Our best-selling Axial Fan

Our JM Axial Flow Fans deliver high aerodynamic efficiencies (up to 77%) 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

The Woods JM Axial Flow Fan range is available in fully-cased or short-case versions. Each impeller is manufactured from high-pressure die-cast aluminium, 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.

We also offer a High Temperature (HT) version designed to extract heat and smoke quickly and effectively in the event of a fire, and certified to run at 400°C for two hours. Find out more here.
