The Seal HEPA Box for Pharmaceutical Cleanroom is made of high-quality cold-rolled steel plate. The surface is electrostatically sprayed,including static pressure tank, high-efficiency filter, diffuser plate, and a new level of clean room. It is used as a filter to clean the ceiling with less investment and simple construction. In order to ventilate the high-efficiency filter after obtaining the ideal static pressure, the high-efficiency filter is properly used. Compact structure, reliable performance, strong ventilation, easy installation and easy maintenance.

FAQ
1. What is the function of a high-efficiency air supply outlet?
High-efficiency air supply outlets are critical components of cleanroom ventilation systems, equipped with HEPA or ULPA filters.
They are designed to:
- Filter airborne particles (≥99.97% efficiency for particles ≥0.3μm)
- Distribute clean air uniformly (maintaining unidirectional or mixed airflow)
- Control pressure differential and air exchange rates (ensuring ISO cleanliness standards)
2. How often should the filters in high-efficiency air supply outlets be replaced?
Replacement intervals depend on the operating environment. General recommendations:
- Pre-filters: Inspect/replace every 3-6 months
- HEPA filters: Replace every 2-5 years (or when pressure drop alarms trigger)
Key influencing factors:
- Air pollution levels (e.g., pathogen-containing aerosols in pathology labs may require shorter cycles)
- Operational hours (24/7 use demands more frequent maintenance)
- Pressure differential data (replace when ΔP ≥ 1.5× initial value)
3. How to determine if a high-efficiency air supply outlet has failed?
Testing methods:
- Pressure monitoring: Significant drop in ΔP across the outlet (indicating possible damage)
- Particle counting: Downstream particle counts exceeding standards (e.g., >3,520 particles/m³ for ≥0.5μm in ISO Class 5)
- DOP/PAO leak testing: Scan filter edges and media; >0.01% leakage rate indicates failure
