The automatic lifting transfer window is mainly applied in fields where there are strict requirements for air cleanliness, sterility, or isolation of material transfer. Its core function is to transfer materials between areas of different cleanliness grades or isolation areas while blocking cross-contamination of air. I. Biomedical Field This is the core application scenario of the automatic lifting transfer window, which is directly related to the quality of drug production and personnel safety. Pharmaceutical production workshop: It is used for the transfer of raw materials, semi-finished products, or packaging materials between workshops of different cleanliness levels (such as 10,000 grade and 100,000 grade), to prevent the disruption of the air pressure balance and sterile environment in the clean area during manual transfer. Biological laboratory: In a microbiology laboratory, PCR laboratory, or biosafety laboratory, transfer experimental samples, reagents, or consumables to prevent sample contamination or leakage of harmful microorganisms. Hospital clean areas: such as operating rooms, ICUs, and sterile drug preparation rooms (PIVAS), where surgical instruments, sterile drugs, or patient supplies are transferred to reduce the risk of contamination caused by personnel entry and exit. II. Food and Cosmetics Sector It is mainly used to ensure the hygiene and safety during

The core of daily maintenance for the automatic lifting transfer window lies in regular cleaning, component inspection, and functional testing to ensure its sealing performance and normal lifting function, thereby avoiding cross-contamination. I. Daily Maintenance: Basic cleaning and function confirmation Basic checks should be completed before and after daily use, with a focus on ensuring immediate safety. Surface cleaning: Wipe the inner and outer surfaces of the transfer window, the observation window, and the control panel with neutral detergent to remove stains and dust. Corrosive solvents are prohibited to prevent damage to the surface or sealing strips. Functional test: Test the lifting function according to the normal operation process to confirm that the ascending and descending processes are smooth without any lag, and it can stop precisely after reaching the position without any abnormal noise. Door lock inspection: Check the interlocking function of both side doors to ensure that when one side door is opened, the other cannot be opened to prevent direct air circulation. Ii. Weekly Maintenance: In-depth inspection of key components Every week, a detailed inspection of the core components should be carried out to prevent potential faults. Sealing rubber strip inspection: Check whether the sealing rubber strips

The installation and maintenance of high-efficiency filters with separators should focus on two core aspects: sealing performance and filtration efficiency. Any improper operation may directly lead to excessive particles in the clean area. These two links are the key to ensuring the long-term effective operation of the filter. Installation determines the initial effect, while maintenance determines the long-term stability. The following lists the core precautions, respectively, from the aspects of installation and maintenance. I. Installation Precautions: Prevent initial leakage The core objective of the installation is to ensure that there are no leakage points between the filter and the installation frame or within the filter itself. Preparations before installation: Before installation, it is necessary to check whether the primary and medium-efficiency filters in the clean room have been replaced, and whether there is no dust or debris in the ventilation ducts to avoid subsequent contamination of the HEPA. At the same time, it is necessary to check whether the packaging of the HEPA is intact, whether the filter paper is damaged or deformed, and whether the sealing glue on the frame is uniform. Sealing treatment: Special sealing materials (such as polyurethane foam glue, sealing gaskets, and liquid tank glue) must

This question directly addresses the core components of clean workshop air purification systems. Its application value is mainly reflected in three scenarios. 1. Terminal air purification: Ensure the cleanliness of the core process area This is its main application form, which directly determines the final cleanliness level of the production environment. Installation location: It is usually used as the terminal supply air outlet of the clean room, such as the high-efficiency supply air outlet on the ceiling (HEPA is often integrated in the FFU, which stands for Fan Filter Unit, as well) or the side supply air outlet. Core function: Filter the air that has been pre-treated by primary and medium-efficiency filters, with a particle retention efficiency of over 99.97% for particles ≥0.3μm, ensuring that the air sent into the core process area is clean. Typical scenarios include photolithography areas in semiconductor chip manufacturing, aseptic filling areas in pharmaceutical production, and the protection of operating tables in biological laboratories. 2. Return air and exhaust air filtration: To prevent cross-contamination and environmental emissions In addition to supplying air, the use of HEPA in return air or exhaust air systems is equally crucial, mainly for pollution control. Return air filtration: It prevents

