JM Axial Flow Fans
Our Woods JM Axial Flow Fans deliver exceptional aerodynamic efficiency—up to 77%— while maintaining low specific fan power (SFP). These performance advantages are achieved through the use of aerofoil-section impeller blades and an aerodynamically optimised hub design, both engineered to deliver maximum efficiency at peak operating conditions.
Key Features
-
High-Efficiency Impeller Design
Minimises SFP values, reducing energy consumption and operating costs. -
Adjustable Pitch Impeller
Allows precise performance adjustment to meet specific system requirements. -
Installation Flexibility
Available in short- or long-cased configurations to suit different installation needs.
Precision Engineering
Each impeller is precision die-cast from aluminium and X-ray inspected using real-time radiography (ASTM E-155) to ensure structural integrity and consistent quality.
Impellers are dynamically balanced for smooth, vibration-free operation. The hub and clamp plate assembly enables manual adjustment of blade pitch angle, providing performance flexibility across a wide range of applications.
High Temperature (HT) Versions
A High Temperature (HT) variant is also available, designed to extract heat and smoke quickly and effectively in the event of a fire. This model is certified to operate at 400°C for two hours, ensuring reliability under extreme conditions.
