An air filter is a device that collects dust and purifies gas from gas-solid two-phase flow through the action of porous filtering materials. It purifies the air with low dust content and sends it indoors, ensuring the process requirements of the clean room and the air cleanliness of general air-conditioned rooms.

The benefits of regularly replacing air filters

The efficiency of a high-efficiency filter is mainly determined based on the requirements of cleanliness; Choose the protective filter for the final stage filter, and if necessary, the filter that provides protection in the pre filter of the intermediate stage filter is called the pre filter; Selecting pre filters and their usage environment, spare parts consumption, operating energy consumption (currently, domestic users are concerned about recent energy consumption), maintenance and supply, etc. After comprehensive consideration; Special topic of concern: The high-efficiency air filter at the end of the clean room requires protection from a filter with an efficiency not lower than F8 (mainly used for fresh air treatment), and the air conditioning system also requires protection from an air filter; The key points to determine the filter: the performance of the final filter should be reliable, the efficiency specifications of the pre filter should be reasonable, and maintenance should be convenient. Based on experience, typical configurations in various places include the efficiency of local main filters, common filters, especially for ordinary central air conditioning.

The benefits of regularly replacing air filters:

1. The filter box of each exhaust fan needs to be opened every six months to check for any damage to the outer frames of the medium efficiency and high-efficiency filters, and to clean and scrub the medium efficiency and box bodies. The cleaning standards of Zhongxiao Net have strict regulations.

During this period, all types of equipment should be replaced according to the extent of damage, with a maximum service life of 2 years.

If an efficient filter is installed, open the chassis and check it every six months. Check the initial mesh frame and visually inspect whether the high-efficiency filter is damaged, aged, and effective.

When replacing the high-efficiency filter element, pay attention to the saturation level of the high-efficiency dust. When replacing, it is required to strictly follow the specifications of the production workshop, and the maximum service life of the high-efficiency filter should not exceed 5 years.

5. Each replacement is effective, and the chassis should be cleaned and observed regularly. Specific work records should be filled out in a timely manner and archived for future reference.

6. Attention should also be paid to the storage method of backup replacement medium and primary air filters. They should be packed in plastic bags and sealed, and placed in a particularly dry place. They should not be stacked or mixed with other items to prevent deformation and other issues. The model parameters of the coarse filter (concave convex filter), primary filter, medium filter, and high-efficiency filter at the inlet of each unit shall be based on the record table.

 The above is an introduction to the relevant knowledge points of air filters.
