Frequently Asked Questions
Q
What is the difference between Standard grille and Boost grille in terms of airflow and pressure?
The Boost grille consistently delivers higher total pressure (Pa) compared to the Standard grille across all models, while also providing increased airflow (m³/h). For example, on the 2.5A model, the Boost grille achieves 2230 m³/h at 270 Pa versus 2100 m³/h at 215 Pa for the Standard grille. This makes the Boost grille ideal for applications requiring stronger air delivery.
Q
What voltage and frequency are these fan models designed to operate at?
All models listed — 2.5A, 3A, 4A, 5A, and 6A — are designed to operate at 220V and 50Hz. This is compatible with standard single-phase power supplies commonly used in residential and light commercial environments in many countries.
Q
Which model is best suited for large-scale ventilation requiring high airflow?
The 6A model is the most powerful option in this series, offering up to 16,250 m³/h of airflow with a total pressure of 325 Pa (Boost grille), powered by a 1.5 HP motor. It is best suited for large industrial or commercial spaces that demand high-volume air circulation.
Q
Why do the 4A, 5A, and 6A models operate at a lower speed (1450 r/min) than the 2.5A and 3A models (2900 r/min)?
The larger blade diameter of the 4A, 5A, and 6A models allows them to move significantly more air at lower rotational speeds. Running at 1450 r/min reduces noise levels, mechanical wear, and energy consumption while still achieving much higher airflow volumes than the smaller 2900 r/min models.
Q
What does the power range (e.g., 0.55-4 kW-P) indicate for each model?
The power range (kW-P) indicates the available motor power configurations for that model. Customers can select the appropriate power level based on their specific application requirements — lower power for energy-saving scenarios and higher power for demanding ventilation tasks. This flexibility makes each model adaptable to a variety of installation environments.
Q
How do I choose the right model for my ventilation needs?
Selecting the right model depends on several factors: the size of the space to be ventilated, required airflow volume (m³/h), acceptable noise levels, and available power supply. For small rooms or light-duty use, the 2.5A or 3A models are sufficient. For medium spaces, the 4A or 5A models are recommended. For large warehouses, factories, or commercial buildings, the 6A model with a Boost grille offers the highest performance. Consulting the parameter table above will help match your requirements precisely.
