All Cleanroom process environments must remain unfailingly clean, so merely filtering the factory’s air is inadequate. To minimise particle contamination it is important to build separate environments, called cleanrooms. These areas allow particle limits to be maintained at measurable and controllable levels locally.
Clean rooms environments achieve these acute cleanliness levels by maximising laminar airflow and minimising particle traps. Laminar airflow is air moving in one direction, which allows particles to be swept away from an area within the cleanroom. Particle traps within a cleanroom environment are areas where particles gather and escape laminar airflow, such as the corners of the rooms and behind machinery and instrumentation, careful cleanroom design and placement of room furniture can minimise these areas.
In efficient cleanrooms HEPA filters installed in the ceiling allow filtered air to pass down toward the floor. The floor tiles have small holes that allow the air to pass under the floor, where air-returns (air ducts) transport the air back to the ceiling HEPA filters. This filtration process can exchange the clean room’s entire volume of air more than thirty times per hour, resulting in a very clean environment while minimising the movement of air particles.
To further reduce contamination within a cleanroom requires personnel to wear protective gowns, hair and beard covers, hoods, overshoes, and gloves. In the cleanest environments, personnel all the aforementioned clothing as cleanroom apparel is extremely important in controlling micro-contamination to contain the particles emitted by people.
We undertake the Following Cleanroom Validation Services:
- Airborne Particulate Testing
- Air Change Rate Calculations (ACR)
- Air Volume Flow Rates
- Differential Pressure Measurements
- HEPA Filter Integrity Leak Testing – DOP Method
- Temperature, Humidity, Light and Noise Level readings
- Recovery Performance testing
- Airflow Visualisation tests, supported by a full written report
- We also provide temperature mapping of rooms and storage facilities, in order to meet customers regulatory and QA requirements.
