1. What is a laminar air flow unit? Laminar air flow unit is also called a laminar flow hood, laminar flow cabinet or compounding hood. Laminar flow hood is an air purification equipment that provides Class A unidirectional flow and creates a local high cleanliness environment.   2. Why do we need a laminar air flow unit? Laminar flow hood is one of the equipment that can shield and isolate operators from products. Its main purpose is to avoid product contamination. It is an ideal equipment for achieving high purification level requirements in low purification areas.  It is mainly used to protect the production process of sterile drugs.   3. What is the structure? It is mainly composed of the tank, fan, high-efficiency air filter, homogeneous membrane, lighting fixture, etc. Structure Diagram   4. What is the working principle? After passing through HEPA at a certain air velocity, the air is equalized by the homogeneous membrane, so that the clean air flow is sent to the working area in an unidirectional flow. It is generally installed above the working area, and the air in the working area is replaced by clean air in a vertical unidirectional flow. Local micro positive pressure is formed in the working area, which can effectively prevent the air flow in the background area from penetrating. Air Flow Diagram   5. Characteristics & Features It can be used alone or in combination. Double layer negative pressure structure, no leakage risk. HEPA ensures low resistance and high efficiency, and the liquid tank seal is more reliable. The inside and outside are consistent, clean and free of dead ends. Various forms of control to meet different requirements of customers. Multiple pressure equalizing, uniform air velocity and good unidirectional flow pattern. Imported fan, large residual pressure, low noise, energy saving, reliable performance. The design is simple, the maintenance cost is low, and the efficient Class A clean environment is provided. It can be used in the assembly, testing, inspection and other production processes of sterile products requiring ultra clean. Integrated fan filter module, low noise. 6. Main technical parameters Cleanliness class: Class A Rated air velocity: Noise: 65~75dB Air return type: side or top air return type Control mode: touch screen control, remote control+panel control Power supply: 220V 50HZ or customized Standard model and size: https://www.wxljjh.com/product/jinghuashebei/cengliuzhao, or designed and manufactured according to the customer’s URS. 7. Application It is widely used in electronics, pharmaceutical, chemicals, science and technology, bioengineering and other industries. It is widely used in the safe washing, drying, filling and sealing lines of precision electronic device operation rooms and pharmaceutical workshops, antibiotic bottle washing, drying, filling and sealing lines, oral liquid bottle washing, drying, filling and sealing lines, and clean air supply treatment on large infusion production lines.   8. Project case Pharmaceutical Project (side air return type):   Filling line (top air return type):   9. Notices It should be installed under Class D or higher working conditions. The background area shall be cleaned 5 minutes in advance to make the cleanliness meet the process requirements. It is forbidden to place unnecessary articles in the working area and try to avoid actions that obviously disturb the airflow.   As the ONE-STOP Solutions Provider, we have rich experience and matured professional team, if you have any question about filtration and purification, welcome to send inquiry to us.

1. Civil Use and Industrial Use Air Filter: Civil use: Household air purifier, automobile air conditioning filter; Main material PP, PP / PET composites; Filtration efficiency, E12 or lower. Industrial use: For clean room (primary, middle and high efficiency); For HVAC system in public places ((primary and middle efficiency); For engine protection (primary efficiency, cotton / wood pulp, generally cartridge type) For air intake filtration of air compressor 2. Can the air filter be cleaned? The air filter cleaning mentioned by the customer is generally aimed at the primary and medium efficiency air filter, not the high efficiency air filter; The main reasons are poor air quality, short service life of the air filter and high operating cost; Filter cleaning is not recommended; After cleaning, the static electricity completely disappears and the filtration efficiency is low; During the cleaning process, the filter material structure will change and the filtration efficiency will be reduced; After cleaning, particulate matter remains on the air inlet and outlet surfaces, increasing the load of the post air filter; If the air filter is damaged during cleaning, especially if it is invisible to the naked eye, it will cause leakage and affect the post air filter.   3. Reasons for sudden shortening of filter service life The resistance value of a normally used air filter will not change suddenly, which is generally caused by changes in the external environment; The content of particulate matter in the fresh air increases, such as the frequent occurrence of haze in winter and willow catkins in spring; In winter, especially in Northeast China, there is rain and snow on the air filter surface, causing the air filter to be blocked; The content of particulate matter in the return air increases, such as the change of production process, the increase of production frequency and the increase of personnel activities; Damage of wet and hot elements and disinfectants to the air filter; Customers pay more attention to seasonal changes in the process of use, and daily data record accumulation can provide basic support for air filter replacement. 4. How to judge the air inlet and outlet surfaces? It cannot be judged simply by the position of the sealing strip. Some of the sealing strips are on the air inlet surface and some are on the air outlet surface, depending on the installation form of the air filter inside the equipment. For the liquid tank filter, it relies on gel sealing, and the gel surface is the air inlet surface. For filters without partition and with partition, the air outlet surface is generally the surface whose frame is leveled with the filter surface. 5. Advantages and disadvantages of glass fiber (GF) filter material and polytetrafluoroethylene (PTFE) filter material of high efficiency air filter GF: Long term use in clean industry, good filtration effect and stable performance; Large dust capacity and long service life. The electronic industry is super efficient and can be used for 30 years; Inorganic materials, low TVOC content; Applicable to aerosol test leakage point; High gram weight and high resistance value; Not resistant to HF (hydrofluoric acid). PTFE: Stretch film, low thickness, need to rely on the support layer for molding; Small dust capacity and unstable service life; High TVOC content; Not applicable to aerosol test leakage point (causing membrane hole blockage); Low resistance value, about half of GF; Good chemical stability and wider application range.   6. How can we control the quality of air filters?   We have equipped with German TOPAS testing lines, to test the air volume, resistance and efficiency of the filter comprehensively so as to ensure the excellent quality of air filters from LENGE. Detailed testing items are as below: - TOPAS ALF114 testing line for primary and medium efficiency air filters: Air volume - resistance Initial efficiency DHC EN 779 ASHRAE 52.2 - TOPAS AFS150 testing line for high efficiency air filters: Air volume - resistance Local efficiency Overall efficiency W-type high efficiency and inspectability MPPS   As the ONE-STOP Solutions Provider, we have rich experience and matured professional team, if you have any question about filtration and purification, welcome to send inquiry to us.
