Class 1 Clean Room Applications
What are the Air Flow Principles of a Class 1 Clean Room?
The airflow principles for a Class 1 Clean Room are crucial for its maximum performance. ULPA or HEPA filters are used which control the laminar or turbulent airflow.
Unidirectional flow termed laminar flow directs the air containing the contaminant particles in one direction, which is usually downwards.
It is done in a continuous stream. All of the ceilings have a laminar flow where all the air in that area is directed towards the floor.
A Class 1 Clean Room is designed in such a way that it has a proper air distribution system. The system controls the air provision, distribution, and downstream air returns.
There are two types of airflows. That is vertical airflow and horizontal airflow.
For applications that need horizontal airflow, the downstream air return is utilized. Here, the ceiling-mounted air returns cannot be used.
Class 1 Clean Room HEPA Filter
How Does a Class 1 Clean Room Work?
A Class 1 Clean Room works on the principles of curation and controlled airflow while the other parameters such as temperature, pressure, and humidity are kept constant.
The air is allowed to enter the cleanroom and is run through highly precise filters built based on recent technology.
The filtered air is then either recirculated in the room or is forced outside. It depends on the mode of working of the cleanroom.
Even the smallest particles can be filtered through HEPA or ULPA filtration systems. Both these systems are extremely powerful. The use of UV radiation is also involved.
It kills the living matter such as microorganisms, bacteria in the environment, thus making it completely clean.
The following parameters shall also be strictly controlled for maximum efficiency:
- Air Pressure
What are Class 1 Clean Room Requirements?
A Class 1 Clean Room has some requirements which allow it to work to its maximum, thus producing 100% decontamination. Only a well-functioning cleanroom can be certified by ISO.
These requirements allow the cleanroom to be able to be recognized by and approved by the ISO system, which defines the standard of Class 1 Clean Room.
- It must be capable of rigorous filtration.
- It shall be able to allow and control as many air changes as it requires.
- Even the smallest particles, even smaller than a speck of dust, must be filtered through the system.
To meet the above conditions, a Class 1 Clean Room must only accommodate less than 12 particles larger than 0.3 microns.
The particles can be smaller than this measured in one cubic meter.
Wear PPE Before Working in Class 1 Clean Room
How Positive Pressure is Maintained in Class 1 Clean Room?
A positive pressure is maintained inside a Class 1 Clean Room so that no contaminant air can enter the room. The pressure difference also makes it easier to retain the clean air inside.
It is to make sure that the clean air after filtration always flows towards the less clean area.
For example, there is a room with many separate chambers. The cleanest chamber would have the highest pressure as compared to all other chambers.
There are spaces in less clean air which are later filled by the cleanest air which flows from higher pressure. Therefore the pressure needs to be maintained at different levels.
There are automated fan controls that enable the proper air distribution which suits the working of a Class 1 Clean Room.
Also, advanced technologies are being used to maintain a pressure gradient so that the airflow can be maintained.
What are the Rules of Class 1 Clean Room?
A Class 1 Clean Room has a few sets of rules which must be followed to get the highest efficiency and maximum productivity:
