Performance comparison of filters, ultra-clean workbenches, air showers, transfer windows, and air intake purification equipment 01

The air filter is mainly used to purify the intake air and remove the dust particles in it. In addition, the exhaust of certain production processes contains fine 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.

Intake air purification is characterized by low dust concentration and fine dust particles in the processed air, and high purification efficiency is required. According to the different purification efficiency, the classification and performance of the air filter.
Note: Air dust counting method is used for general filters, and DOP method is used for high-efficiency filters.
can also be divided according to the specific use, characteristics and structure of the air filter, such as:

(1) Primary air filter
Purpose: The filter section of general ventilation air treatment equipment or the primary filtration of fresh air system.
Features: The filter material can be replaced by itself, and the initial effect of the paper frame is one-time.

(2) foldable medium-efficiency air filter
Use: filtration of ventilation system. General air purification in the fields of electronics, pharmacy, mechanical instrumentation, metallurgy, petroleum, chemical industry, light industry, food and so on.
Features: high efficiency, large dust holding capacity, and small space occupation.

(3) Bag type medium-efficiency air filter
Usage: Central air-conditioning centralized ventilation system, or as the pre-filter of the high-efficiency filter, it can reduce the burden of the high-efficiency filter, extend its service life, and can also be used for general air purification in the industrial field.
Features: small resistance and large dust holding capacity.

(4) Activated carbon filter
Purpose: Effectively remove odors, volatile agents, bacteria, viruses and various air pollutants, such as paint spray, smoke, common pollutants in electronics factories and museums, and odors in food processing plants and hospitals.
Features: highly developed microporous structure, high adsorption capacity, fast absorption and desorption speed, and good purification effect. The use of activated carbon filter must have a pre-filter, otherwise, the efficiency of activated carbon will be reduced due to other pollutants in the air.

(5) Nylon mesh air filter
Usage: Ventilation and air-conditioning systems with low air quality requirements, or places with harsh surroundings and high dust are used as primary pre-filters.
Features: low resistance, easy to clean and easy to maintain.

(6) Sub-high efficiency air filter
Usage: All kinds of clean engineering and end filtration of central air-conditioning and technological air supply system with special requirements or filtration of clean room.
Features: high filtration efficiency, low resistance, large dust holding capacity.

(7) High efficiency air filter
Purpose: Clean air conditioning system, high cleanliness environment.
Features: High efficiency and low resistance.

(8) Large air volume high efficiency filter
Purpose: High-performance filter at the end of the air-conditioning box.
Features: high filtration efficiency, large air volume, large dust holding capacity.

(9) Aluminum mesh plate type air filter
Use: Ventilation and air-conditioning systems with low air quality requirements, or places with harsh surroundings, dust, and grease as primary pre-filtration.
Features: Durable and easy to clean.

(10) High efficiency air filter air outlet
Usage: Suitable for non-laminar clean rooms with various cleanliness levels and various ceiling structures.
Features: reliable performance, convenient installation and disassembly, and simple maintenance.

(11) High efficiency air filter unit with fan
Usage: Suitable for hospital aseptic 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, saving room space, suitable for partial purification, especially in the environment where the floor is often washed in the food industry.

(12) Air shower room
Usage and characteristics: The air shower is a personal purification device used by operators when they enter the clean room. It uses high-speed clean air to blow off the dirt on the people entering the room. The nozzle can be adjusted to effectively remove dust on the human body and prevent external pollution from entering the clean area. It can also be applied to the blowing of bulky goods.

(13) pass window
Usage and characteristics: A device to transfer items in the clean area to reduce the number of door openings, which reduces the pollution of the clean room. It is mainly used for the transfer of small items between clean areas of different levels, and between clean areas and non-clean areas.
