What is an air shower? What is a buffer room? What is an air lock room? What is the function of the air shower? What is the function of the buffer? What is the purpose of the air lock chamber? What are the differences and connections between air shower room, buffer room and air lock room?

The following is a detailed elaboration by the small edition of the star enterprises in the field of purification equipment manufacturing and purification engineering:

Air shower room, also known as the air shower room, air shower door, air shower machine, air shower room, dust bathroom, air disinfection room, mainly composed of fan, high efficiency filter, control circuit, box and other large components, the air shower room is necessary for clean room entrance purification equipment, its main role is to get rid of the dust on the body by blowing to achieve the purpose of purification, as long as the wind is enough, You can get rid of most of the dust on the body, of course, this is just one of the functions of the shower. One of the most important functions of the air shower room is to effectively isolate the effective barrier between the clean room and the outside world. The main difference between the air shower room and the buffer room and the air lock room is that the air shower room has the function of purifying and filtering.

Buffer chamber: The buffer room structure and the air shower room is roughly the same, mainly reflected in the internal and external box structure and size space, it is less than the air shower room is mainly in without the shower, so the internal air shower room is also less of the main control system and purification filter and fan, its main role is with electronic interlock, buffer room personnel or materials from the clean area into the clean area of the inevitable passage, The pressure increases in a gradient from the outside (unclean area) to the inside (clean area).

The role of the buffer chamber has two, one is to prevent the air flow from the unclean area directly into the clean area, with a buffer chamber to greatly reduce this possibility. Two is the personnel or materials from the clean area into the clean area, in the buffer room there is a "shelved" for self-cleaning (mainly materials), so as to avoid pollution to the clean area after entering the clean area.

Function of the air lock room: buffer room for maintaining air cleanliness and positive pressure control in the clean room. The chamber is usually located in two identical clean areas of different cleanliness, or between clean and unclean areas.

To prevent cross infection between different environments, the air pressure between the connected functions is negative pressure and completely discharged. The air lock room has two doors that can not be opened at the same time, which is to partition the air in two different clean environments and prevent polluted air from entering the clean area. The air lock room has air supply and no air supply. Strict requirements of the biological clean room of the air lock room, there are purification air conditioning.

The differences and common points between the air lock room and the buffer room are: the air lock room and the buffer room are to partition two areas and prevent direct communication between them; They all have air supply and exhaust, they all have full rows, the doors should be able to interlock, not open at the same time, and they all have self-cleaning function. Difference point: the general partition between the airlock is two different clean areas, it is negative pressure on the two areas, the main role is to prevent the cross-contamination of the two clean areas, the role is two-way; The buffer room is between the unclean area and the clean area. It is positive pressure on the unclean area and negative pressure on the clean area. The main function is to prevent the pollution of the unclean area on the clean area, and the effect is one-way.
