Frequently Asked Questions
What is the standard operating frequency for these models?
All models detailed in the parameters table are designed to operate at a standard frequency of 50 Hz.
Which models support dual voltage (220/380V)?
The smaller models ranging from 2.8A up to the 3.5A (3 HP version) support dual voltage of 220/380V. The larger models starting from the 3.5A (4 HP version) require a 380V power supply.
What is the maximum traffic (airflow) capacity available?
The 5A model offers the highest traffic capacity, capable of reaching up to 18,320 m³/h when operating at 1450 r/min with a 10 HP motor.
Do all models run at the same speed?
Most models operate at a standard speed of 1450 r/min. However, the 5A model also offers a configuration that runs at a lower speed of 960 r/min.
What is the total pressure range for the 4.5A model?
The 4.5A model generates a total pressure ranging from 1600 Pa to 1170 Pa, powered by a 7.5 HP motor.
