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.
Our HT option not only provides clean air to work in, if fire breaks out it will efficiently extract smoke and fumes for up to two hours.
