As an addition to their standard JM Aerofoil fans, Fläkt Woods have developed a range of Large JM Aerofoil fans to provide higher pressures and volumes. The fans can be supplied with or without guide vanes, contra-rotating and as truly reversible fans, that provide the same flow in both the forward and reverse directions.
