The ZVN 20 is a 2000 mm variable pitch, axial flow fan designed and certified by Talleres Zitron, Spain.  The fans are fabricated and assembled in Downunder Mining's premises according to the highest engineering standards.

Features include:

• adjustable blades made from aluminium alloy
• internal guide vanes that improve the fan's efficiency and structual rigidity
• hot dipped galvanised motor and fan casings
• various motors can be fitted according to the required fan duty

Advantages of the ZVN 20 over similarly sized fans are:

• the variable pitch blades make the fan more efficient over a wider range of pressures and flows
• the fans can be adjusted to provide more air only when needed reducing energy costs
• multiple, co-rotating, stages can be bolted together or separated without the use of splitters and without a loss of fan efficiency
