Axial Fans featuring the latest in Guide Vane Technology

Our original core JMv range has been extended and enhanced by the addition of the 1000, 1120,1250 and 1400mm sizes, which, as they feature new Guide vane technology, are known as 'JMvG' fans, but as they share a common heritage, they are still part of the JMv family.

The JMvG High Efficiency Axial fan range can deliver air flow rates up to 63.1 m³/s and static pressure up to 1650 Pa. Our JMv(G) fans can mounted into ductwork horizontally or vertically depending on the system configuration and we offer a wide range of accessories, such as mounting feet, anti-vibration mounts, matching flanges and flexible connectors. Fan casings are manufactured from galvanized steel, so have a high level of corrosion resistance, but we can also offer alternative finishes to deliver C3 corrosion resistance. Fan impellers are manufactured from Aluminum, or for specialist applications, from high grade carbon steel.

JMv(G) Axial flow fans are fully certified in accordance with EN12101-3:2015, which allows them to be driven by Frequency Converter (VSD) during a fire event, which provides fire system designers with a greater degree of functional performance.
