Never Apply Pressure to HEPA Filters During Cleaning in GMP Facilities Never Apply Pressure to HEPA Filters During Cleaning Activities Remember: Applying pressure or physical contact with HEPA filters damages them and undermines GMP cleanroom contamination control. Why This Matters in GMP HEPA filters are critical in maintaining cleanroom classifications by removing 99.97% of particles...

Install Differential Pressure Gauges in Airlocks to Maintain GMP Zoning

digi — Sun, 25 May 2025 16:39:01 +0000

Install Differential Pressure Gauges in Airlocks to Maintain GMP Zoning Equip Airlocks with Differential Pressure Gauges for Contamination Control Remember: Differential pressure gauges in airlocks help prevent contamination by maintaining proper airflow direction between cleanroom zones. Why This Matters in GMP In GMP manufacturing, airlocks serve as buffers between areas of different cleanliness classifications. To...

Requalify HVAC Systems on Schedule to Maintain Environmental Control
