In the pharmaceutical industry, high -efficiency filters (HEPA) are used for the processing and filter of the processing and filtering of space air. Sterile production requires compulsory use of high -efficiency filters, and the production of solid and semi -solid dosage forms is sometimes used. H13 to H14 (DIN1822) is two types of high -efficiency filters, with an interception rate of 99.995%. But how long does it take to change?

1. The basic knowledge of the filter is the main purification device of the clean room, which is the main means of air purification. Therefore, it is very important for the basic knowledge of clean room design, construction, and maintenance management to understand and master the filter. A. The classification of the filter is divided according to the performance of the filter (efficiency, resistance, dust removal), usually divides it into a coarse, alive, high-efficient, sub-efficient, efficient (HEPA) and ultra efficient (ULPA) Six types of filters.

The mid-range filter is very common in the use of central air conditioning units, especially in the collective air supply system, some primary filter systems are also equipped, and the annual market demand is still much. The key to the purchasing of the mid-range filter includes many aspects, one is to see parameters, such as the high and low air volume, and the size of the dust removal.

The dust controlled and filtered by clean technology is generally 0.1--10μm dust particles with small particle size, including solid particles and liquid particles; the organic particles suspended in the atmosphere include microorganisms, plant pollen, fluff and fluff. The main control of air purifi
