre of the machine enables precise control over water application rates, delivering significant water savings whilst maintaining optimal irrigation uniformity. The turbine drive system is flanged directly to the gearbox with a double built-in bypass, ensuring consistent retraction speeds without significant pressure losses. Combined with the Aqua System computer control, hydraulic lifting and rotation systems, and hot galvanized chassis with epoxy resin coating, the VIR8A offers the user-friendliness and durability demanded by modern commercial farming operations.
