The wind direction indicator is designed to indicate the strength and direction of the wind. It consists of a rotating mast, a mechanism including a basket that allows the installation of a sleeve (for airstrips and airfields suitable for nighttime operation), and a low-intensity obstruction lighting lamp mounted on top of the wind vane.

The rotary mechanism is made with double-row angular contact bearings, ensuring stable operation and resistance to thrust and radial forces. The windlass basket is made of SS316 acid-resistant steel. The windsock can optionally be equipped with a twilight sensor that activates the wind sleeve lighting and turns on the obstruction lighting fixture. The indicator can be installed on metal and breakable poles.
