What is a cleanroom?

A cleanroom (or clean area) is essential for industries. It is an environment in which the cleanliness of the air and other parameters are controlled, monitored, and recorded (temperature, humidity, pressure, particles, and airflow). This allows products to be manufactured in the most hygienic way possible. In this way, modifications to the product are prevented, and it is guaranteed that it reaches the final consumer with quality and safety. Fume hood is used in a clean hat.

Maintaining a place prepared for handling medicines and products of different genres is essential. And clean rooms are ideal for preserving the microbiological and physical qualities of products. In other words, the environment is designed so that the conditions of texture, coloring, consistency, among others, are not changed. Besides, precisely because it is a controlled environment, there is no contamination in the production process. Fumehood is very primarily used in clean rooms.

The origin of cleanrooms

Originated inside hospitals, the concept of clean rooms did not appear "today." It emerged centuries ago, with surgeons who were largely responsible for what we know today as a cleanroom.

When noticing that bacteria were responsible for causing infections, it was necessary to develop solutions to combat such microorganisms. Therefore, they developed a solution with phenolic acid, which was used to sterilize the instruments used, when hand washing and spraying the solution in the environment. In this way, the risk of infections and contamination was reduced with the use of antiseptic.

To arrive at the method that is currently used, it took years of study and research on improvements to the controlled environment. The low hood is very popularly used in clean rooms.

Cleanroom materials

To define which materials will be needed to be used in a cleanroom project, it is necessary to carry out the analysis and have knowledge of the activities that will be carried out in the environment. In production areas, for example, it is common to use partitions, doors, white steel sheet lining, stainless steel, and glass displays.

Classification of cleanrooms

The classification of the levels of a cleanroom is obtained through analyzes in relation to the purity of the indoor air, that is, the concentration of particles per unit of volume of air and the application of its standards.

In this way, it is possible to verify which air conditioning system is the most suitable, in order to maintain a stable temperature, control the humidity level and ensure air quality, so that the environment can contain the size of the suspended particles.
