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

There are many kinds of air filters, filtering features, different fields, what is the PTFE high-efficiency filter? Where is his characteristics and application fields? First PTFE is PTFE (Poly Tetra Fluoroethylene), a short written PTFE, commonly known as \"Plastic King \", is a polymer polymer prepared as monomeric polymerization. White waxy, translucent, heat resistance, excellent cold resistance, can be used for a long time of -180 ~ 260oC. Such materials have an antide-resistant alkali, and the characteristics of various organic solvents are hardly soluble in all solvents. At the same time, polytetrafluoroethylene has a high temperature resistant to high temperature resistance, which is extremely low, so it can be lubricated, and it has become an ideal coating of the inner layer of easy cleaning water pipe. The PTFE high-efficiency filter is a high efficiency air filter made of PTFE film filter. He has high efficiency, pressure

First, clean level 100, 100,000 and 100,000 air purification treatment should be used in the first, medium and high efficiency filters. For 300,000 air purification processing, sub-high efficiency filters can be used instead of high efficiency filters. Second, the selection of air filters, the arrangement method should meet the following requirements: (1) The medium-effective air filter should be set in the positive pressure segment of purifying air regulation; (2) Efficient or sub-high-efficiency air filter should be provided at the end of the purified air conditioning system (3) The efficient air filter should be selected by less than or equal to the rated air volume. Third, the area of ​​the area is large, the air clean is high, the position concentration and noise, the vibration control requires a strict clean room (region), which should be used in centralized purification air conditioning systems. Conversely, a decentralized purification air conditioning system can be employed. The air purification system of the following conditions should be set out: (1) One-way

The production and development of the laminar flow operating room With the development of medicine, the development of surgical technologies requires high-profit net surgical environment, large-scale burn surgery, craniocerebral surgery, ophthalmic surgery, lung surgery, longitudinal surgery, etc. High difficulty must be super clean In the environment, the surgical infection rate is minimized to ensure success. The laminar flow operating room has become a major revolution in the operating room for the development of the operating room, so that the success rate of surgery rose a new step. The laminar flow operating room layer flow pure operating room is a multi-purpose air cleaning measures to filter dust particles in the air, making bacterial without carrier, thereby effectively preventing and controlling infection, providing a suitable temperature, humidity environment, The patient is treated as few damage during surgery. The air purity level of the laminar flow operating room According to the Ministry of Construction, \"Hospital Clean Surgery Building Technical Specifications (GB50333-2002)\", laminar flow surgery
