On the corresponding measurement surface, the air volume can be calculated by multiplying the average wind speed by the effective area. If the wind speed unit is m/s and the area is m², the result is m³/s; convert to m³/h and multiply by 3600. The premise is that the wind speed and area come from the same ventilation section.

Average wind speed requires representative measurement points

When the air flow is uneven, a single point wind speed cannot be used to represent the entire surface. The points should be laid out according to the applicable measurement plan, and the corresponding averaging method should be used; the area cannot be arbitrarily used to use the box shape or the filter material expansion area.

Pay attention to actual measurement boundaries

Filters, screens and diffuser structures can affect local distribution. If air volume hood or air duct measurement is used, the equipment operating conditions, measurement methods and instrument errors need to be checked when comparing with the face wind speed estimate.

Scene judgment

When the effective area is 0.5m² and the average wind speed is 0.4m/s, the estimated air volume is 720m³/h; this value is only calculated based on the corresponding cross-section and does not directly prove the cleanliness level.

Item Check Points

Aili industrial equipment supporting support

Aili Industrial has the ability to coordinate and support motors, fans and control systems, and can match air supply equipment and control methods according to actual operating conditions. Airflow configuration should be confirmed with filter resistance, structural interfaces and site protection objectives, and operational benefits evaluated with specific operating conditions data.
