Introduction of air filter classification, use, characteristics

The air filter is mainly used for air intake purification to remove dust particles. In addition, the exhaust of some production processes contains small pollutants (such as radioactive substances, oil mist, etc.), although this type of purification belongs to exhaust purification, because of its high purification requirements, air filters are also required. Air filter (Air Filter) refers to the air filter device, generally used in clean workshops, clean workshops, laboratories and clean rooms, or used for electronic machinery and communication equipment such as dust. Divided into primary effect filter, medium effect filter, high efficiency filter and sub-high efficiency and other models. Various models have different standards and use efficiency.

1. primary air filter

Purpose: The primary filtration of the filter section or fresh air system in general ventilation air handling equipment.

Features: the filter material can be replaced by itself, and the initial effect of the paper frame is one-time.

2. folding medium-effect air filter

Purpose: filtration of ventilation systems. General air purification in the fields of electronics, pharmaceuticals, mechanical instruments, metallurgy, petroleum, chemical, light industry, food, etc.

Features: high efficiency, large dust capacity, small space occupation.

3. bag type medium effect air filter

Uses: 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 amount of dust.

4. activated carbon filter

Uses: Effectively remove odors, volatile agents, bacteria, viruses and various airborne pollutants, such as paint sprays, smoke, common pollutants in electronic factories and museums, and odors in food processing plants and hospitals.

Features: Highly developed microporous structure, high adsorption capacity, fast absorption and desorption, and good purification effect. The use of activated carbon filtration must have a pre-filter, otherwise, due to other pollutants in the air and reduce the efficiency of activated carbon.

5. activated carbon filter

Uses: ventilation and air conditioning systems with low air quality requirements, or places with harsh surrounding environment and high dust are used as primary pre-filtration.

Features: small resistance, easy to clean, easy to maintain.

6. sub-high efficiency air filter

Uses: all kinds of clean engineering and have special requirements of the central air conditioning and process air supply system of the end of the filter or clean room filtration.

Features: high filtration efficiency, low resistance, large dust capacity.

7. high efficiency air filter

Purpose: clean air conditioning system, high cleanliness environment.

Features: high efficiency, low resistance.

8. aluminum mesh plate type air filter

Uses: air quality requirements are not high ventilation and air conditioning systems, or the surrounding environment is harsh, dust, grease larger places as a primary pre-filter.

Features: Durable and easy to clean.

9. with fan high efficiency air filter unit

Uses: suitable for hospital sterile operating room and electronics, biology, medicine, food and other manufacturing fields.

Features: Hanging under the floor, the cleaning effect can reach 10,000 or 100,000 or 100,000, saving room space, suitable for local purification, especially in the environment where the floor is often washed in the food industry.

10. large air volume high efficiency filter

Purpose: high-performance filter for the end of the air conditioning box.

Features: high filtration efficiency, large air volume, large dust capacity.

XI. Air Supply Vent of High Efficiency Air Filter

Uses: Suitable for non-laminar flow in the form of a variety of cleanliness levels and a variety of ceiling structure of the clean room.

Features: reliable performance, easy installation and disassembly, simple maintenance.
