All-round introduction of medium-effect air filters
All-round introduction of medium-effect air filtersThe medium-effect air filter is mainly used in central air-conditioning and centralized air supply systems. It can be used in the primary filtration of air-conditioning systems to protect the next level of filters in the system and the system itself. In places where the requirements for air purification and cleanliness are not strict, the air processed by the medium-effect air filter can be sent directly to the user. Medium-effect air filters are widely used in central air-conditioning ventilation systems, pharmaceuticals, hospitals, electronics, food, and other industrial purification, medium-effect air filters can also be used as the front-end filtration of high-efficiency air filters to reduce the load of high-efficiency air filters and extend their service life.In life, we often hear about medium-efficiency air filters, so what is a medium-efficiency air filter? As the name suggests, the medium-effect air filter is also a kind of air filter, here to lets you understand all aspects of this product. Is the main production and sales: filter, Shenzhen filter, air filter, air filter, primary filter, primary nylon mesh filter, primary air filter, intermediate filter, intermediate air filter, high-efficiency filters, high-efficiency air filters, aluminum mesh filter, primary activated carbon filter, high-temperature-resistant primary filters, bag filters, box filters, FFU air filtration unit. Professional manufacturer of air purification equipment, etc. Medium efficiency filter, made of man-made fiber and galvanized iron. Various efficiencies are available, including 40-45%, 60-65%, 80-85%, 90-95%. The flange consists of 26 gauge galvanized iron. This series of products can be used in industrial, commercial, hospitals, schools, buildings, and other factory air-conditioning equipment, but also can be installed in the gas turbine air inlet equipment or computer room, to extend the service life of the equipment. 一. Key points of product selection 1. The main control parameters for the selection of medium-effect air filters are rated air volume, filtration efficiency under rated air volume, initial resistance under rated air volume, dust capacity, and external dimensions, etc. 2. 2. according to JG/T22-1999 "general ventilation air filter performance test methods" the method of inspection, the particle size ≥ 1.0μm particles of atmospheric dust counting efficiency ≥ 20% and <70% of the filter for the medium-effect air filter. 3. Commonly used filter materials for medium-effect air filters are glass fiber, non-woven fabric, etc. 4. 4. The manufacturer should provide the dust capacity of the filter. 5 The initial resistance of the medium-effect air filter should be ≤80 Pa. When designing, the final resistance can be two times of the initial resistance as the calculated resistance of the filter. 6 The initial resistance of the filter should not be more than 80 Pa. 6. The initial resistance of the filter shall not exceed 10% of the resistance of the product sample. After the regeneration and cleaning of renewable or washable filter media, the efficiency shall be not less than 85% of the original index, and the resistance shall not be higher than 115% of the original index. 7. The air filter should meet the requirements of fire protection, and the flash point of the paint of the air filter should be not less than 163℃. 8. The medium-effect air filter should not be used independently and should be used in combination with the coarse-effect air filter. Construction and installation points The air filter should be avoided to be installed directly on the downwind side of the shower room and humidifier, and effective measures should be taken when it is impossible to avoid. Relevant standard atlas 07K505 Design and Installation of Clean Surgical Department and Medical Gas Fourth, the implementation of standards Product standard GB/T14295-93 Air Filter ? JG/T22-1999 "Performance Test Methods for Air Filters for General Ventilation". Engineering Standard GB50073-2001 "Design Code for Clean Plants". GB50333-2002 Technical Specification for the Construction of Clean Surgical Departments in Hospitals Industrial Application It is mainly used in the intermediate filtration of central air-conditioning ventilation systems, pharmaceuticals, hospitals, electronics, food, and other industrial purification; It can also be used as the front-end filtration of high-efficiency filtration to reduce the load of high-efficiency filtration and prolong its service life; Due to the large windward surface, it has a large dust volume and low wind speed and is considered to be the best medium-effect filter structure at present. |
