Air filter classification and specification comparison table
Air filter classification and specification comparison tableThe air filter is mainly used to purify the intake air and remove dust particles. In addition, the exhaust gas from some production processes contains small pollutants (such as radioactive substances, oil mist, etc.). Although this type of purification belongs to exhaust purification, due to its high purification requirements, air filters are also required. An air filter refers to an air filtration device, generally used in clean workshops, clean factories, laboratories, and clean rooms, or for dust prevention in electronic machinery and communication equipment. It is divided into primary-efficiency filter, medium-efficiency filter, high-efficiency filter and sub-high-efficiency filter. Various models have different standards and performance capabilities. This article focuses on the main classifications and characteristics of air filters and a comparison table of efficiency specifications of junior high-efficiency filters.Primary air filter Purpose: filter section in general ventilation air handling equipment or primary filtration in fresh air systems. Features: The filter material can be replaced by yourself, and the initial effect of the paper frame is disposable. Foldable medium-efficiency air filter Purpose: Filtration of ventilation systems. General air purification in the fields of electronics, pharmaceuticals, mechanical instrumentation, metallurgy, petroleum, chemical industry, light industry, food, and other fields. Features: high efficiency, large dust holding capacity, small space occupation. Bag type medium efficiency air filter Usage: Central air conditioning centralized ventilation system, or as a pre-filter for high-efficiency filters. It can reduce the burden of high-efficiency filters and extend their service life. It can also be used for general air purification in the industrial field. Features: small resistance, large dust holding capacity. activated carbon filter Purpose: Effectively remove odors, volatile agents, bacteria, viruses, and various air pollutants, such as paint spray, smoke, common pollutants in electronic factories and museums, and odors from food processing plants and hospitals. Features: Highly developed microporous structure, high adsorption capacity, fast adsorption and desorption speed, and good purification effect. Pre-filtration is required when using activated carbon filtration, otherwise, the efficiency of activated carbon will be reduced due to other pollutants in the air. activated carbon filter Purpose: used as primary pre-filtration in ventilation and air conditioning systems with low air quality requirements, or places with harsh surrounding environments and high dust levels. Features: low resistance, easy to clean, and easy to maintain. Sub-high efficiency air filter Purpose: End-end filtration of various clean projects and central air-conditioning and process air supply systems with special requirements or clean room filtration. Features: high filtration efficiency, low resistance, large dust holding capacity. high-efficiency air filter Purpose: clean air conditioning system, high cleanliness environment. Features: high efficiency, low resistance. Aluminum mesh air filter Purpose: Used as primary pre-filtration in ventilation and air conditioning systems with low air quality requirements, or places with harsh surroundings, dust, and grease. Features: Durable and easy to clean. High-efficiency air filtration unit with fan Usage: Suitable for sterile operating rooms in hospitals and manufacturing fields such as electronics, biology, medicine, and food. Features: Suspended under the floor, the cleaning effect can reach 10,000 or 100,000 or 100,000 levels, saving space in the machine room. It is suitable for local purification, especially in environments where floors are often washed in the food industry. High air volume high-efficiency filter Purpose: high-performance filter at the end of the air conditioning box Features: High filtration efficiency, large air volume, and large dust-holding capacity. High-efficiency air filter air outlet Purpose: Suitable for clean rooms with various cleanliness levels and various ceiling structures in the form of non-laminar flow. Features: reliable performance, easy installation and disassembly, simple maintenance |
