If you are considering building a clean room for your workshop, pharmaceutical, research facility, electronics and chemical industries among others, there are considerations that you should take into account. Installing a clean room in any manufacturing process helps in ensuring yield optimization, quality control, and safety. However, to ensure that the clean room is effective given their potential for hazard, the design should be a careful efficient process. Here are several things to consider when building a clean room.
Types of Clean Room
There are two main types of clean room that use different methods of ventilation and hence, you should choose one that suits your needs.
1. Unidirectional Flow Clean Room
This type of clean room has high-efficiency filters that span the entire wall or ceiling of the clean room or clean room box to supply it with air. The unidirectional flow clean room works by sweeping air across the room or box in a unidirectional manner to exit through the floor hence, carrying all the airborne contaminants with it.
2. Turbulently Ventilated Clean Room
On the other hand, when thinking of how to build a clean room box, a turbulently ventilated clean room works by providing the room with clean air that passes through the air diffusers in the ceiling for filtering and is mixed with the air in the room after which any airborne contaminants present brought in by people or generated by machinery is removed with some turbulence, by use of air extracts located at the bottom of the walls.
In all cases when thinking of how to build a clean room box, you should take into account several considerations that will ensure the ideal design for your space and to suit your needs. For example, the amount of space that you will need is critical to the design process. However, you should ensure that it is a flexible design that allows for modification and expansion later.
How it will be used
Determine how the clean room box will be used. The functional and design characteristics should be determined by what you are working on for instance, whether you are working on chemical processing or electronics manufacturing among others. Since the contamination will differ based on what you work on, then the construction materials will also be different. Other factors to consider is who will use the clean room box and how frequently.
Cleanliness Rating, Space and Cost
Another thing to consider is how much space is available for the installation of the clean room box and also, what cleanliness rating your application requires. Based on International Standards Organization (ISO) classifications, the higher your cleanliness requirement the more the fan and air filter units needed and consequently, the higher the expense of installing and operating your clean room. All these will influence the air pressure needed, positioning in your application, design of the overall clean room box and energy consumption among other considerations.
