quality Cleanroom Air Shower & Stainless Steel Air Shower factory

Application of Stainless steel air shower   The air shower is a cleaning equipment for modern industrial clean workshops, which can remove dust on the surface of people, buffer and isolate the clean and non-clean areas on both sides of the air shower. The equipment is widely used in the fields of food, medicine, bioengineering and precision electronics. Most of the air showers are similar now, but they are divided into many types, such as stainless steel air showers, color steel air showers, and cold-rolled sheet air showers.     The stainless steel air shower is divided into ordinary type and interlocking type: the ordinary type adopts manual start blowing control, and the interlocking type is added with linkage interlock, which provides a guarantee for better blowing. When the staff enters the air shower, after the door is closed, it will automatically blow the shower. At this time, the doors on both sides are in a locked state, and can not be opened until the blowing is completed. With this control method, a process that must be sprayed is completed. It ensures that the clean area is always in an ideal air clean condition.

The advantages of stainless steel air shower Our stainless steel air shower is a self-contained air re-circulation system designed for installation at the entrance to a clean room. These phone booth-like clean room entry systems utilize high-velocity air to purify personnel, equipment and materials entering the clean room.   When workers enter the air shower, the entrance door closes and a powerful airflow through the filter is blown towards the workers from multiple adjustable and precisely placed nozzles. These high-velocity airflows blow contaminants large and small from workers' clean room clothing. After the cycle is complete, the exit door opens and workers continue into the clean room.   Stainless steel air showers combine high-quality all-metal construction with high performance, custom options and versatile configurations. Excellent design advantages make these clean room air showers easy to install and maintain. Our stainless steel air showers provide maximum efficiency and value for your clean room or other controlled environment.  

How much do you know about the purification details of the clean room!   According to international practice, the dust-free purification level is mainly specified according to the number of particles in the air whose diameter is larger than the classification standard per cubic meter. That is to say, the so-called dust-free is not 100% without a little dust, but controlled in a very small amount of units. Of course, the particles that meet the dust standard in this standard are very small compared to our common dust, but for optical structures, even a little dust will have a very large negative impact, so in the production of optical structure products , dust-free is an inevitable requirement. The number of particles with a particle size of less than 0.5 microns is controlled to less than 3,500 per cubic meter, which has reached the international dust-free standard A level. The dust-free standards currently used in chip-level production and processing have higher requirements for dust than Class A, and such high standards are mainly used in the production of some higher-level chips. The number of fine dust is strictly controlled within 1000 per cubic meter, which is commonly known as the 1K level in the industry.   The following are the purification parameters that the clean room needs to know: 1. Compartment, ceiling material, ceiling height; 2. Floor material; 3. Whether it is constant temperature and humidity; 4. Whether exhaust air is required; 5. The total number of people in the workshop; 6. The calorific value of the workshop process equipment;   And so on a series of parameters.   The standards for a class 100,000 clean room are:   Maximum allowable amount of dust (per cubic meter);   The number of particles greater than or equal to 0.5 microns shall not exceed 3,500,000, and the number of particles greater than or equal to 5 microns shall not exceed 20,000;   Maximum allowable number of microorganisms;   The number of bacteria shall not exceed 500 per cubic meter;   The number of settled bacteria should not exceed 10 per petri dish.   Pressure difference: The pressure difference between clean rooms of the same cleanliness level should be consistent. The pressure difference between adjacent clean rooms of different cleanliness levels should be ≥5Pa, and the pressure difference between clean rooms and non-clean rooms should be ≥10Pa.   When the 100,000-level dust-free workshop has no special requirements for temperature and humidity, it is appropriate to wear clean work clothes without feeling comfortable. The temperature is generally controlled at 20~22℃ in winter; 24~26℃ in summer; fluctuation ±2℃. The humidity of the clean room in winter is controlled at 30-50%, and the humidity in the clean room in summer is controlled at 50-70%.   Power distribution: The general illuminance value of the main production room in the dust-free workshop (area) should be ≥300Lx; the illuminance value of the auxiliary studio, personnel purification and material purification room, airlock room, corridor, etc. should be 200~300Lx. noise control 1. During the dynamic test, the noise level in the 10,000-class clean room should not exceed 70 dBA. 2. During the static test, the noise level of the 10,000-level turbulent clean room should not be greater than 60 dBA. airflow organization The main air supply method used in the 100,000-level dust-free workshop; 1. Partial orifice ceiling air supply; 2. High-efficiency air filter with diffuser plate for ceiling air supply; 3. Three types of air supply, including air supply on the upper side wall.   The main return air method used in the 100,000-level dust-free workshop 1. Arrange the return air outlet at the lower part of the single side wall; 2. When using the corridor return air, arrange the return air outlet evenly in the corridor or centrally set the return air outlet at the end of the corridor.   Air outlet velocity m/s:   1. Orifice 3~5 of the orifice plate，   2. Side air outlet:   (1) Attach jets 2 to 5，   (2) For non-attached jets, the return air at the lower part of the same side wall is 1.5~2.5, and the return air at the lower part of the opposite side wall is 1.0~1.5.   Return air velocity (m/s):   1. The return air outlet of the clean room is not more than 2,   2. The return air outlet in the corridor is not more than 4.   Standard operating procedures for personnel entering and leaving the 100,000-level dust-free workshop   1.

