800mm Industrial AC Axial Fan with 7 Metal Blades and Protective Grill - High Airflow Ventilation Cooling Fan

The AC axial flow fan adopts a 7-blade metal structure optimized by aerodynamics, and the number of blades is the optimal balance point obtained through CFD flow field simulation between "air output" and "noise control"
Each metal impeller undergoes G2.5 dynamic balance calibration (ISO 1940-1) after assembly. Poor dynamic balance is the primary cause of axial fan vibration and premature bearing failure. G2.5 level calibration ensures that the fan operates smoothly for a design lifespan of over 40000 hours, without the need for mid-cycle replacement due to vibration
AC axial flow fans follow the principle of axial flow aerodynamics: air enters along the axial direction, is accelerated by rotating blades, and is discharged along the axial direction. The airflow path is short, and the resistance is low. In low-pressure and high flow scenarios, the efficiency is significantly higher than that of centrifugal fans

Q: What are the advantages of 7-leaf metal blades?
The 7 blades are the optimal balance point between airflow and noise through CFD flow field simulation. Each impeller undergoes G2.5 double-sided dynamic balancing calibration (ISO 1940-1) before leaving the factory, with a vibration speed of ≤ 2.8 mm/s; Metal blades provide a 3-level anti-corrosion solution (electrophoresis/powder coating/stainless steel SUS304), which is safer and more durable than plastic blades in high-temperature, dusty, and ammonia environments.
Q: Does it support customization?
Supports voltage/frequency customization, wire harness and connector customization, panel size customization, and OEM brand labeling. Provide DXF/STEP drawings and PQ performance curve raw data to assist clients in completing project integration.
