Air Shower Testing Standards with HICLOVER Automatic Roll Air Filter Integration

Air Shower Testing Standards with HICLOVER Automatic Roll Air Filter Integration

In modern cleanroom facilities, air showers are critical checkpoints for controlling contamination before personnel or materials enter classified areas. To ensure safe and compliant operation, every air shower unit must undergo rigorous testing after installation or commissioning. Increasingly, many manufacturers are coupling air shower systems with HICLOVER Automatic Roll Air Filters, which act as automated prefilters, enhancing airflow stability and extending HEPA life.

Key Testing Standards for Air Showers

1. HEPA Filter Leak Test
   After installation, high-efficiency filters must be checked using cleanroom construction and acceptance standards to ensure no leakage.

2. Airflow Velocity Uniformity
   According to GB 8070 methods, air shower nozzle velocity should be measured at multiple outlets and averaged to confirm uniform coverage.

3. Noise Test
   Measurements are taken 1,000 mm outside the door and 1,500 mm above the floor; noise levels must comply with applicable occupational standards.

4. Illumination
   Light levels are measured at 800 mm above the floor, with measurement points every 500 mm. Average illumination must meet prescribed thresholds.

5. Pressure Differential
   Using a manometer, pressure difference is measured between the inside and outside of the chamber 15 seconds after fan start-up. Testing is repeated three times to ensure accuracy.

6. Leakage Current
   Electrical safety standards require measurement of leakage current; values must not exceed regulations.

7. Grounding Resistance
   Grounding resistance between metal parts and the grounding terminal must be within limits, measured with specialized instruments.

8. Dielectric Strength
   The system must withstand 1-minute application of a 50 Hz sinusoidal AC voltage between power input and metal casing, without breakdown.

9. Insulation Resistance
   Measured after applying 500 V DC for 1 minute between live parts and the casing; results must comply with safety norms.

10. Electronic Interlock Test

• When the air shower is idle, opening one door must prevent the opposite door from opening.

• When in operation, both doors must remain locked.

• In power failure or lock malfunction, both doors should allow manual opening.

Added Value of Automatic Roll Filters

Integrating HICLOVER Automatic Roll Air Filters as a prefiltration stage in air showers provides significant benefits:

• Stable airflow during velocity tests by preventing filter clogging.

• Reduced maintenance with automated media replacement, lowering human error in GMP-sensitive industries.

• Extended HEPA filter lifespan, minimizing downtime in pharmaceutical and semiconductor facilities.

• Adaptability for global markets, including electronics plants in Vietnam, biotech labs in Europe, and mining support labs in Australia.
