It's a shape and size that always makes you look twice – even our staff in final assembly never fail to be impressed. The impeller has a diameter of 4,800 mm, the flanged shaft a length of 11,300 mm, and each unit has an overall weight of just under 45 tons. Venti recently delivered two of these imposing rotors to keep fresh air circulating into a mine.
But it's not only the size that's special. The rotors' outstanding rotational characteristics as well as their balance quality (Q2.5) make for low-vibration, long-life operation.
And even with rotors in these immense dimensions, our profiled blades are providing better flow guidance, higher efficiencies and thus lower energy costs to our customers.
