Face Velocity Calculator
To determine face velocity, divide the airflow rate (AF) by the filter’s face area (FA). This calculation provides a measure of air movement through the filter or duct system.
The Face Velocity Calculator is a practical tool for evaluating air velocity in duct systems, fume hoods, and ventilation setups. This parameter is crucial for ensuring proper airflow, maintaining efficiency, and meeting safety standards in various industrial and laboratory environments. By understanding face velocity, businesses and individuals can optimize air circulation, reduce energy costs, and comply with local exhaust ventilation (LEV) regulations.
Face velocity plays an important role in ventilation systems to maintain proper air exchange rates and to control the capture of fumes, particulates, and other contaminants. Whether managing airflow in a fume hood or ensuring HVAC system performance, this calculator is an indispensable resource for achieving precision in air movement assessments.
Formula:
| Variable | Description |
|---|---|
| FV | Face Velocity (measured in feet per minute) |
| AF | Airflow Rate (measured in cubic feet per minute, CFM) |
| FA | Face Area (measured in square feet) |
