AXN-KSE 12/56

Axial fans with direct drive for building ventilation and aeration

Suitable in horizontal and vertical style.
Increase in pressure coefficients due to optimised outlet guide vanes.
The impeller blades can be steplessly adjusted without any need to disassemble the impeller. This adjustment option allows the user to make extensive adjustments to the relevant operating point, as well as subsequent motor rating corrections.
High pressure coefficients enable low circumferential speeds and therefore low-noise operation
Compact size enables installation even when space is tight
M-D style – with direct drive, with motor in outlet. Impeller assembled directly on the motor shaft
Upon request for higher pressures, or emergency mode / redundancy even possible in two-stage ZAXN-KSE 12/56 series
