D51 DWDI Aerofoil or Laminar Fans
Design 51 DWDI Aerofoil and Laminar impellers have ideal characteristics for variable air volume systems. With a smooth, steep pressure curve, changes in pressure cause only minor changes in volume. The broad, high, efficiency curve offers a wide range of selections from each fan size along with a wide operating range. The smooth stable air flow over the entire performance range is the result of Chicago’s Deeply spun inlet cones, impeller cones and aerofoil blades.
