Vertical jet roof hood used for air exhaust/discharge on the roof of building. Vertical discharge on extended length prevents contamination of the air in the immediate vicinity, so an external fresh air intake can be mounted at a shorter distance.
The cap is made of galvanized sheet steel and is equipped with a mesh on the opening. On the inside, a funnel is fitted for drainage of the water originated from rain, snow or condensation, which is eliminated through a hose.
The hose can withstand temperatures between -45 °C and +65 °C.
