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?
According to the high-efficiency filter national standard GB13554-92 and GB13554-2008 to formulate quality standards: [Packaging] The outer packaging is intact, no hit, cracking traces; internal packaging (plastic bag) should be intact, foam angle, foam board Complete, model, air volume, airflow flow direction should be complete, accurate, complete, and product certificate is available. [Framework] High-efficiency filter frame surface has no obvious pollution, no unevenness, scar, no scratch, coating, no flakes, no burr, rust, high-efficiency filter frame (on one side of the viscosity) should be flat, no significant deviation; The high-efficiency filter frame strength should meet the requirements, such as placing the surface, shake, the frame has no deformation, and the shake occurs. [Seam] The seal between the high-efficiency filter paper and the frame should be strict, no gaps and holes; the sealing strip between the high-efficiency filter and the frame, should be connected, unfained, visual flat, high efficiency filters and boxes
Some customers are more concerned about whether acid-alkaline gases volatilized during the laboratory operation, affecting the high-efficiency filter in the clean room. And for PTFE filter paper and glass fiber filter paper, I don't know how to choose. In response to the above problems, Shandong Xinli has compared the PTFE filter paper and glass fiber filter paper: Shandong Xinli PTFE high-efficiency / super efficient filter, high-quality PTFE filter material, has a reliable filter level of H13-U16 level, and low wind resistance, Small energy consumption, can be widely used in semiconductor, electronics, precision manufacturing, biopharmaceutical and other industries. The company has advanced production and monitoring equipment, with advanced HEPA & ULPA filter leak detection platform, perfect testing procedures, strict quality assurance system and management system, and the high-efficiency / super efficient filter of Shandong Xinli factory is strictly followed. EN1822: 2009 standard for changing point-by-point automatic scanning
The junior high-efficiency air filter refers to air filtration units, generally used in clean workshops, cleansing plants, laboratory and clean rooms, or for electronic mechanical communication equipment. There is an initial filter, a medium-role filter, an efficient filter and a sub-efficacy model. Various models have different standards and performance. ◆ Reasonably determine the efficiency of the filter at all levels, the last level filter determines the degree of air purification, and the upstream level filter mainly protects the lower wind filter to extend its service life, or protect the air conditioning system. To ensure its normal work. In the air conditioning design, you should first determine the efficiency of the last level filter according to the user's cleanup requirements, then select the protective filter, if this level filter needs to be protected, it is necessary to add a filter in its upper wind. Protect the filter collective \"pre-filter \". The efficiency of each of the filters should be properly matched. If adjacent two levels
(1) Confirmation and verification of pharmaceutical production companies 1. A series of activities for drug production enterprises: It is a series of activities that certify plant, facilities and equipment correctly and achieve expected results. 2. Verification of pharmaceutical production: It is a series of activities that prove any operating procedures (methods), production processes or systems. (2) Confirmation of the clean room of the drug factory can be divided into: 1. Design confirmation: design confirmation is to prove that the design of plant, facilities and equipment meets the requirements of the predetermined use and \"drug production quality management specification \". 2. Installation and confirmation: Installation of the master is to prove the construction and installation of plant, facilities and equipment, meet the design standards to meet the requirements of the production process. 3. Run confirmation: Run confirmation is to prove the stability, reliable operation of the plant, facilities and equipment and meet the design standard. 4, performance confirmation: Performance confirmation is to prove that the plant, facilities and equipment can continue under normal operation methods and normal process conditions
