Q1: What is a mixed flow fan?
A: A mixed flow fan combines the aerodynamic characteristics of axial and centrifugal fans. It provides a balanced combination of airflow and pressure, making it suitable for ducted ventilation and air supply applications.
Q2: What is the difference between a mixed flow fan and an axial fan?
A: A mixed flow fan generally provides higher pressure than a comparable axial fan while maintaining good airflow capacity. It is suitable for ventilation systems that require both airflow and duct pressure.
Q3: Can the SWF fan be used for smoke exhaust?
A: Yes, specially configured SWF models can be used for smoke exhaust applications. However, the fan must meet the required fire resistance rating and applicable certification standards. Please confirm the required operating temperature, duration and local regulations before ordering.
Q4: Is the SWF series available with a dual-speed motor?
A: Yes. Depending on the model, the SWF series can be supplied with single-speed or dual-speed motor configurations to meet different ventilation requirements.
Q5: Can the fan be customized according to our requirements?
A: Yes. We can discuss customized solutions based on your required airflow, pressure, motor power, voltage, frequency, installation dimensions and operating conditions.
