4. Product Features
All series are equipped with pure copper coil motors, which have excellent electrical conductivity, stable and strong power output, high starting torque, can start with load, low temperature rise and low loss during operation, and longer service life. At the same time, it achieves a balance between large airflow and low noise. The 16-inch model has a running noise as low as 35dB/A, which does not affect the working environment.
The blades are thickened and enlarged, with anti-rust treatment on the surface, not easy to deform and corrosion-resistant. The product strictly controls the angle and thickness of the blades, optimizes the circumferential speed and axial speed at the inlet and outlet of the air surface, and greatly improves the working efficiency of the fan. Among them, the 20-inch model has an airflow of up to 7500m³/h, with a longer air supply distance and a wider air coverage range.
Covers 16/18/20-inch full sizes, you can freely choose according to the space size and airflow demand of the scenario; all series are equipped with 4-speed adjustment, taking into account energy saving and air supply effect. With an adjustable U-shaped bracket, you can easily adjust the air supply direction to meet the ventilation needs of different spaces.
The front and rear are equipped with high-density metal protective grilles, which can prevent foreign objects from entering the motor and damaging the equipment, and effectively avoid accidental contact injuries. The fuselage is made of thickened material, not easy to deform, and has strong impact resistance, suitable for the complex use environment of industrial scenarios.
The 16-inch model is lightweight and easy to carry, with an integrated handle for easy movement and handling; all series are equipped with non-slip foot pads on the bottom bracket, which are stable when placed and not easy to shake during operation, making use safer.
5. Product Installation and Instructions
Installation Steps
Unboxing Inspection: Confirm that the High airflow industrial floor fan body, bracket, power cord and other accessories are complete and free of transportation damage.
Bracket Assembly: Connect the U-shaped bracket to the fan body through fixing screws, and tighten the nuts to ensure the bracket is stable.
Placement and Debugging: Place the fan on a flat ground, adjust the bracket angle to ensure the fuselage is horizontal and stable.
Power-On Test: Connect to 220V power supply, turn on the High airflow industrial floor fan to test the operation status of each gear, check whether the air supply is normal and there is no abnormal noise.
Usage Instructions
- The device only supports 220V AC power supply, and overvoltage use is prohibited.
- Keep foreign objects away from the protective grille during operation, and do not touch the blades with your hands.
- Regularly clean the dust on the protective grille and blades to avoid blockage affecting the air supply efficiency.
- When not in use for a long time, disconnect the power supply and store it in a dry and ventilated place.
