Many HVAC systems in the hospital use 100% outdoor air, which is a good strategy for preventing patients from cross -microorganisms in HVAC systems. However, 100% outdoor air does not eliminate the growth of microorganisms in the air filtration medium and its adverse effects on the nursing environment. Therefore, many hospitals still need advanced HVAC systems. The clean room of the health system was first used in the operating room. At the beginning, it was widely used in orthopedic surgery, because the orthopedic surgery was longer and it was easy to cause infection.
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?
Asian high efficiency filterWhat are the main purposes? The following is given you a detailed introduction by Shandong snyli's Xiaobian:Asian high efficiency filters are also called sub-high efficiency air filters, which are often used for the front end of the high-efficiency filter, and better prot
The medium-efficiency filter belongs to the F series filter in the air filter. The F series of medium-efficiency air filters are divided into bag-type and non-bag-type. There are many problems that need to be paid attention to when selecting equipment. The following editor will explain what knowledge you need to refer to when choosing a medium-efficiency air filter: Effective air filter method 1: According to the requirements of the purification standard 1. If the indoor requires ultra-clean purification, a combination of primary, medium and high-efficiency three-stage purification and filtration should be used; 2. If the indoor requires medium purification, Two-stage filters of primary effect and medium efficiency should be used to cooperate with each other; 3. If the indoor requirement is general purification, the primary effect filter can be used. Method 2: Be familiar with the characteristics of the filter. The so-called characteristics mainly refer to various factors such as filtration efficiency, resistance, penetration rate, dust holding capacity, filtration wind speed, and processing air volume. High efficiency should be selected as far as possible when conditions permit
Medium efficiency filterWhat are its characteristics? snyli Purification will answer for you!The medium-efficiency filter, as the name implies, is the layer of filter sandwiched between the primary effect and the high-efficiency filter. It is used in the purification of pharmaceuticals, hospitals, e
