Frequently Asked Questions
A1: Backward curved impellers are highly efficient and handle large air volumes with low static pressure. They are also known for their lower noise levels (under 71db) compared to other designs.
A2: Yes, the stainless steel structure is specifically designed to resist high air temperatures and corrosion, making it ideal for industrial drying and heat treatment applications.
A3: The belt-drive method allows for flexibility in speed configuration and helps in absorbing motor vibrations, which combined with strict dynamic balancing, ensures smooth and quiet operation.
A4: Depending on the specific model and configuration, the exhaust volume ranges from 2,006 m³/h to 21,206 m³/h, providing solutions for both small and large-scale ventilation needs.
A5: Absolutely. It is widely used in canteens and commercial kitchens for effective gaseous pollutant extraction and creating a cleaner working environment.
A6: Yes, it features a stainless steel volute to reduce noise, gentle curved blade channels, and high-performance spring shocks to prevent excessive noise during high-speed operation.
