Products Description
This industrial fan is built for real energy efficiency, not a nominal efficiency-class label. The permanent-magnet synchronous direct-drive motor runs a 7,300 mm fan at under 1 kWh per hour and delivers more efficiency than a conventional asynchronous motor with a gearbox, because there are no meshing gear losses and no slip losses of a wound asynchronous rotor. The electricity saved pays back the installation cost within the first year, and one 7,300 mm fan covers up to roughly 1,500 m² and replaces about 48 small 750 mm wall fans. The efficiency class itself is to be confirmed against your exact operating point, but the mechanical package - gearless direct drive, aviation airfoil blades, 3D convection cooling, ultra-low temperature rise - is what produces the low consumption.
When a buyer compares energy-class claims across suppliers, the safest thing to compare is measured, repeatable consumption behavior rather than a label. We deliver that through batch-production consistency: every unit is 100% tested before shipment, and the same PMSM, winding and bearing spec repeats across the order so the under-1 kWh/hour performance holds fan to fan. OEM / ODM and drawing-based manufacturing let us match the efficient motor to your voltage and mounting, with in-house R&D supporting the thermal design that protects the magnets.

Applications
Energy-cost-driven plants
sub-1 kWh/hour at the largest diameter and first-year payback on electricity make the fan a direct energy-saving purchase.
Buildings replacing many small fans
one 7,300 mm unit replaces about 48 small wall fans, cutting total connected load across the floor.
Long-running 24/7 operations
the gearless, low-temperature-rise design keeps running efficiency steady through continuous duty without gearbox maintenance.
