Frequently Asked Questions
1
What is the difference between the standard fan and the Booster Net Cover version?
The Booster Net Cover version is designed to deliver higher total pressure at equivalent airflow rates. For example, the 4(16") model with the booster net cover achieves a total pressure of 600 Pa at 2900 r/min, compared to 476 Pa for the standard version — an increase of approximately 26%.
2
What voltage options are available for these fan models?
Most models support dual-voltage operation at 220V/380V, making them compatible with both single-phase and three-phase power supplies. Larger models such as the 8(32") and 9(36") are designed for 380V operation only, suitable for industrial three-phase power systems.
3
Which models support 60 Hz frequency operation?
Several models offer 60 Hz variants, including the 4(16"), 4.5(18"), 5(20"), 6(24"), 7(28"), and 8(32") models. These 60 Hz configurations typically operate at 1630 r/min and deliver higher airflow (m³/h) and total pressure (Pa) compared to their 50 Hz counterparts.
4
How do I select the right fan model based on airflow requirements?
Select a model based on your required traffic volume (m³/h) and total pressure (Pa). For light-duty applications with lower airflow needs, models such as 3.5(14") or 4(16") are suitable. For industrial or high-volume ventilation, larger models like 8(32") or 9(36") — which can deliver over 45,000 m³/h — are recommended.
5
What does the "kW-P" designation mean in the Power column?
"kW-P" refers to the power rating in kilowatts combined with the number of motor poles (P). For example, "0.75-2" indicates 0.75 kW motor power with a 2-pole configuration, which corresponds to a higher rotational speed. A "4-pole" motor runs at lower RPM and is generally more energy-efficient for continuous operation.
6
Can these fans be used in both agricultural and industrial ventilation applications?
Yes. The wide range of available models — from compact 3.5(14") units to large 9(36") fans — makes them suitable for diverse applications including greenhouse ventilation, poultry farming, industrial workshops, warehouses, and commercial HVAC systems. The availability of multiple speed and power configurations allows precise matching to specific ventilation requirements.
