Frequently Asked Questions
Q
What do the model numbers (e.g., 3.15A, 4A, 6.3A) represent?
The model numbers indicate the fan size classification. The numeric value generally refers to the impeller diameter (in scaled units), while the letter "A" denotes the series type. Larger model numbers correspond to higher airflow capacity and power ratings.
Q
Why do some models offer two different speed options (960 r/min and 1450 r/min)?
Different speed settings allow the fan to be adapted to various application requirements. A lower speed (960 r/min) typically produces less noise and consumes less power, while a higher speed (1450 r/min) delivers greater airflow and total pressure, suitable for more demanding ventilation systems.
Q
What does the "Power (kW-P)" column mean — for example, "5.5-4"?
The power notation "kW-P" indicates the motor power in kilowatts followed by the number of poles. For example, "5.5-4" means a 5.5 kW motor with 4 poles. The number of poles directly affects the motor's synchronous speed and efficiency characteristics.
Q
Are all models compatible with standard 380V / 50Hz electrical supply?
Yes, all models listed in the parameters table operate on a standard 380V voltage and 50Hz frequency supply, which is the common industrial power standard in many countries. Please verify your local electrical specifications before installation.
Q
How do I select the right model based on traffic (airflow) and total pressure requirements?
First, calculate the required airflow volume (m³/h) and the static or total pressure (Pa) needed for your duct system. Then match these values against the Traffic and Total Pressure ranges in the parameters table. Choose a model whose operating range covers your target values with a reasonable safety margin.
Q
What is the significance of the Horsepower (HP) rating in the table?
The Horsepower (HP) rating provides an alternative power reference commonly used in some markets and engineering specifications. It directly corresponds to the kW power rating (approximately 1 HP ≈ 0.746 kW) and helps engineers cross-reference motor sizing with HP-based equipment standards.
