What is a class 1000 clean room


Dust-free workshop refers to the removal of particulates, harmful air, bacteria, and other pollutants in the air within a certain space. Specially designed rooms within certain requirements. That is to say, no matter how the external air conditions change, the indoor can maintain the characteristics of the cleanliness, temperature, humidity, and pressure performance that were originally set. The main function of the clean room is to control the cleanliness of the atmosphere and the temperature and humidity of the product, so that the product can be produced and manufactured in a good environmental space.

Purification principle

Airflow → Effective air treatment → Air conditioning → Medium effect air treatment → Pressurized air supply of fans → Purified air supply ducts → Efficient air supply outlets → Clean room → Take away dust (bacteria) → Return air duct → Fresh air and primary effect air treatment .

Repeat the above process to achieve the purpose of purification.
