Airfoil’s Belt Drive Fans (with external or internal engine) have a firm chair (external or internal), height-adjustable, to fit in the engine: moving mechanical parts out off the case are carter-protected, steel made and properly dimensioned. Mount, shaft and transmission are carefully selected among the best components, gears are Rilsan® pipes or copper manufactured, according to project requirements.
Internal parts security is guaranteed by the peculiar composition of the protection grid, with narrower mail in proximity of rotating or moving parts. All the other features, accessories, customizing requirements and performances are common to the other kind of Airfoil International Fans, that are, as usual, top-class.
