Can a sink be installed in a clean room?

A Clean Room is a specially designed environment whose main purpose is to control dust particles, microorganisms and other contaminants in the air. According to the ISO 14644-1 standard, the cleanliness level of a clean room is divided into multiple levels. For example, ISO level 5 requires no more than 3,520 particles per cubic meter of air (≥0.5 microns). This means that the design of the modular clean room and the installation of equipment must be very careful to ensure that the cleanliness level of the room is not affected.

Necessity and function of sinks

In some clean rooms, it may be necessary to install sinks, especially in laboratory environments that require cleaning or chemical reagent treatment. Sinks can help researchers quickly clean equipment and ensure the smooth progress of experiments. However, this may also bring some potential contamination risks.

• Cleaning function: The sink provides convenience for the laboratory, allowing experimental equipment to be quickly cleaned to avoid the influence of contaminants on the experimental results.

• Chemical treatment: Some experiments may require the use of liquid chemical reagents, and sinks can be used to dilute or treat these reagents to ensure safety.

• Operational efficiency: A sink that provides a water source can improve the efficiency of experimental operations, reduce the movement of researchers, and improve the smoothness of work.

Impact of sinks on cleanliness

Installing a sink in a clean room may affect the cleanliness of the air. The presence of a sink may cause the generation of water vapor, aerosols or other pollutants, especially when used frequently. Therefore, these risks need to be fully considered before installing the sink.

Design considerations for installing a sink

If you decide to install a sink in a clean room, you need to consider many aspects during the design to ensure that it does not have a negative impact on the Clean room environment. This includes choosing the right material, installation location, and ventilation system.

• Material selection: The material of the sink should be made of a material that is not easy to rust and easy to clean, such as stainless steel or specific plastics, to reduce the risk of contamination.

• Location planning: The sink should be installed at the edge of the clean room or away from the work area to reduce the impact on the clean area.

• Ventilation design: It is necessary to ensure that the sink area has a good ventilation design to prevent water vapor and aerosols from affecting the air quality, and a special exhaust system may be required.

and Recommendations

it is feasible to install a sink in a modular clean room, but its impact on cleanliness needs to be carefully considered. Reasonable design and strict maintenance are the key to ensuring that the sink does not contaminate the clean room environment. If this can be done, the sink in the clean room can effectively improve experimental efficiency and safety.
