1. The electrical interlock device box is fully sealed and can be repaired online;
2. The airtight design can meet the sealing requirements of airtight laboratories.
The pass box is a purification device installed on the partition wall between clean areas of different levels and between clean areas and non-clean areas, used to transfer items between each other. The pass box is the most effective device to prevent pollution. Its feature is the double door interlocking, which effectively reduces the number of times staff members enter the clean room to transport items and prevents external air from entering the clean room. The complete set of equipment is economical and affordable, and is the best transfer device for the clean room. Thepass box is widely used in micro-technology, biological laboratories, pharmaceutical factories, hospitals, food processing industry, LCD, electronics factories and other places that require air purification.
1.Temperature and environmental adaptability of mechanical devices and rubber components: -40°C~+50°C;
2. Structural pressure resistance: ≥2500Pa;
3. Air tightness: Keep the inner cavity of the transfer window airtight at a pressure of -500Pa, with a leakage rate of <0.5%vol/h;
4. . Self-cleaning ability: After turning on the self-circulating fan, the cleanliness inside the transfer window can meet the Class A purification requirements;
5. Sterilization method: VHP sterilization can be performed on the internal space and internal items of the transfer window, and the sterilization effect can be verified;
6. Corrosion resistance: Made of high-quality stainless steel, resistant to disinfectants, detergents, acids, alkalis and other chemical reagents.
1. Strict material standards: It is made of high-quality stainless steel with a smooth surface. It is not only durable but also has strong corrosion resistance. It can maintain stable performance under various complex environmental conditions, and will not rust or deform after long-term use, which greatly reduces maintenance costs.
2. Excellent sealing performance: Equipped with advanced double-layer sealing design, it effectively prevents the invasion of external dust, bacteria and other pollutants, while preventing the leakage of internal clean air. Whether it is fine particles or potential harmful microorganisms, they can be firmly blocked outside the transfer window to ensure that the transferred items are always in a highly clean state.
3. Intelligent interlocking function: The transfer window has a reliable interlocking mechanism, and the doors on both sides cannot be opened at the same time. This design fundamentally eliminates the risk of cross-contamination and provides safety for the transfer of items between different clean areas. Only when one side door is completely closed can the other side door be opened, strictly controlling the flow direction of air and the transmission path of pollutants.
4. High-efficiency filtration system: The built-in high-efficiency air filter can quickly filter harmful substances such as tiny particles, bacteria and viruses in the air. The filtered air is extremely clean, creating a sterile and dust-free environment for the delivered items, which is particularly suitable for pharmaceutical, electronic, food and other industries with strict requirements on cleanliness.
5. Humanized design: Easy to operate and easy to use. The design of the transfer window fully considers the principles of ergonomics, and the opening and closing force of the door is moderate, which is convenient for operators to transfer items. At the same time, we also provide a variety of sizes and specifications to choose from to meet the personalized needs of different customers.
6. Reliable quality and stable performance: After strict quality testing and verification, our clean transfer window has excellent performance stability. Whether it is in long-term continuous operation or frequent use, it can always maintain efficient clean transfer function, providing continuous and reliable support for your production and experimental activities.
Its working principle is scientific and efficient. Through the double-layer sealing structure, it ensures that during the delivery of items, the entry of external pollutants and the outflow of internal clean air are minimized. On the one hand, the interlocking function of the transfer window ensures that the doors on both sides cannot be opened at the same time, effectively preventing the risk of cross-contamination. When one door is opened, the other door is automatically locked. Only after closing this side door can the other side door be opened. This rigorous design provides reliable protection for the clean environment.
