Powerfoil D is the environmental-duty choice: IP66 protection, a neodymium permanent-magnet direct-drive motor and controls ready for demanding facilities.

Protection against dust, water and vapours supports indoor, covered outdoor, washdown and high-humidity applications.
A permanent-magnet motor and VFD reduce drivetrain complexity while supporting quiet, efficient operation.
Current diameters span 2.4 to 7.3 metres, allowing a project team to match the fan to building geometry and mounting height.
0–10 VDC, Modbus and BACnet compatibility plus SmartSense® automated modes support building-management workflows.
