Woods Air Movement has one of the largest ranges of standard and high temperature (HT) certified Axial Fans available from any manufacturer, covering a wide range of applications including ventilation, smoke extraction, cooling and processing.
An axial fan is an exhaust fan or blower which moves gas (air, steam, fumes or smoke) through it in an axial direction - parallel to the shaft about which the blades rotate. The flow is axial at entry and exit. It is designed to produce a pressure differential which causes a flow through the fan - pulling air through the fan inlet. Factors which determine the performance of a fan include the number and shape of the blades and the speed at which they rotate. Design parameters include power, flow rate, pressure rise and efficiency. Performance is also dependant on the fan enclosure (casing) design.
Axial exhaust fans generally comprise fewer blades (two to six) than centrifugal fans and commonly have a larger radius and lower speed than ducted (in line) fans. They can be single or two-stage depending on the pressure required.
Axial fans have various blade designs including Aerofoil, Sickle, Paddle, and Variable pitch in motion.
Typical uses for Axial Fans include:
The Woods Air Movement USA axial fan range includes the highly configurable JM and JMv fans that can be configured to your requirements.
Tube Axial fans have medium pressure, high flow capability and are not equipped with guide vanes. The JM is available in standard and high temperature variants from 315mm up to 1,600mm and can be used in a variety of configurations such as two-stage (for high pressure applications), short cased or long cased.
Vane-axial fans are equipped with inlet or outlet guide vanes to control the direction the air leaves the fan, and are characterised by high pressure, medium flow capabilities. The JMv is our cutting edge, high efficiency range of guide vane fans (vane axials) that deliver class-leading energy efficiency and can generate higher levels pressure. The JMv is also available in standard temperature or High Temperature (HT) EN 12101-3:2002 certified F200, F300 and F400.
2 stage fans have two impellers rotating in opposite directions at the same time, which generates up to 2.7 times the pressure development of a single fan. A two stage configuration delivers a high efficiency and high-pressure developing, in-line solution. The JM2 features a duct-mounted terminal box for each stage.
If a fan is being installed to provide enhanced fire safety, a high temperature variant is the essential choice. Designed to perform under extreme conditions, up to 400C, our HT Axial range is designed to remove hot smoke as rapidly as possible, for a duration of up to 2 hours, in order to provide valuable time to evacuate an area and help keep smoke levels down while firefighters control the fire.
As well as complete axial fans, we also supply our class leading impellers for OEM applications such radiator cooling.
