As a special public space, hospitals have distinct standards for air cleanliness and microbial control in different areas due to varying medical treatment needs. Liquid tank air filters, with their zero-leakage sealing structure, ability to intercept particles ranging from 0.1 to 0.3μm, and wide environmental adaptability, have become the core components of air purification systems in high-cleanliness areas of hospitals. The following analyzes the application logic and practical value of key purification scenarios in hospitals. ​ I. Purification Area of the Operating Department: Building a Sterile “Air barrier” during the operation The operating department is the top priority in hospital infection control, especially for clean operating rooms, which need to simultaneously meet the three major requirements of “particle control”, “microbial interception” and “airflow stability”. The application of liquid bath air filters directly affects the incidence of surgical site infection (SSI). ​ Class I-II clean operating rooms (Class 100 / Class 1,000) : The “sterile defense line” for core surgeries Suitable scenarios: Cardiac surgery (cardiopulmonary bypass surgery), neurosurgery (intracranial tumor resection), organ transplantation (liver/kidney transplantation), orthopedics (joint replacement surgery), and other surgeries that require an extremely sterile environment. For this type of surgery, the concentration of 0.5μm particles in the surgical

Among numerous air purification devices, liquid tank high-efficiency filters, with their unique structure and working principle, have become key equipment for ensuring a highly clean environment. The following is a detailed introduction to its core functions and advantages for you. I. Core Role Precision particle interception: The liquid tank high-efficiency filter uses advanced filter materials such as ultra-fine glass fiber filter paper or polytetrafluoroethylene (PTFE)-coated materials. PTFE is a synthetic fluoropolymer known for its chemical resistance. These materials can precisely capture particles with diameters between 0.1 and 0.3 micrometers (μm) through three mechanisms: inertial collision (particles moving along the airflow path hit the filter fibers), interception (particles following airflow lines come into contact with fibers), and diffusion adsorption (very small particles move randomly and stick to fibers). At the rated air volume, the filtration efficiency for the most easily penetrating particle size (MPPS)—the size of particle that is most difficult to capture—exceeds 99.9995%, which is significantly higher than the standard for high-efficiency particulate air (HEPA) filters. This high efficiency removes small dust, smoke, and other particles, providing clean air for highly controlled environments like semiconductor manufacturing workshops and photoelectric clean rooms. As a result, product defects and malfunctions caused by

As the core “dust-proof checkpoint” of the clean area, the goods shower room is mainly used to remove dust particles adhering to the surface of goods when they enter and exit the clean room, preventing non-clean air from entering along with the goods. Therefore, it is widely used in industries with strict standards for the cleanliness of the production/operation environment. The following are its core application industries and specific scenarios, which are elaborated in combination with the characteristics of clean requirements in each industry: 1. Pharmaceutical industry (the most stringent application) The cleanliness requirements in the pharmaceutical industry are directly related to the safety and efficacy of drugs. Whether it is the production of active pharmaceutical ingredients, the processing of preparations, or the assembly of medical devices, it is necessary to strictly control contaminants such as microorganisms and dust. The air shower is an essential purification device. Specific scene Pharmaceutical production workshops (such as tablet, injection, and vaccine workshops): When raw materials (such as pharmaceutical powder and excipients), semi-finished products/finished products (such as medicine bottles and aluminum-plastic packaging) enter and exit the clean area (usually a 10,000-level or 100,000-level clean area), they need to pass through the material shower room

The rapid rolling shutter door air shower is a key device in clean workshops, logistics channels, and other scenarios, which has both rapid isolation and dust removal functions for goods. Its daily maintenance directly affects the cleaning effect, equipment lifespan, and operational safety. Maintenance should be carried out around the four core modules of “rolling shutter door System”, “air shower dust removal system”, “Electrical control system”, and “structural and safety components”. The specific precautions are as follows: I. Maintenance of Roller Shutter Door System: Ensure smooth opening and closing, as well as sealing performance Rolling shutter doors are the “core channel components” of the equipment. Special attention should be paid to the mechanical transmission and the condition of the curtain fabric to avoid problems such as jamming and air leakage. Clean the curtain fabric regularly to prevent the accumulation of stains Every week, wipe the surface of the curtain fabric with a neutral cleaner (such as a diluted dishwashing liquid) and a soft cloth to remove dust, oil stains, or sticky substances remaining from the goods (such as adhesive marks from packaging tape). Do not use strong acids, strong alkalis, or sharp tools (such as steel wool balls) for cleaning

