Frequently Asked Questions
Q
What is the speed range available for these fan models?
The fan models operate at two primary speed ratings: 1450 r/min (4-pole motors) and 960 r/min (6-pole motors). Smaller models such as 2.5A through 3.5A typically run at 1450 r/min, while larger models from 4A to 6A may offer both speed options depending on power and airflow requirements.
Q
What voltage options are supported by these fans?
Smaller models (2.5A to 3.5A) support dual voltage input of 220V / 380V, making them suitable for both single-phase and three-phase power supplies. Larger models (4A and above) are designed exclusively for 380V three-phase power supply. All models operate at a standard frequency of 50 Hz.
Q
Which model provides the highest airflow (traffic) capacity?
The 6A model offers the highest airflow capacity, ranging from 13,000 to 20,000 m³/h, with a total pressure of 1,200–1,000 Pa and a power rating of 7.5 kW (10 HP). It is ideal for large-scale industrial ventilation and air handling applications.
Q
How do I choose the right model based on power (kW) and horsepower (HP)?
Select a model based on your required airflow and total pressure. Power ranges from 0.75 kW (1 HP) for the 2.5A model up to 7.5 kW (10 HP) for the 4.5A and 6A models. Match the kW-P rating to your motor specifications and ensure the horsepower aligns with your drive system capacity for optimal performance.
Q
Can one model number have multiple configuration options?
Yes. Several models such as 3A, 3.5A, 4A, and 4.5A offer multiple configurations with different power ratings, speeds, and airflow outputs. For example, the 4A model can be configured at 1450 r/min (5.5 kW, 7.5 HP) or 960 r/min (2.2–3 kW, 3–4 HP), allowing flexibility to match specific ventilation demands.
Q
What does the total pressure (Pa) parameter indicate?
Total pressure (measured in Pascals, Pa) represents the fan's ability to overcome resistance in the duct system, including static pressure and velocity pressure. A higher Pa value indicates the fan can push air through longer or more complex duct systems. For example, the 4.5A model at 1450 r/min delivers a total pressure of 1,580–1,280 Pa, suitable for demanding HVAC installations.
