What are the components of clean room?

A clean room is a highly controlled environment designed to minimize the presence of airborne particles, such as dust, microorganisms, and other contaminants. It's crucial for various industries where the slightest impurity can compromise product quality, like semiconductor manufacturing, pharmaceuticals, biotechnology, and aerospace. The components of a clean room typically include:

1. Air Handling Unit (AHU): This system supplies filtered air into the clean room, maintaining a positive pressure to prevent unfiltered air from entering. It includes HEPA (High-Efficiency Particulate Air) or ULPA (Ultra-Low Penetration Air) filters that remove 99.97% to 99.999% of particles as small as 0.3 microns.

2. Air Distribution System: Diffusers and/or laminar flow hoods distribute the filtered air uniformly throughout the space to maintain the desired cleanliness level. This may involve uni-directional or turbulent airflow patterns depending on the clean room classification.

3. Partitions and Ceilings: These are made of materials that are easy to clean and do not shed particles. They often have flush construction with no gaps to trap dirt and dust. The ceiling may contain return air grilles or plenums.

4. Flooring: Smooth, nonporous flooring materials such as epoxy resin, vinyl or polyurethane are used which can withstand heavy traffic, resist chemicals, and be easily cleaned. In some cases, raised floors are used to allow for underfloor air distribution and services.

5. Lighting: Sealed, low-particulate emitting fixtures that are easy to clean are installed to avoid contamination from bulbs or fixtures themselves.

6. Entry Systems: Airlocks or gowning rooms are used for personnel entry and exit to minimize the introduction of contaminants. They might include air showers, pass-through chambers for materials, and sticky mats to remove particulates from shoes.

7. Monitoring Systems: Particle counters, humidity and temperature sensors are used to continuously monitor the cleanliness and environmental conditions within the clean room.

8. Personnel Protective Equipment (PPE): Cleanroom suits, bouffant caps, face masks, gloves, and shoe covers worn by personnel inside the clean room help prevent human-generated contamination.

9. Pharmaceutical Cleanroom Equipment: Specialized cleaning tools and equipment, including vacuum cleaners with HEPA filters, mops, and disinfectants, are used to maintain the cleanliness of the environment.

Application:

In order to ensure the cleanliness of the air necessary in the clean room, to reduce or prevent indoor dust production and growth of microorganisms, reduce or prevent the introduction of particles, microorganisms or materials that may cause cross-contamination into the clean room, Pharma clean room facility effectively removing indoor particles / microorganisms discharge.

In order to achieve the ideal purification effect and reduce the purification cost, local air purification equipment is often used, including pass box, clean bench, fume hood, weighing booth,laminar flow hood,etc.

Characteristic:

Clean room equipment includes air purification equipment and air ventilation equipment. During the construction process, it is necessary to select the appropriate air filtration equipment according to specific practical needs. In general, the selection of air purification equipment will use coupled filtration technology to achieve the purpose of eliminating dust in the air, that is, through multiple layers of different filtration forms, to eliminate foreign particles and harmful substances in the air.
