Used for wagon drying / aeration & larger plan warehouse aeration of Cereals, rapeseed, onions & potatoes (when storing more than 8m in grain, double fans are used, in rapeseed double fans are always used due to the back pressure). Axial fans excel at high air volume produced by small motors, working range of max 80 mm ws. for single fan and 200 mm ws. when using double fans (Double fans increase pressure 2.5 times with an almost unchanged air volume).