The rapid rolling shutter door cargo air shower is a dedicated device that combines the efficient passage characteristics of the rapid rolling shutter door with the dust removal and purification function of the cargo air shower. Its core function is to quickly isolate the air circulation between the clean area and the non-clean area when goods enter and exit the clean area, and remove the dust, hair, and other contaminants adhering to the surface of the goods through high-pressure air flow, while reducing the waiting time of personnel and improving the efficiency of goods transfer. Its application fields are highly concentrated in scenarios with strict cleanliness requirements and frequent goods turnover. Specifically, it can be classified into the following categories: I. Food and Pharmaceutical Industry (Core Application Fields) The food and pharmaceutical industries have mandatory standards for the cleanliness of the production environment (such as microorganisms, dust, and foreign objects), such as food GMP and drug GMP. The rapid rolling shutter door material shower room can prevent goods from carrying contaminants into the core area, ensuring the safety and compliance of products. Food processing/packaging field Application scenarios: baking workshops, dairy product production lines, meat processing areas, beverage filling workshops, aseptic

In the field of special manufacturing, the core value of fiberglass bag air filters lies in their ability to meet high cleanliness requirements, withstand specific environments (such as local high temperatures and low corrosion), and ensure product accuracy and production compliance through “medium-efficiency filtration” or “pre-protection of high-efficiency filters”. They are particularly suitable for manufacturing scenarios that are sensitive to dust and impurities and require stable filtration performance. The specific application scenarios can be further classified into the following four categories, covering key fields such as electronic semiconductors, pharmaceuticals and food, aerospace, and optical instruments: I. Electronics and Semiconductor Manufacturing: Ensuring precise manufacturing processes and avoiding dust-induced waste The manufacturing of electronic semiconductors has extremely high requirements for air cleanliness (control of dust at the micrometer or even nanometer level). Fiberglass bag filters, with their low dust generation and medium to high efficiency filtration accuracy, have become the core filtration unit, directly affecting the yield of chips and components. Core chip manufacturing processes (photolithography/etching/deposition Scene requirement: During the photolithography process, if dust particles larger than 0.5μm adhere to the surface of the chip wafer, it will directly cause the photolithography pattern to shift and short circuit. During etching/deposition (such as

Glass fiber bag air filters (also known as glass fiber bag filters) take glass fiber filter material as the core and have the advantages of high temperature resistance, chemical corrosion resistance, high filtration accuracy (mainly medium and high efficiency levels), and large dust holding capacity. They are mainly used in “medium efficiency filtration” or “pre-protection for high efficiency filtration” scenarios in air purification. It is especially suitable for environments with high temperatures, corrosive gases or high cleanliness requirements. Its core application fields can be classified into three major dimensions: “industrial production”, “special manufacturing”, and “public and civilian”, as follows: I. Industrial production field: Withstand harsh environments and ensure compliance with equipment and emissions In industrial scenarios, the core value of fiberglass bag filters lies in achieving efficient filtration and equipment protection in high-temperature, corrosive or high-dust environments, preventing dust from affecting production or exceeding emission standards. Typical applications include: Energy and Power Industry (High-temperature Flue Gas Filtration) Thermal power plants/waste incineration plants: Flue gas filtration at the tail end of boilers and after the denitration system (SCR). Glass fiber can withstand temperatures up to 250-300℃ (with some special models having even higher temperatures), which can intercept fly ash and unburned

