Clean Room Manufacturer: Clean Room Design Guidelines
A lot of manufacturing processes require strict environmental conditions that clean rooms have to offer. Because a clean room has a mechanical system that is complex and high energy, operating, and construction cost, it is very important that a clean room manufacturer designs a clean room in a methodical way.
In this article, you will be provided with some hints on designing and evaluating clean rooms, space supply airflow, space air balance, support space requirements, etc. This guide will also help you to know if your clean room manufacturer is doing the right things. It will also give you an insight on what to expect when you hire a clean room contractor.
Evaluating the Layout for Flow of Materials and People
It is crucial to evaluate the flow of materials and people in the clean room when designing the clean room. The workers in a clean room are one of the largest source of contamination in a clean room, and the clean room manufacture needs to make sure that every critical process is isolated from pathways and access doors. The spaces that are more critical should have separate access in order to prevent it from being an access road to other spaces that are less critical.
Some processes of biopharmaceutical and pharmaceutical are vulnerable to cross-contamination from some other processes of biopharmaceutical and pharmaceutical. You need to evaluate cross contamination processes very well for inflow containment and routes of raw materials, isolation of material process, and outflow containment and route of finished products.
Determining the Classification of the Cleanliness of the Clean Room
Before you will be able to pick a classification for a clean room, you need to know the fundamental classification standard for the clean room. You also need to know the particulate performance requirements of every classification cleanliness.
The cleanliness classification of a space has a significant impact on the energy cost, maintenance, and construction of a clean room. So it is vital that your clean room manufacturer carefully evaluates contamination and rejection rates at different classifications of cleanliness and requirements of regulatory agencies. The more the sensitivity of the processes you want to carry out in the clean room, the stricter and more precise the classification of cleanliness should be.
This means this stringent cleanliness of your clean room is dependent on the requirements of your manufacturing processes. So you need to be very careful and apply caution when assigning classifications of cleanliness.
Other Variables that Needs To Be Evaluated
- Temperature: The people that work in clean rooms put on full bunny suits or smocks on their normal clothes in order to minimize potential contamination and particulate generation. Because of the extra clothing they put on, it is crucial that a lower temperature is maintained in the room for workers. To provide a much comfortable working condition for the workers, you need to maintain a temperature of between 66o to 70oF.
Vibration and Noise Level: Some precision and manufacturing processes are very sensitive to vibration and sound. So during the design, you have to put this into consideration.
