Why do clean rooms need to install air showers and transfer windows?Air shower transfer window, why do clean rooms need to install air shower rooms and transfer windows? A general air shower room is a special channel specially set up for workers and materials to enter the clean room. The purpose is to reduce the dust and bacteria brought in when workers and materials enter the clean room, and at the same time, it serves as a sealed clean room in the airlock chamber. Installed between the clean room and the non-clean room, it is the necessary passage to enter the clean room.The air shower first uses a high-efficiency air filter to filter the airflow, and then sprays it on the staff and the material from different directions through rotating nozzles, thereby removing and reducing dust particles on the surface of people and materials, and then with The dusty air passes through the primary and high-efficiency air filters and circulates again. The overall design of the air shower room combines dynamic fluidics. It has a fully automatic infrared induction shower, and the entire process is operated with humanized voice prompts. Double-door interlocking is used, and the door cannot be opened or left at the same time. When the air shower is working, the double doors must be closed tightly to perform forced showering. The equipment in the air shower room is generally a pre-filter, main filter, air jet, and air blower. The filtration efficiency of the pre-filter is about 15%. It is mainly used to remove relatively coarse dust particles, and this filtering device can be washed with water or a vacuum cleaner; the main filter is mainly used to filter dust above 0.3um, which is a filtration efficiency of more than 99.99%, but this kind of The filter equipment part is very fragile, so when it becomes clogged, it needs to be reprocessed; the air jet is mainly used to remove dust particles attached to the human body, and the effect to be achieved is to peel off the particles; the blower is mainly used to circulate the air cleanly. Generally, the air shower is installed at the entrance of a clean room or sterile room. Generally, the maintenance of the devices in the air shower requires cleaning within a certain period according to the situation. For the pre-filter, it can be cleaned with water or vacuum dust cleaning. It is normally replaced every three months. The main filter should be tested 2 to 4 times a year. The clean workshop should be determined based on the wind speed value or pressure measurement value. Should the device be replaced? The stainless steel transfer window is an auxiliary equipment for clean rooms. The clean transfer window is mainly used for the transfer of small items between clean rooms. Between non-clean rooms and clean rooms, reduce the number of door openings and minimize the objective existence or damage to the clean room. The pollution in the clean area is reduced to a minimum. Standard stainless steel pass-through window features: 1. The stainless steel transfer window wall and door are made of sanded or mirror-polished stainless steel and the inner tank is made of stainless steel; 2. Stainless steel transfer window mechanical interlocking or electronic interlocking device, only one door can be opened at the same time; Optional accessories for stainless steel pass-through windows: 1. Ultraviolet germicidal lamp 2. Fluorescent lamp Features of air shower stainless steel transfer window: 1. The stainless steel transfer window adopts an electronic interlocking or mechanical interlocking device. The stainless steel transfer window can only open one door at the same time; 2. The stainless steel transfer window box and inner wall are made of stainless steel; 3. The stainless steel transfer window is equipped with 4 multi-angle adjustable stainless steel nozzles. The stainless steel transfer window uses top blowing. The stainless steel transfer window is equipped with a large air volume and low-noise fan. The voltage: 380V 50HZ can make the wind speed of the stainless steel transfer window greater than 25m/ s; 4. The stainless steel transfer window is equipped with a partition high-efficiency filter. The filtration efficiency of the stainless steel transfer window is 99.99%@0.5um, ensuring the purification level; 5. The stainless steel transfer window adopts an infrared induction shower; Air shower classification: It is generally divided into eight types: stainless steel air shower, three-blow air shower, corner air shower, explosion-proof air shower, automatic door air shower, single blow, double blow, and vertical flow air shower. The automatic door air shower is the only way for people to enter the clean room. It can more effectively reduce the bacteria and contamination problems caused by people entering and leaving the clean room. The door is electronically interlocked and can double as an airlock to prevent unpurified air from entering the clean room. The air shower filter is also equipped with a primary filter and a high-efficiency filter with partitions for secondary filtration to ensure a static upgrade of purification. Moreover, this product is manufactured after passing the U.S. standard verification, and its reliability is relatively high. |
