Selection Guide
Follow these steps to select the right 4-68 Centrifugal Fan model for your application.
1
Determine Required Airflow
Calculate the total airflow needed for your space. The 4-68 Centrifugal Fan covers 1,130~210,000 m3/h. Consider room volume, air changes per hour (ACH), and ventilation standards (ASHRAE 62.1, EN 16798-1).
2
Calculate System Pressure
Account for duct resistance, filters, dampers, and fittings. The 4-68 Centrifugal Fan handles pressure up to 167~2,050 Pa. Add 10-15% safety margin to your calculated total static pressure.
3
Select Motor Power
Available motor power: 0.55~90 kW. Choose IE3 high-efficiency motors for continuous operation. Ensure your power supply matches the rated voltage and frequency.
4
Choose Material & Coating
Standard: Carbon Steel / SS. For corrosive environments, upgrade to SS316L or FRP. For high-temperature applications (>150ยฐC), request heat-resistant coating and Class H motor insulation.
5
Confirm Installation & Control
Verify mounting orientation, inlet/outlet dimensions, and control requirements (VFD, two-speed, or on/off). Download the installation manual or contact our engineering team for assistance.
7
