Cleanroom design is divided into 2 types: Industrial cleanroom and biological cleanroom. These belong to cleanroom system but have different purposes and cleanliness requirements. What is the difference between two types of cleanrooms? Let's find out.

Difference between industrial cleanroom and biological cleanroom

Industrial CleanroomBiological Cleanroom
Research objectParticles hazards to process production onceLiving particles like germs, micro-organisms grows and reproduces, which will cause second pollution
Control methodsThe main method is filtration. Coarse, medium, high and ultra-high, and chemical filters are usedThe main method is the eradication of germ growth conditions, control of the development of micro-organisms
Control ObjectivesControl the concentration of harmful particle sizeControl the generation and spread of micro-organisms
Hazards to productionA dust can cause great harm to the productMicro-organisms will become harmful only when they reach a certain concentration
Requirements for cleanroom building materialAll materials do not produce dust, frictionAll materials should be resistant to water and corrosion, not provide conditions for microbia growth
Control over the entry of people and objectBefore workers enters, they have to go through air shower. Objects should be cleaned and wipedBefore workers enters, they have to change clothes, shower and have to be sterilized. People and objects should be classified. Polluted and clean objects should be classified
DetectionParticles can be detected by particle counter, displayed and printedMicrobial detection cannot measure instantaneous value. The result can only be read after 48 hours of culture

Cleanroom system design requires strictly about cleanliness, humidity, temperature...

In cleanroom design, the ventilation is also important. The cleanliness of the ventilation system is equivalent to that of an AHU. The core of air-conditioning works is mainly ventilation, not cleanliness, so when manufacturing ventilation, choosing materials or technology is not important, but the different requirements of air conditioning room and laboratory. The material of ventilator is stainless steel.
