Download ErP GuidePublished performance data is only useful if the test conditions are known and repeatable. Every Panasonic fan datasheet references the specific test standard, setup, and conditions under which measurements were taken.
Airflow and static pressure are measured using a standardized test chamber per ISO 5801:2017. The fan under test is mounted on an inlet chamber with a calibrated nozzle array. Air density is corrected to standard conditions (20C, 101.325 kPa). Flow rate measurements are taken at 8-12 operating points from free delivery to shut-off, generating the complete fan curve. Each test point is averaged over a 30-second stabilization period. Measurement uncertainty is within ±2% of reading for airflow and ±1% for static pressure.
Sound power levels are measured per ISO 13347-3 in a reverberant room with known room absorption. Measurements are taken at rated duty point and at 50% speed for variable-speed models. Sound pressure levels are reported per octave band from 63 Hz to 8 kHz, not as a single A-weighted average, because system designers need spectral data to predict acoustic impact in the installed environment. Background noise is measured separately and corrected per ISO 3746 when the difference is less than 10 dB.
Test reports are available on request for any catalog model. For configured builds, we provide a unit-specific test certificate with the tested serial number, ambient conditions, and instrument calibration dates.
The three primary fan architectures each suit different system characteristics. The following comparison uses measurable selection criteria rather than subjective rankings.
| Selection Criteria | Axial Fans | Centrifugal Fans | Mixed-Flow Fans |
|---|---|---|---|
| Static Pressure Range | 50-500 Pa | 200-3,000 Pa | 100-1,200 Pa |
| Airflow Range (catalog) | 100-65,000 CFM | 500-45,000 CFM | 200-30,000 CFM |
| Typical Efficiency (at BEP) | 55-70% | 75-88% (backward-curved) | 65-78% |
| Installation Depth | Shortest (1-1.5x diameter) | Longest (2-3x impeller width) | Medium (1.5-2x diameter) |
| Noise at Equivalent CFM | Highest (blade pass frequency dominant) | Lowest (backward-curved) | Moderate |
| Best Application | Low-resistance ducting, wall exhaust, condenser coils | High-resistance duct systems, AHU supply air, process ventilation | Medium-resistance inline ducting, compact AHU retrofit |
When system resistance is uncertain, request a selection consultation. We model the fan operating point against your estimated system curve and identify whether the fan will operate in the stable region of its performance envelope.
