What is a Class 1 Clean Room?

A Class 1 Clean Room is a room where the number of airborne contaminant particles is controlled.

Other environment parameters like temperature, moisture, and airflow are also under system control.

The purpose of the construction of Class 1 Clean Room is to create an environment where the introduction, production, and retention of contaminant particles are minimum.

According to the ISO classification system, it is the cleanest of all other clean rooms which means that it has the most precise results and maximum increase in productivity.

ISO classification system is universal and it enables the Class 1 Clean Room to undergo 500-700 air changes per hour. Only 12 particles in each cubic meter of 0.3 micrometers are allowed.

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:

• Filtration

• Airflow

• Temperature

• Air Pressure

• Humidity

• Light

• Electricity

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.

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:

• There should be no room for allowance of any contaminant particles to enter the room. No matter what the source is, every potential source must be monitored thoroughly.

• The equipment or apparatus in Class 1 Clean Room shall not give rise to any contaminants. The quality shall be up to the mark so that there is no increase in contamination.

• Even if there are any reactions to take place, like chemical reactions, the by-products shall not affect the sanitation of the room.

• There shall be no chance of any accumulation of the contaminants. It gets difficult to get rid of the accumulations and therefore it shall be designed in such a way that the contaminants have no room to accumulate.

• The particles that are in the room shall be removed. It shall be done as quickly as possible.

What are the Airborne Particle Characteristics for a Class 1 Clean Room?

The characteristics for airborne particles of Class 1 Clean Room are as follows:

• Airborne particles refer to the particles that are suspended in the air.

• It shall have definite physical boundaries. This implies all directions.

• The diameter shall fall in the range of 0.001 to 100 microns.

• All the solid or liquid phase material characteristics also hold for the contaminant particles.