Common faults and how to deal with the fault of the air shower:    Common faults:   1.  the power switch, air shower usually have four places to cut off the power supply:   (1). air shower outdoor cabinet power switch;   (2) air shower indoor control panel box;   (3). air shower room on both sides of the outer box (here, the power switch to prevent emergency cut off the power, effectively improve our personal safety). When the power indicator fails, do not prevent re-check the above four air shower power at.   2. the air shower fan is not working, the first time to check the air shower cabinet emergency switch is cut off, as determined cut off, gently press the hand to the right to let go.   3. the air shower fan reversing or wind shower speed is very small, be sure to check the 380V three-phase four-wire line is reversed, the general factory installation will have someone to pick up a good line; such as the reverse of the air shower Light source will lead to air shower fan does not work or reverse air shower speed decreases, the weight will burn the entire air shower room circuit board; we do not care to change the wiring.   4. the air shower room is not blowing shower, in addition to the above three points, but also need to check the air shower cabinet emergency stop button is pressed, such as emergency stop button for the color, the air shower will not blow shower; Press the emergency button again to work properly.   5. the air shower can not automatically sense the air shower, check the air shower inside the lower right corner of the cabinet light perception system to see if the light sensing device is installed correctly, such as the light on both sides of the positive and light sense of normal, you can automatically sense the shower .   6. the use of air shower room for a period of time when the wind speed is low, please check the early air shower, high efficiency filter is too much dust, if so please replace the filter. (Air shower initial filter is generally replaced within 1-6 months, the Airshower high efficiency filter is generally replaced within 6-12 months)   How to deal with the problem of air shower:   1. When the use of air shower for a period of time, if the wind speed is very low, you should immediately check the air shower filter can dust too much, if the new change filter. Usually 1-6 months it is necessary to exchange once, high efficiency filter is usually 6-12 months to exchange once.   2. If the air shower can not be automatically sensed when the shower, check the air shower room light box bottom right sense of sensitivity system to see whether the device light sensitive equipment.   If the emergency stop button is red, the air shower will not blow shower, just press the emergency button can be normal operation.   3. When the air shower room is not working, the first check a disadvantage of the door outside the tank can switch emergency switch, if intercepted, quietly by hand press, turn right to let go.   4. Air shower fan reversing air shower may wind speed is very small, it is necessary to check the 380V three-phase four-wire line can be reversed. If the reverse of the air shower line source, the light will cause the air shower fan does not work or reverse the wind speed reduce the wind speed, the shower will burn the entire air shower circuit board.   How to maintain air shower:   1. regular use of equipment for measuring the technical indicators, such as does not meet the technical parameters of the request should be promptly addressed.   2. according to the actual use of regular early air filter filter removed.   3. when the wind speed becomes smaller, we should first check the primary effect of air filter surface is black, if the black is pre-filter to accommodate more dust, increased resistance, which should be removed early effect air filter within the non-woven Cloth to be cleaned or replaced.   4. when the replacement or cleaning of non-woven fabrics, still can not increase the air velocity is high efficiency air filter has been blocked, resulting in increased resistance, you should replace the high efficiency air filter.   5. when replacing the high efficiency filter, remove the blister board, remove the high efficiency filter, replace the new high efficiency air filter according to the original high efficiency filter specification model. The installation should confirm the arrow mark on the high-efficiency filter, the arrow should point to the direction of air flow. And to ensure a good seal to prevent leakage.   6. after the replacement of high efficiency filter need to confirm the border no leakage, and use the dust particle counter to detect, to achieve the technical indicators before normal work.   7. regular maintenance of the electrical circuit, if the fault can refer to the electrical schematic maintenance.   8. regular door enclosure, the electronic lock with its keyhole alignment, so as to avoid lock pin stuck.   9. the use of temperature shall not exceed 50 ℃, and the use of open flame is strictly prohibited.   Application of air shower   Air shower room is usually used in micro-electronics, optoelectronics, semiconductors, pharmaceuticals, food, chemicals, aviation, automotive, printing, laboratories and other clean room and non-dust-free workshop, ladder cleanliness workshop for low-cleanliness room Into the high cleanliness of the room to remove all parts of the body more than 0.3 micron dust particles, so as not to enter the clean room to bring pollution. But also play the role of airflow buffer, because in the process of opening the door, accompanied by the flow of air, the air shower good air flow parked inside the air shower, a good air flow to avoid the air pollution .
