💡 Frequently Asked Questions
What does the "Traffic (m³/h)" parameter indicate?
The "Traffic" or airflow volume measures the amount of air the unit can move per hour. It is a crucial metric for determining if the selected model meets your specific ventilation, cooling, or air circulation requirements.
How do I choose the correct voltage for my equipment?
Our models support various configurations including 220V, 380V, or dual 220/380V setups. You should verify your local power supply and facility's electrical infrastructure before selecting a specific model to ensure compatibility.
What is the significance of the "Total pressure (Pa)"?
Total pressure represents the aerodynamic resistance the equipment can overcome. Higher total pressure is typically required for complex systems with long ductwork, multiple bends, or dense filtration setups.
Why do some models have multiple speed and power ratings?
Models such as the 3.2A and 4A feature configurations that allow them to operate at different speeds (e.g., 2900 r/min vs 1450 r/min). This multi-rating design provides flexibility, allowing the equipment to be adapted to different performance levels and energy requirements.
Can the speed (r/min) be adjusted during operation?
The speeds listed in the parameters are the nominal operating speeds. If you require variable speed control during operation, an external Variable Frequency Drive (VFD) may be needed depending on the specific motor type installed.
Are these models suitable for 60Hz power grids?
The parameters provided in this table are specifically calibrated for a 50Hz frequency power grid. Operating these units on a 60Hz grid will alter the motor speed, power consumption, and overall aerodynamic performance.
