Double stage / same rotation direction
Joint of 2 fans with the same rotation direction, each fan giving a pressure, the addition of these pressures is around 1.5 times higher than of one fan alone.
Double stage / contra-rotation
When the second impeller of a set of 2 fans has a reverse rotation direction than the first, the set is said to have contra-rotation and the total pressure given by the set is then around 2.3 times higher than of one fan alone.
