Air filter regulators are generally divided into three categories according to purification needs, specific uses, and purification efficiency: primary filters, medium efficiency filters, and high-efficiency filters.

First, Introduction of primary filter:

The primary filter is suitable for the primary filtration of air conditioning and ventilation systems and is mainly used to filter dust particles above 5 microns. The characteristics of the primary filter are small resistance, large air volume, washable, lightweight, good versatility, firm and stable outer frame structure, etc., to ensure that the primary filter will not be deformed or damaged in a poor environment.

Second, the medium efficiency filter overview

Medium-efficiency filters are mainly used for intermediate filtration of central air-conditioning ventilation systems, which can filter 1-5um (micron) dust particles, and are widely used in pharmaceuticals, hospitals, electronics, food, optoelectronics, and other industries. The characteristics of the medium-efficiency filter: large air volume, small resistance, high dust holding capacity, simple and convenient replacement, etc., and the windward surface is large, which is considered to be an excellent medium-efficiency filter structure at present, and is used in modern industrial and civil ventilation systems. Lots of products.

Three, a high-efficiency filter

The high-efficiency filter is mainly used to capture particulate dust and various suspended solids below 0.5um and is suitable for terminal filtration of clean ventilation systems. High-efficiency filters are divided into high-efficiency filters with partitions and high-efficiency filters without partitions. The filter paper used in both is the same. The difference is that the volume of high-efficiency filters without partitions is lighter and thinner than high-efficiency filters with partitions. The air volume of a high-efficiency filter without a partition of the same volume is smaller than that of a high-efficiency filter with a partition. At present, it is recommended to use high-efficiency filters without partitions in places with high cleanliness requirements, because they have the characteristics of small size, lightweight, easy replacement, stable efficiency, and uniform wind speed.
