The air filter has the following characteristics:
1. Purification function
The air filter can trap the dust in the gas-solid two-phase flow through the porous filter material, so that the gas can be purified, so as to ensure the cleanliness of the air into the room.
2. Type of structure of air filtration
The structure of the air filter usually includes a coarse filter and a main filter element. The role of the coarse filter is to use the high-speed rotating motion generated by the intake air to filter the larger particles in the air initially.
3. Diversified filtering methods of air filtration
The air filter can be divided into inertia type, filter type and oil bath type. The inertial filter uses the centrifugal inertia force generated when the impurity is different from the air density in rotation or sharp turns to separate the impurity.
4. Filter material type
Commonly used filter materials are oil-bath cotton, dry paper, polyurethane filter element and so on. Different types of filter materials are suitable for different filtration needs and environmental conditions.
5. Applicability of air filtration
Air filters are widely used in industrial, medical, automotive and other fields to ensure that the air quality of the operating environment meets specific standards or requirements.
6. Easy maintenance of air filtration
Most air filters are designed to be easy to replace and maintain in order to maintain their filtration efficiency and extend their service life.
7. Environmental improvement of air filtration
Through the use of air filters, indoor air pollutants can be reduced and air quality improved, which is of great significance for protecting human health and improving the quality of life.
