❓ Frequently Asked Questions
What is the difference between Steel and Aluminum impellers?
Steel impellers are highly durable and suitable for heavy-duty industrial applications. Aluminum impellers are lightweight, offer excellent corrosion resistance, and are highly efficient, often achieving different air volume (traffic) and pressure ranges under similar power configurations.
What are the voltage and frequency specifications for these models?
All listed models operate at a standard industrial voltage of 380V and a frequency of 50Hz, making them ideal for standard three-phase industrial power grids.
Which model provides the highest traffic (air volume) capacity?
The Model 8A provides the highest traffic capacity, delivering an airflow volume ranging from 18,850 to 32,300 m³/h, powered by a 15 kW motor (20.5 HP).
How does horsepower (HP) correlate with the power (kW) rating?
The horsepower ranges from 0.7 HP for the smallest model (3.55A) up to 20.5 HP for the largest model (8A), scaling proportionally with the motor power output (kW-P) to handle larger volumes and pressures.
Why do some models have multiple configurations for the same size?
Models like 4A, 5A, and 6.3A offer multiple configurations with different motor powers and impeller materials. This allows users to select the optimal balance of traffic (m³/h) and total pressure (Pa) required for their specific ventilation system.
