What is the difference between an explosion-proof air shower and an ordinary air shower?

Explosion-proof air shower rooms and ordinary air shower rooms in the design purpose, use of the environment, safety performance, and internal configuration, there are obvious differences, the following is a specific comparison:
Design purpose
Explosion-proof air shower: The main purpose is to ensure that when personnel and materials enter a specific area in a flammable and explosive environment, they will not cause safety accidents such as explosions due to static electricity, sparks, etc., and can also achieve the purification function of personnel and materials.
Ordinary air shower room: mainly to meet the general cleaning needs, by blowing to remove dust hair, and other impurities on the surface of personnel and materials, to provide a relatively clean environment for clean room and other areas, to ensure that production or experiments and other activities are not affected by dust and other pollutants.
Use environment
Explosion-proof air shower room: often used in petroleum, chemical, natural gas, pharmaceutical, military, and other flammable and explosive gases, steam, dust, and other dangerous substances. For example, petrochemical production workshops, oil depots, factories producing fireworks, and other areas, these places have extremely high requirements for explosion-proof.
Ordinary air shower room: suitable for places where cleanliness is required but there is no flammable and explosive danger, such as electronic semiconductor production workshops, food processing workshops, hospital operating rooms, laboratories, etc.
Safety performance
Explosion-proof air shower: with higher safety standards and strict explosion-proof design. Its electrical system uses explosion-proof electrical components, such as explosion-proof motors, explosion-proof switches, etc. All parts that may produce electrical sparks or static electricity are specially treated to prevent explosions during operation. In addition, it also has a good grounding system, which can introduce static electricity to the ground in time to eliminate hidden electrostatic hazards.
Ordinary air shower room: mainly focuses on meeting basic electrical and mechanical safety requirements, such as grounding protection, leakage protection, etc., to prevent general safety accidents such as electrical failures and mechanical injuries, but does not have a special explosion-proof function.
Internal configuration
Explosion-proof air shower: To achieve an explosion-proof function, its internal configuration is different from that of an ordinary air shower. For example, its fans usually use explosion-proof fans, which are designed and manufactured with special explosion-proof measures and can operate safely in flammable and explosive environments. At the same time, components such as filters also need to have corresponding explosion-proof performance to ensure no danger during the filtration process.
Ordinary air shower: It is equipped with an ordinary fan filter and other components. The fan mainly meets the requirements of providing sufficient blowing speed and air volume, and the filter selects the corresponding grade of products according to different cleanliness requirements, such as initial effect, medium effect, high-efficiency filter, etc., to achieve a good filtration effect.
Material and structure
Explosion-proof air shower: Materials with higher strength and explosion-proof performance are usually used, such as stainless steel whose thickness may be thicker to enhance the impact resistance and overall stability of the equipment. The structural design is also more robust, with better sealing, to prevent flammable and explosive gases from entering the air shower room, but also to avoid internal sparks and other dangerous factors that may leak into the external environment.
Ordinary air shower room: The material and structure are mainly considered to meet the requirements of cleanliness and general use strength. The material is generally made of ordinary stainless steel or other materials that meet the requirements of hygiene and cleanliness, and the structural design pays attention to easy cleaning, and maintenance and ensures good airflow organization to achieve efficient blowing and filtering effects.
Price
Explosion-proof air shower: Due to its special explosion-proof design, the use of high-quality explosion-proof components, and strict manufacturing process and testing standards, the price is relatively high.
Ordinary air shower room: the price is relatively low, its cost is mainly focused on meeting the basic clean function and general safety requirements, and there is no additional cost caused by special functions such as explosion protection.