Flat plate air filters, with their simple structure, low cost and strong adaptability, are widely used in the “pre-filtration” or “primary filtration” scenarios of air purification. Some medium and high-efficiency models can also be used for specific mid-range purification needs. The core application fields can be classified into three major categories: “civil buildings”, “industrial production” and “special scenarios”, as follows: I. Civil Buildings and Public Spaces: Ensuring Indoor air quality The core demand of such scenarios is to filter out large particles such as suspended dust, hair, and pollen in the air, protect the air conditioning and ventilation system, and improve indoor comfort at the same time. Common application scenarios include: Office and commercial Spaces: Central air conditioning fresh air systems for office buildings, commercial buildings, shopping malls, supermarkets, hotel lobbies, etc. As a pre-filtering device, it can intercept dust, poplar catkins and other substances in the outdoor fresh air, prevent the accumulation of dust and the breeding of bacteria inside the air conditioner, and extend the service life of core components such as fans and coil units. Medical and educational facilities: hospital outpatient halls, corridors of inpatient departments, school classrooms, libraries, etc. It is necessary to filter out dust

The cleaning and maintenance cycle of flat air filters is not fixed and uniform. It needs to be comprehensively judged based on three core factors: the type of filter material, the dust concentration in the usage environment, and the actual resistance change. The following are specific standards and operation suggestions: To discuss cleaning cycles, it is important to note that this applies only to “washable filter materials” as outlined below. Flat plate filters are classified into “washable” and “one-time non-washable” media. For washable filter media, the cleaning cycle must be clearly defined. For one-time filter media (such as some paper filter media and low dust-holding capacity glass fiber filter media), they can be directly replaced when clogged without cleaning. 1. Applicable types of washable filter media The mainstream is polyester synthetic fiber filter media (such as spunbonded polyester and needle-punched polyester). These filter media have high fluveness, are resistant to water and weak alkali, and their filtration performance can be restored by 70% to 90% after cleaning. Usually, they can be washed 2 to 3 times repeatedly. A few nylon mesh filter materials (used for coarse filtration, such as intercepting large particles of dust and hair) can also be cleaned

The maintenance and upkeep cycle of the air shower transfer window should be comprehensively determined based on factors such as usage frequency, application scenarios (such as cleanliness level requirements), and the degree of environmental pollution. The core objective is to ensure its air shower purification effect, sealing performance, and equipment stability, and to prevent cross-contamination in the clean area due to improper maintenance. The following are the industry-wide standards for maintenance and servicing cycles and their specific contents, which can be adjusted according to actual circumstances I. Daily Maintenance (Daily/After Each Use) Frequency: Once before starting work daily + after each use (if the usage frequency is high, such as in the pharmaceutical or semiconductor industries) Core objective: Timely remove surface contaminants to ensure normal basic functions, suitable for all application scenarios (such as food, electronics, medical care). Specific content Appearance and cleaning: Use a clean cloth dipped in neutral detergent (avoid corrosive reagents) to wipe the inner and outer surfaces of the transfer window and the observation window glass to remove dust, stains or residual materials, and prevent dust accumulation and bacterial growth. Sealing performance inspection: After closing the transfer window door, observe whether the sealing rubber strips between

The air shower transfer window is a purification device that combines the functions of air shower dust removal and item transfer. Its core function is to remove the dust particles adhering to the surface of the items through high-speed clean air flow when transferring items between the clean area and the non-clean area (or areas of different cleanliness grades), prevent cross-contamination, and at the same time avoid the disruption of the air pressure balance in the clean area during the transfer process. Its application fields are highly concentrated in industries with strict requirements for cleanliness, sterility and dust control, and can be specifically classified into the following categories: I. Biomedical and Medical Device Industry The control of microorganisms, dust and foreign objects in this industry is directly related to product safety (such as the purity of drugs and the sterility of instruments), and it is one of the core application scenarios of air shower transfer Windows In the field of pharmaceutical production: It is used for material transfer in raw material drug workshops, preparation workshops (such as injections, oral solid dosage forms), and biopharmaceutical workshops (such as vaccine and antibody production). For instance, before transferring externally purchased auxiliary materials and
