Technical details and manufacturing context for HEPA/ULPA Filtration System
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Airflow Capacity | 500–2000 m³/h | Select based on room volume and required air changesISO 14644 |
| Filtration Efficiency | 99.97–99.999 % | MPPS efficiency; HEPA H13 to ULPA U17EN 1822 |
| Pressure Drop | 150–500 Pa | At rated airflow; increases with loadingEN 1822 |
| Operating Temperature | 10–60 °C | Continuous operation; higher may damage media |
| Relative Humidity | 0–95 % RH | Non-condensing; high humidity reduces efficiency |

A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
HEPA filters are rated for 0.3 micron particles at 99.97% efficiency, while ULPA filters are rated for 0.12 micron particles at 99.9995% efficiency. ULPA provides higher filtration efficiency for smaller particles.
Airflow capacity should be selected based on the room volume and required air changes per hour, as per ISO 14644. The reference range is 500–2000 m³/h, but the specific value depends on your cleanroom classification and process requirements.
The system is designed for operating temperatures between 10 and 60 °C and relative humidity between 0 and 95% RH (non-condensing). High humidity can reduce filtration efficiency, so ensure conditions stay within these ranges.
Filter replacement frequency depends on pressure drop increase due to loading. Monitor pressure drop; when it exceeds the rated range (150–500 Pa) or reaches the manufacturer's recommended limit, replace the filter to maintain performance.
