Clean Room Introduction

Clean Room / Aseptic Clean Room

Clean Room is a room in which the concentration of airborne particles is controlled, and which is constructed and used in a manner to minimize the introduction, generation, and retention of particles inside the room, and in which other relevant parameters, e.g. temperature, humidity, and pressure, are controlled as necessary. Also, the illumination, hazardous steam, and airflow direction and its velocity are also defined. Aseptic Clean Room is a room where the Microorganisms such as bacteria or virus and biological particles are more strictly controlled.

Industrial Clean Room ICR

It is the Clean Room for industrial use, such as Precision industries, electric industries, etc.

Biological Clean Room BCR

It is the aseptic Clean Room for biological medicine or laboratories. Most of the bacteria or virus are attached to the airborne particles, which can be filtered with Filter System. However, finer bacteria can be sterilized by ultra-violet ray lamp or Hydrogen Peroxide Gas.

Definition of Cleanliness

It means the capability for the Clean Room to effectively control the particle number in the specific room. To define the function of different types of the Clean Room, we define it based on the particles of “Specific Size” in “Specific Volume”. 

Take the particle diameter above 0.5μm for example:

Countryside10,000,000 – 50,000,000 particles/m3
City100,000,000 – 500,000,000 particles/m3
Indoors100,000,000 – 1,000,000,000 particles/m3
ISO Class 5control within 3,520 particles/m3
FS 209E Class 100control within 3,520 particles/m3
