The patented tube design with slots improves the venturi effect throughout the entire length of the tube.
The aluminum tube has an opening diameter of 38 mm.
The correct length of the Venturi tube depends on the diameter of the ventilation duct.
The Venturi tubes are available in three lengths: 0.6, 1.5 and 2.8 m. For ducts with less than 0.6 m, we recommend Venturi tube length 0.6 m.
For ducts from 0.6 to 1.3 m, we recommend Venturi tube length 1.5 m.
Concerning ducts over 1.4 m, we recommend Venturi tube with length of 2.8 m.
For any diameter of the ventilation duct exceeding 0.6 m, a passage of the entire duct by the Venturi tube is to be made sure.
