How does the air shower pass box achieve air transfer isolation?
How does the air shower pass box achieve air transfer isolation?As an efficient auxiliary purification equipment, the air shower pass box is inspired by the air shower room and can provide a local dust-free, sterile, and highly clean working environment. Sometimes it is also called a purification transfer box, an air shower transfer cabinet, or an air shower pass box. Whether it is medical, biopharmaceutical, electro-optical, chemical, food, precision instruments, or scientific research, these industries have special requirements for the working environment, and the air shower pass box can meet these needs. Zhongjing Purification not only manufactures transfer windows that meet standard specifications but also provides various styles of air shower transfer windows, including double-door air shower pass boxes, single-door pass boxes, etc. The company has rich experience in the production and operation technology of air shower pass boxes, which will be analyzed in detail below.Generally speaking, we will install air shower pass boxes at the door of clean rooms or rooms with different cleanliness levels. Its main function is to isolate indoor and outdoor airflow, prevent polluted air from invading the clean area, and avoid cross-contamination. The air used by the air shower pass box is mainly recycled. During the transfer of items, the air is first filtered through the primary filter and the primary filter. Then, the fan quickly blows out the filtered air, which is converted into clean air through the high-efficiency filter unit. Clean air is quickly ejected from the spherical nozzle, with an airflow speed of up to 20M/S, which can effectively and quickly remove dust particles on the surface of objects. At the same time, the air-carrying floating dust is re-inhaled into the primary filter to ensure continuous air purification. Special sealing strips are installed on the inner sides of the two side doors of the air shower pass box to ensure the air tightness of the pass box. The use process of the air shower pass box: 1. Open the outer door of the transfer window (the inner door of the transfer window is locked); 2. Place the items in the transfer window and then close the outer door of the transfer window; 3. Automatically start the air shower. When the system enters the shower process, the inner and outer doors are opened at the same time; 4. After a delay of 1 to 2 seconds, the fan starts to shower the items. The shower process lasts for about 10 seconds (can be set); 5. After the shower is completed, the fan stops and the inner and outer doors are closed at the same time; 6. After the air shower timing is completed, open the inner door to take out the dust-free and sterilized items (the outer door of the transfer window is locked). Then, there are many purification equipment used in the purification industry, and it is more critical to choose a suitable and high-quality air shower pass box. Usually, the conventionally produced air shower pass boxes have the following characteristics: 1. Air shower pass The box body can be made of two structural forms: colored steel and stainless steel. The surface is strictly degreased, de-rusted, and phosphate before being sprayed. It is strong and wear-resistant and has a beautiful appearance. 2. The fan uses a low-noise, high-pressure, and high-efficiency fan in combination with a time relay control system, which not only ensures the necessary wind speed but also saves power consumption; 3. The high-speed ball nozzle is scientifically and reasonably configured, and the wind speed at the nozzle outlet is as high as 20s or more, which can ensure the best air shower effect; 4. Equipped with ultraviolet sterilization lamps, it can achieve super purification, and ultraviolet sterilization, and prevent cross-infection, making this product safer and more Reliable; 5. The system is automatically controlled and operated and is equipped with a photoelectric sensor. The doors on both sides are equipped with mechanical or electronic interlocking devices to ensure that the doors on both sides cannot be opened at the same time to protect the safety of goods delivery; 6. It adopts a two-stage filtration system of primary and high efficiency, EVA sealing strip material, high sealing performance, and filtration efficiency of: 99.99%, ensuring the purification level; 7. It adopts imported electronic components and arc corners that are more suitable for the principle of clean rooms, with reliable performance; 8. According to customer requirements, a differential pressure gauge or an intercom can be installed on both sides of the box to make it convenient to take and deliver the box. Structural diagram: 1.
