  Dust-free workshops are widely used in the die-cutting and coating industry. Dust-free workshops are also called clean workshops, clean rooms, and clean rooms. It refers to the removal of particulates, harmful air, bacteria and other pollutants in the air within a certain space, and the indoor temperature, cleanliness, indoor pressure, airflow speed and airflow distribution, noise vibration and lighting, and static electricity. A specially designed room within a certain demand range. That is to say, no matter how the external air conditions change, the interior can maintain the characteristics of cleanliness, temperature, humidity and pressure that were originally set.
Which industries are suitable for dust-free workshops with different cleanliness levels
Dust-free workshops can be divided into several levels according to different factors such as regional environment and purification degree. The following is a list of the corresponding applicable industry categories according to the different cleanliness levels of the dust-free workshop, hoping to help you.
Level 100: Many people believe that this level of clean room is the most commonly used and therefore the most important clean room, which can be used for aseptic manufacturing processes in the pharmaceutical industry. This clean room is widely used, such as the manufacture of internal objects. , surgical procedures, including transplants, the manufacture of integrators, and the isolation of patients who are particularly susceptible to bacterial infections, such as after bone marrow transplants.
Class 1000: This class of clean room is mainly used for the production of high-quality optical products, as well as for testing, assembling aircraft gyroscopes, and assembling high-quality miniature bearings.
Class 10000: Class 10,000 clean room is used for the assembly of hydraulic equipment or pneumatic equipment, and in some cases, it is also used in the food and beverage industry. In addition, class 10,000 clean room is also commonly used in the pharmaceutical industry.
Class 100,000: Class 100,000 dust-free workshops are used in many industrial sectors, such as the manufacture of optical products, the manufacture of small components and large electronic systems, the manufacture of hydraulic or pneumatic systems, the production of food and beverages, and the pharmaceutical industry. This level of clean room is often used.
With the rapid development of my country's purification industry, clean room clean room has been widely used in Hui electronics, opto-magnetic technology, bioengineering, electronic equipment, precision instruments, aerospace, food industry, cosmetics industry, scientific research and teaching and other high-tech in all walks of life in the industry. Due to the huge advantages of the clean room in terms of temperature, humidity and cleanliness, its importance has gradually been recognized and accepted by people. Dust-free workshops of various scales and different cleanliness levels are playing an increasingly important role in various industries, and have made very important contributions to improving product quality and developing high-tech products.
First, the standard class of clean room is defined as follows: Class X (at Y μm )
Among them, X is the grade of the clean room, such as 100 or 10000, etc., and Y is the particle size such as 0.2μm, 0.5μm, etc., which can be checked. This means that the user specifies that the clean room particle content, at these particle sizes, must meet the limits of the class.
Here are a few examples:
Class1 (0.1μm, 0.2μm , 0.5μm)
Class 100(0.2μm , 0.5μm )
Class 100(0.1μm, 0.2μm , 0.5μm )
In Classes 100 (M3.5) and Greater (Class 100, 1000, 10000....), generally look at one particle size. In Classes Less than 100 (M3.5) (Class 10, 1.... ), it generally depends on a few more particle sizes.
The second is to specify the status of the clean room, such as:

Class X (at Y μm ),At-rest
The third is to customize the upper limit of particle concentration. Generally, the dust-free workshop is very clean when As-built, and it is not easy to test the particle control ability. At this time, you can simply lower the upper limit of acceptance, for example:
Class 10000 (0.3 μm <= 10000), As-built
Class 10000 (0.5 μm <= 1000), As-built
The purpose of this is to ensure that the cleanroom still has sufficient particle control capability when it is in Operational state.
