The difference between air shower room and buffer room, air lock room (air shower room, air disinfection room)

The air shower room is also called the air shower room, the air shower door, the air shower machine, the air shower room, the dust bathroom, the air disinfection room and so on. The air shower room is mainly composed of several large components such as fans, high-efficiency filters, control circuits, and boxes. The air shower room is necessary purification equipment for the entrance of the clean room. Its main function is to remove the dust from the human body by blowing showers. To achieve the purpose of purification, as long as the wind is sufficient, most of the dust on the human body can be removed. Of course, this is only one of the functions of the air 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, filtering and blowing.

Buffer room: The structure of the buffer room is roughly the same as that of the air shower room, which is mainly reflected in the composition of the inner and outer boxes, and the size and space. The main control system, purification filter and fan, its main function is to have an electronic interlock, the inevitable passage for the buffer room personnel or materials to enter the clean area from the unclean area, and the air pressure is from the outside (unclean area) to the inside ( clean area) with increasing gradient.

There are two functions of the buffer room. One is to prevent the airflow in the non-clean area from directly entering the clean area. With a buffer room, this possibility is greatly reduced.

The second is that when personnel or materials enter the clean area from the non-clean area, there is a "shelf" in the buffer room for self-cleaning (mainly materials), so as to avoid pollution to the clean area after entering the clean area.

The function of the airlock room: a buffer room set up to maintain the air cleanliness and positive pressure control in the clean room. The airlock room is usually set in two identical clean areas with different cleanliness, or between the clean area and the non-clean area.

To prevent cross-infection between different environments, the air lock chamber has a negative pressure for the air pressure between the connected functions and is fully exhausted. The air lock chamber has two doors that cannot be opened at the same time, the purpose of which is to separate two different clean environments. To prevent polluted air from entering the clean area, the airlock room is divided into air supply and non-air supply. The airlock room of the biological clean room with strict requirements has a purified air conditioner to supply air.

Difference between airlock and buffer:

Common point: the air lock room and the buffer room are to separate the two areas and prevent them from being directly connected; they both have air supply and exhaust, and they are all exhausted. The doors should be able to interlock and cannot be opened at the same time. Function.

The difference: the airlock generally separates two different clean areas, which are negative pressure for both areas, the main function is to prevent cross-contamination between the two clean areas, and the function is bidirectional;

The buffer room is between the non-clean area and the clean area. It is positive pressure for the non-clean area and negative pressure for the clean area. The main function is to prevent the pollution of the clean area from the non-clean area, and the function is one-way.

DOUBLE AIR-SHOWER

The air shower room is a highly versatile local purification equipment that is used to blow off the dust attached to the surface of the human body and the carried items that enter the purification area, and at the same time can act as an air lock to prevent unpurified air from entering the clean area.

The air shower room has air shower series for human use and wide channel air shower series for objects; the blowing method includes single-side blowing, double-side blowing, top blowing and other combinations; the air shower door includes a manual door, automatic sliding door and Various options such as interlocking. Material choices are: steel plate spray and stainless steel.

working principle:

The clean air flow filtered by the high-efficiency filter is sprayed on the person from all directions by the rotatable nozzle, thereby effectively and quickly removing dust particles. The cleaned dust particles are filtered through primary and high-efficiency filters and recirculated to the air shower area.

basic configuration:

1. Material of the air shower room: The outer box and inner wall are made of high-quality cold plate spraying or stainless steel, which has the effect of anti-corrosion and anti-rust.

2. Purification level: static 1000 level.

3. Double-layer filtration system: adopts plate-type primary filter and partition-type high-efficiency filter to ensure the purification level.

4. Advanced programming circuit control, automatic infrared induction blowing.

5. Adjustable stainless steel nozzles are durable; the handle and floor of the air shower room are made of wear-resistant and easy-to-clean stainless steel plates.

6. Use a dedicated fan for high air volume and low noise air shower room.

7. Various non-standard air shower sizes can be customized according to different site sizes, and the finished products can be assembled and transported.

Optional accessories:

1. Access control system, 2. Automatic door system, 3. Ultra high efficiency filter, 4. Anti-static device, 5. Self-cleaning function, 6. Door opening delay
