The WPR fans are intended for providing the main ventilation in mines. They have a radial design with adouble-sided suction impeller that can also be adapted to reverse operation.

Thanks to the featured profiled blades, the WPR fans boast silent performance and high power efficiency (82%).

WPR fans are offered in the following sizes:

  • WPR – 160/1,8
  • WPR – 180/1,8
  • WPR – 200/1,8
  • WPR – 220/1,8
