DOUBLE & TRIPLE FANS


Double fans have two impellers ranging from 1300mm up to 1600mm diameter and the metal body is made of galvanized steel St 37. Triple ones range from 1300mm up to 1400mm diameter. All kinds of fans can be stationary or travelling on both directions or can be accompanied by conical fans, which ensure an excellent air distribution and mixing. The impeller blades shaping is determined by air flow and pressure characteristics; the right rate of flow per machine allows a reduction of the number of installed fans.

ROTATING CONICAL FANS


These fans are conical constructions made of inox steel or hot galvanized steel with a single impeller vertically positioned on the top of the cone. A motor installed in the conical fan, can make the latter travelling or it can be stationary and rotated with a motor installed outside the dryer. The rotation around themselves varies: 30, 90 and 1200. They can be constructed with a single or double diaphragm for front or bilateral ventilation. The number and position of diaphragms guarantee a homogeneous air flow at every height level.
