What are the key factors affecting the filtering accuracy of medium - effect filters?

Medium effect filter refers to the large diameter impurity particles allowed to pass through. Filter element is the key to affect the filtering accuracy of medium - effect filter. Different filter elements can be selected according to the needs of the following components to achieve the corresponding filtering accuracy.

1, medium effect filter filter precision - filter according to indoor cleaning standards to determine the efficiency of the filter, reasonable selection of filter combination series and all levels of efficiency. If the indoor requirement is general purification, you can use the main filter; If the indoor requirement is medium purification, the primary filter and two-stage filter should be used; If the indoor requirement is super purification purification, the primary and middle effect three purification filters should be used, and the efficiency of all levels of filters should be reasonable and properly matched. If the efficiency of the two adjacent filters is too poor, the former should be used. One filter cannot protect two filters.

2. Filter precision of medium effect filter - the filter correctly determines the dust content and dust characteristics of outdoor air. Because the filter is designed to filter and purify outdoor air into the room, the amount of dust in the outdoor air is a very important data. Especially in multistage purification and filtration processes, the selection of prefilters should consider the environment, spare parts cost, operation energy consumption, maintenance and supply, etc.

3, medium effect filter filter precision - filter can be correctly determined filter characteristics. The main characteristics of filters are filtration efficiency, resistance, permeability, dust capacity, filtered air speed and processed air volume. Under permitted conditions, should choose as far as possible high efficiency, small resistance, large dust capacity, moderate filtration speed, large air handling capacity, easy to manufacture and installation, low price filter. Economic analysis of one-time and multiple performance and energy efficiency ratios is required when selecting filters.

4, medium effect filter filtering accuracy - filter, analyze the characteristics of dust gas. The main characteristics of dusty gases relevant to filter selection are temperature, humidity, amount of acids, bases and organic solvents. Because some filters are allowed to be used at high temperatures, while others can only work at room temperature and humidity, the amount of acids and bases in dusty gases and organic solvents can affect the performance and efficiency of the filter.
