Ufojet

Ufojet is designed specifically for out blowing the exhaust air on the roof of the buildings.

The air is blown upwards with a high velocity and small pressure loss. The unique construction of the Ufojet prevents water penetrating into the duct system.

Ufojet includes the outer casing, air flow guidance rings and top cap, which is isolated and could be used as an access door. Ufojet also includes an air flow measurement tap. The unique construction prevents the inside of the unit from freezing.
