Pressure ports are specialized fittings on HEPA filtration units that allow for pressure measurement and monitoring of differential pressure across the filter media.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Leak Rate | <1x10⁻⁹ mbar·L/s (helium leak tested) | |
| Surface Finish | Ra ≤ 0.8 μm for cleanroom compatibility | |
| Connection Type | 1/4" NPT, 1/8" NPT, or G1/4 thread | |
| Pressure Rating | 0-500 Pa (0-2" H₂O) typical for HEPA monitoring | |
| Operating Temperature | -20°C to 120°C |

Pressure ports enable continuous monitoring of differential pressure across HEPA filters, which is essential for determining filter loading status, maintaining optimal airflow, ensuring filtration efficiency, and scheduling preventive maintenance before filter failure occurs.
In critical applications like pharmaceutical cleanrooms, pressure readings should be monitored continuously with automated systems. For general industrial applications, manual readings should be taken at least weekly, or as specified by the facility's SOPs and regulatory requirements.
