The importance of being able to offer what we call JM multi-stage, or multiple fans in series, is that we can extract more pressure development than the conventional two times pressure that you would get in a fan or pump. By contra-rotating the impellers we can get up to 2.7 times the pressure development of a single fan and increase the efficiency. This means we use both the left-hand impeller and the highly twisted right-hand free vortex impeller. A 2 stage fan can offer similar pressure development to that normally associated with centrifugal fans – and similar efficiencies. For JM Aerofoil fans, a 2 stage configuration gives an in-line solution, high efficiency and high-pressure development – the maximum for the JM Aerofoil range. MAX Fan provides one electrical connection point reducing installation time/connection costs.
