Our JM Aerofoil fans deliver high aerodynamic efficiencies (up to 79%) and low specific fan powers. These benefits are achieved using Aerofoil section impeller blades and aerodynamically optimized hub design, which deliver peak operating efficiencies.
  • High Efficiency impeller design reduces SFP values and running costs
  • Adjustable pitch impeller delivers precise performance
  • Short or Long cased options provide installation flexibility


Our JM product is available as a fully cased or short case axial flow fan which offers high efficiency performance. Each impeller is manufactured from high-pressure die cast aluminum, which is X-ray inspected using real time radiography (in accordance with ASTM E-155) to ensure product integrity and quality. Impellers are precision balanced to minimize vibration levels and assure smooth operation. Impeller blades are mounted into a hub and clamp plate assembly, which allows manual blade pitch angle adjustment that offers performance flexibility.
