Frequently Asked Questions
What are the main benefits of a backward curved impeller?
A backward curved centrifugal impeller is ideal for applications requiring high airflow and low static pressure. It minimizes component force loss, significantly improves exhaust efficiency, and operates with low noise (under 71dB).
Why is stainless steel used for the blower structure?
Stainless steel provides excellent resistance to high air temperatures and corrosive stains. This allows the blower to operate stably in harsh industrial drying, heat treatment, and kitchen exhaust environments while reducing volute noise.
What is the exhaust volume range of the Ventto Centrifugal Blower?
Depending on the model, the exhaust volume ranges from 2006 m³/h to 21,206 m³/h, allowing efficient extraction of gaseous pollutants and hot air.
How does the belt-drive motor system prevent excessive noise?
The strong power motor drives the impeller via a belt system. Both the impeller and belt undergo strict dynamic and static balance corrections, supported by high-performance spring shocks to minimize operational noise and vibration.
Where can the Commercial Backward Curved Centrifugal Blower be applied?
It is widely used in commercial canteens, factories, power plants, warehouses, large plazas, generator rooms, and hot air circulation systems.
What voltages and power options are available for these blowers?
The blowers operate on a 380V voltage system, with power ratings ranging from 1.1KW up to 22KW, depending on the specific model and performance requirements.
