Clean Room Preventive Maintenance: Essential Program

The Importance of Preventive Maintenance

A clean room that doesn't receive proper maintenance loses its classification. HEPA filters degrade, seals deteriorate, and differential pressures drift out of specification.

Recommended Maintenance Program

Daily - Visual verification of differential pressures - Temperature and relative humidity logging - Door and seal integrity inspection

Weekly - Surface cleaning with validated protocols - Alarm function verification - Particle count record review

Monthly - HEPA filter integrity testing - Differential pressure sensor calibration - Injection and extraction duct inspection

Semi-Annual - Partial ISO classification recertification - Deep cleaning of plenum and ductwork - Filter life assessment

Annual - Complete ISO classification recertification - Preventive HEPA filter replacement (based on service life) - HVAC system operational qualification (OQ)

Warning Signs

Watch for these signs that indicate problems:

• Differential pressure out of range for more than 1 hour
• Particle count above limit in 2 consecutive measurements
• Temperature or humidity out of specification
• Unusual HVAC system noises
