HVAC Clean Room Validation
Tru Cal – Standardizing the world
HVAC clean room validation is a systematic process that ensures a facility’s heating, ventilation, and air conditioning system works seamlessly with the clean room to meet stringent regulatory and operational standards.
This comprehensive approach involves evaluating critical parameters, such as airflow patterns, velocity, air changes per hour, particulate levels, pressure differentials, temperature, and humidity, to confirm consistent contamination control.
Significantly, this process is performed in several phases—including design qualification, installation qualification, operational qualification, and performance qualification—which collectively demonstrate the facility’s readiness for sensitive manufacturing or laboratory work.
Moreover, reliable HVAC clean room validation satisfies user requirements and regulatory bodies, such as ISO 14644 and GMP, while also supporting continuous monitoring and revalidation strategies to maintain long-term compliance.
As the process transitions from initial certification to routine operation, organizations must implement statistical analysis and thorough documentation. These efforts ensure that each stage of HVAC clean room validation keeps the environment within specified limits and sustainable for its intended purpose.
Scope of HVAC & Clean Room Validation
- Airflow & Air Change Rate Testing – Verifying supply air volume and circulation efficiency
- HEPA Filter Integrity Testing (DOP/PAO Test) – Ensuring filters effectively remove particulates
- Air Velocity & Uniformity Tests – Checking airflow distribution across cleanroom spaces
- Temperature & Relative Humidity Mapping – Maintaining controlled environmental conditions
- Differential Pressure & Air Balancing – Confirming pressure cascades and cleanroom segregation
- Particle Count Testing – Measuring non-viable particles as per ISO 14644 classifications
- Recovery Tests – Assessing cleanroom recovery after contamination exposure
Benefits of HVAC & Clean Room Validation
- Ensures controlled & contamination-free environments
- Meets global regulatory and GMP compliance requirements
- Reduces risks of product contamination & regulatory failures
- Enhances patient safety and product quality
- Provides documented assurance for regulatory audits
HVAC Validation – As per ISO 14644
HVAC systems are very important in cleanrooms and pharmaceutical storage areas. They control air cleanliness, temperature, humidity, and pressure. According to ISO 14644, every HVAC system must be validated to make sure it works properly and meets compliance requirements.
Our HVAC Validation Services
We provide onsite HVAC validation services as per ISO 14644, EU GMP, WHO, TGA, and MHRA guidelines. Our validation includes the following tests:
| Test | Standard | Why it is done |
|---|---|---|
| Airborne Particle Count Test | ISO 14644-1 | To check the cleanroom class based on dust/particle levels |
| HEPA Filter Integrity Test (DOP/PAO) | ISO 14644-3 | To make sure filters are working and no leaks are there |
| Air Velocity & Airflow Pattern Test (Smoke Test) | ISO 14644-3 | To see if clean air is moving in the right direction |
| Differential Pressure Test | ISO 14644-3 / EU GMP | To keep correct pressure difference between rooms |
| emperature MonitorinTg | ISO 14644-3 | To check temperature is in limit |
| Relative Humidity Monitoring | ISO 14644-3 | To confirm humidity is controlled |
| Air Change Rate Test | ISO 14644-3 | To see how many times air changes in one hour |
| Recovery Time Test | ISO 14644-3 | To measure how fast cleanroom becomes clean again after disturbance |
| Illumination Test (Light Level) | ISO 14644-3 / GMP | To ensure enough light in the cleanroom |
| Sound Level Test (Noise Check) | ISO 14644-3 / GMP | To confirm noise is within safe and acceptable level |
