Alnor Rotating Vanes

Accurate Measurement of Turbulent Flows

Airflow across filters, coils, and large grilles is rarely uniform. Single-point measurements can be misleading in these applications. Alnor Rotating Vane Anemometers solve this by physically averaging the velocity across the large 4-inch vane head, providing a much more representative reading of the total flow.

Maintenance and Efficiency

• Filter Monitoring: Easily check face velocity across HEPA filters and pre-filters to determine loading and ensure proper airflow is maintained.
• Coil Performance: Verify airflow through heating and cooling coils to diagnose heat transfer issues or blockages.
• Grille Measurement: ideal for measuring supply and return air at registers where flow may be turbulent.
• Automatic Averaging: The instrument calculates volume based on the area, simplifying the process for the technician.

By accurately monitoring these components, you can ensure your air handling units are operating efficiently, extending equipment life and maintaining the high air quality standards required in healthcare.
