初、中、过滤器的适用范围

                初效过滤器主要适用于空调与通风系统初级过滤、洁净室回风过滤、局部过滤装置的预过滤，主要用于过滤 5μm 及以上粒径的尘埃粒子，使用计重法测试。也用于多级过滤系统的初级保护。过滤材料有无纺布，尼龙网，铝波网，不锈钢网等，无纺布滤料出风面经过光整处理，防止无纺纤维断裂飞散造成二次污染。

                中效过滤器系列产品广泛应用于工、商业、医院、学校、大楼和其它各种工厂空调设备(系空调系统的初级过滤，以保护系统中下一级过滤器和系统本身，在对空气净化洁净度要求不严格的场所，经中效过滤器处理后的空气可直接送至用户)，也可以安装于燃气轮机入风口设备或电脑室，以延长设备使用寿命。

                 过滤器适用于常温、常湿，允许含有微量酸、碱有机溶剂的空气过滤，广泛应用于航天、航空、电子、制药、生物工程等精密领域。主要用于滤除空压机吸入空气中的粉尘杂质；防止其他异物进入主机，对主机造成损伤。

                  Efficient filter is mainly suitable for air conditioning and ventilation system at the beginning of the primary filter, clean room return air filter, local efficient filter filtration, more than 5 microns and is mainly used for filtering particle size of dust particles, test using weight system，Also used for primary protection of multistage filtration systems.The filter material has non-woven fabric, nylon mesh, aluminum wave net, stainless steel mesh, etc., the non-woven fabric filter can be used to clean the air to prevent the non-spinning fiber fracture from causing secondary pollution.

            Medium - effect filter series products are widely used in industrial, commercial, hospital, school, building and other factory air conditioning equipment（Air conditioning system of the primary filter, the middle and lower level filters in order to protect the system and the system itself, not strict on clean air cleanliness, after effectively filter in the treatment of air can be directly sent to the user），It can also be installed in the gas turbine air outlet equipment or computer room to extend the service life of the equipment.

                 High efficiency filter is suitable for air filtration, which contains trace acid and alkali organic solvents. It is widely used in precision fields such as aerospace, aviation, electronics, pharmacy and bioengineering.It is mainly used to filter the dust impurities in air by air compressor. Prevent other foreign objects from entering the host, causing damage to the host.
