How to select the right ventilator fan – 3 simple steps
Define your design envelope: target CFM (50~2000), max static pressure (Pa), noise limit (dB(A)), and housing size.
Share with our engineers: We run performance matching and recommend 2-3 centrifugal fan models (AC/DC/EC) with curve overlap.
Sample validation: You receive samples, integrate into your ventilator prototype, and measure real-world result.
Most ventilator OEMs find the optimal balance with EC backward-curved fans – highest efficiency and smart control ready.

FAQ of Ventilator Fans
Why is my equipment still overheating even though a fan is installed?
This is usually due to insufficient Static Pressure.
The Issue: Standard axial fans move a lot of air in open spaces but “stall” when they hit resistance (like dense wiring, filters, or narrow heatsinks).
The Solution: You need a Centrifugal Fan. These are designed to “compress” the air and generate the pressure required to force airflow through tight spaces and overcome internal resistance.
When selecting a fan, should I prioritize Airflow (CFM) or Static Pressure?
It depends entirely on the System Resistance (Impedance).
Prioritize Airflow (m³/h or CFM): For open-space ventilation with no filters or ducting.
Prioritize Static Pressure (Pa or Inch $H_2O$): For industrial electrical cabinets, telecommunication enclosures, or systems with HEPA filters. In these cases, high airflow is useless if the fan cannot overcome the “backpressure” of the cabinet.
How can I reduce the noise of a Centrifugal Ventilator?
Industrial noise is often a mix of mechanical vibration and air turbulence.
Switch to EC Motors: EC (Electronically Commutated) fans are significantly quieter than AC fans, especially when running at partial speeds.
Optimize the Operating Point: Every fan has a “Performance Curve.” Noise is highest when the fan is struggling against too much resistance. Ensure your fan is sized so it operates in its high-efficiency window.
Vibration Dampening: Use rubber mounts or flexible gaskets between the fan housing and the equipment frame to prevent resonance.
What type of impeller should I choose for dusty environments?
Go with Backward Curved Impellers.
Unlike “Forward Curved” blades, backward curved blades are less prone to dust accumulation. This prevents the fan from becoming “unbalanced,” which would otherwise lead to bearing failure and excessive vibration in harsh industrial or factory environments.
What is the best installation practice for cabinet cooling?
For most industrial electrical cabinets, the “Exhaust” (Top-Mount) configuration is preferred.
By placing the centrifugal fan at the top to pull hot air out, you create negative pressure. This draws cool air in through bottom filters, ensuring a more uniform temperature distribution across all internal components.
