Air shower is a very common equipment in the clean room. Its function is to maintain the cleanliness level of the clean room as well as the access of employees go entering or exit the clean room. Air shower can reduce the operation cost of clean room and improve the qualified rate of products.We are a manufacturer of clean room air shower.The factory is located in Shenzhen, China, our production of air shower can meet the requirements of most industries, there are standard air shower versions and customized air shower versions, welcome to contact us.
Usually, air shower is sealed by two doors. Only one door can be opened at the same time when an employee passes through the air shower. If one door is open, the other door is closed. Since the pressure in the clean room is higher than the pressure in the unclean area, if both doors are opened at the same time, the clean air will flow to the unclean area, resulting in lower pressure in the clean room and lower cleanliness level. The two doors of the air shower room we provide cannot be opened at the same time, so that the air flow will not flow to the unclean area.
The clean room has a stainless steel nozzle that can be rotated. The air coming out of the nozzle is purified by a high efficiency HEPA filter, which is very clean air. This kind of high-speed air can blow away dust, smell and other pollution sources on the surface of staff garments. There are various design schemes for air shower nozzle system. The most common air shower is equipped with 28 nozzles, 12 on the left side, 12 on the right side, and 4 on the ceiling. The air speed from the nozzle can reach 25m/s, and the spraying time can be set from 0 seconds to 99 seconds, according to the needs of customers.
The material of air shower room mostly are stainless steel 304, SUS201 or paint cold plate steel, also have colour steel plate additionally.We do not recommend the use of color steel plate, because this material is not durable for a long time usage, and it is easy to crack and break. If the air shower needs to be installed in a relatively humid place such as the clean room of the food industry, then stainless steel 304 is a good choice, because this kind of air shower has a good function of anti rust. SUS201 and paint cold plate steel is a more economical option, they also have a very good anti-rust function. The appearance of the paint cold plate steel is very elegant, pure white shell, very suitable for the clean room environment. The thickness of the shell is 0.8mm, 1.0mm and 1.2mm. The strength of 1.2mm is better, but the price is a little higher.The use of a thicker shell can effectively maintain the strength of the air shower, the surface is not easy to sag, after a long time of use can also maintain a good appearance.
The filter of air shower room is high efficiency filter and primary effect filter, the function of high efficiency HEPA filter is to remove the dust particles in the air, so that the clean grade reaches more than class 100, and then this kind of purified air is accelerated by the fan blowing to the staff. The high efficiency filter we provide is a mini pleated design, H13 efficiency, glassfiber filter paper as the material, which can be used for several years. If you need to change the HEPA filter, you can find a local dealer or you can directly contact us, we provide you with the standard HEPA filter.
The high velocity air flow from nozzle spray the surface of stuff garment, and finally the air flow will go into the exhaust return diffuser located on the air shower chamber bottom. The returned air flow will purified by HEPA filter again and accelerated by blower again. This is a cycle process, because the airflow has took along part of the dust pollution from employee garment surface, someone may think the airflow is not cleaned and should throw away, but when it comparing with the air from surrounding environment. The recycled airflow is much cleaner. This reuse reduces the burden on the hepa filter and extends its life.
As a professional air shower manufacturer, we will provide corresponding control panel. The language system of the control panel is Chinese or English. Through this panel, workers can control the wind speed of the motor in the air shower, which may directly lead to the change of the wind speed at the nozzle. The running time of the fan can also be controlled, and 0-99 seconds can be set. The initial value of our factory setting is 10s.You can also use this to control the lighting in the air shower. The function of voice prompt, when the employee enters the air shower room, the control panel has the function of voice prompt, which can guide the employee to do the correct operation, such as waiting for the air shower spray, rotating their body to ensure 360 degree all-round blowing, and finally prompt the employee when it`s the time to go out. Voice prompts are available in both Chinese and English.
No, if the employee enters the clean room from an unclean area, air shower blow is required. If the employee leaves the clean room and goes to the non-clean area, the air shower blow may not be necessary. If no blow when leaving the cleanroom, this can reduce the time for employees leaving cleanroom, improve work efficiency and reduce the power consumption of the air shower room.
We provide air shower to many place of the world. According to the long time of production and sales process, we found that the air shower door closer are more common vulnerability. A lot of air shower manufacturer not notice these, they will use some bad quality door closer in order to save cost. As a professional manufacturer, we always choose the good quality door closer, though this will cost a little more, but the service life of air shower door closer will increase longer.
Why the door closer so easy to break?
Because the air shower is used many times a day, many employees enter and exit the clean room from it. Closing and opening doors many times can easily lead to loss of door closer. It is necessary to use high-quality door closer. In the meantime, the quality of the door shell also needs to strengthen, use a bit thicker sheet metal, multilayer design also is one of our air shower`s characteristics.