The daily maintenance and upkeep of air showers in food factories focus on ensuring that they continuously and stably blow clean air and efficiently remove contaminants, thereby avoiding the risk of contamination in the clean area due to equipment failure. Daily maintenance should revolve around the three core actions of “cleaning, inspection, and replacement”, and can be divided into daily, weekly, and monthly maintenance according to the cycle to ensure that all key components of the equipment are covered. I. Daily Maintenance: Basic cleaning and functional inspection It should be done before and after daily use. The key is to keep the inside and outside of the equipment clean and confirm that the core functions are normal. Clean the interior of the air shower: Use a clean cloth dipped in food-grade disinfectant to wipe the floor, inner walls, door body, and infrared sensor of the air shower to remove residual dust and stains. Check the air-blowing function: Start the air shower program and confirm that the air output from both nozzles is uniform, the wind force is strong, and there is no obvious abnormal noise or no air. Check the sealing performance of the door body: Close both doors of

In livestock farms, air filters are key equipment for controlling air quality, reducing the spread of diseases, and improving the breeding environment. Its core function is to filter out dust, microorganisms (including bacteria, viruses, and fungal spores), ammonia/hydrogen sulfide, and other harmful gases and odors in the air, thereby ensuring the health of livestock and poultry, improving production efficiency, and reducing pollution to the surrounding environment. According to the filtration objectives and technical principles, the commonly used air filters in livestock farms are mainly classified into the following categories: I. Classification by filtering object: Four core types Particulate matter filter (mainly for dust removal) It is mainly used to remove solid particles in the air, including feed dust, livestock and poultry dander, feathers, and dust raised after the drying of manure, among other substances. This type of dust not only irritates the respiratory tracts of livestock and poultry but also adsorbs microorganisms, becoming carriers of disease transmission. Common types Primary air filter Material: Non-woven fabric, nylon mesh, metal mesh, coarse fiber filter paper. Filtration efficiency: For large particles ≥5μm, the efficiency is approximately 30%-60% (by weight method). Application scenario: As a pre-filter, it protects the subsequent medium and high-efficiency filters

The semiconductor industry has extremely strict requirements for cleanrooms. The core objective is to control key parameters, including particles, temperature, humidity, airflow, pressure, and chemical contaminants, in order to prevent chip manufacturing defects (such as short circuits and decreased photolithography accuracy) caused by tiny impurities or environmental fluctuations.

A clean bench is a local air purification device that provides a sterile and dust-free clean environment for the operation area by filtering particles, microorganisms, and other pollutants in the air. Its application fields are extensive, covering industries with strict requirements for environmental cleanliness. Specifically, it can be divided into the following major categories: I. Biomedical and Life Sciences Field This field is the core application scenario of clean benches. The core requirement is to prevent microbial contamination of experimental samples/reagents while protecting operators from biological hazards (such as pathogenic bacteria and viruses). The main application scenarios include: Microbiology experiments: isolation, culture, and identification of bacteria, fungi, and viruses, as well as microbial counting and drug sensitivity tests, etc., to avoid contamination of the culture system by external miscellaneous bacteria and ensure the accuracy of experimental results. Cell biology research: Passage, cryopreservation, transfection of mammalian cells (such as HeLa cells, stem cells), as well as operations like apoptosis and cell cycle detection, to prevent cell contamination by mycoplasma, fungi, etc., and ensure the purity of the cell line. Molecular biology experiments: PCR amplification, gene cloning, plasmid extraction, nucleic acid electrophoresis, etc., to avoid cross-contamination of nucleic acids (such as exogenous

In fields with strict requirements for environmental cleanliness, such as microbiological experiments, biopharmaceutical production, electronic component manufacturing, and food processing, clean benches serve as a solid “protective shield”. With advanced technical principles and precise control capabilities, they provide safe, efficient, and stable clean Spaces for various critical operations. It becomes the core equipment for ensuring the accuracy of experimental results and the reliability of product quality. ​ I. Core Function: Build a sterile and dust-free operation, “Pure Land” The core mission of the clean bench is to thoroughly remove particles, microorganisms, and other contaminants from the operating area through scientific airflow organization and an air filtration system, achieving high cleanliness control of the local environment. Its working principle is centered around two key links: “air purification” and “air flow stabilization”. High-efficiency air filtration system: The equipment is equipped with an internal primary filter and a high-efficiency air filter (HEPA). The primary filter first intercepts large particles of dust, hair, and other impurities in the air, thereby extending the service life of the high-efficiency filter. HEPA filters can efficiently filter particles with a diameter of 0.3μm or more, achieving a filtration efficiency of over 99.97%. Even ultra-high-efficiency air filters (ULPA) can
