Our unique meltblown technology allows us to produce a wide range of filtration media with fine fibers and multilayer microfibers, making it the decisive choice for filtered and fine filtered air filters in production. Its texture makes it an excellent material for ultrasonic welding and pleating processing. Act as the main filter element of pre-filter and bag filter, it can be used for intermediate filtration of air conditioning system to protect the next level filter in the system and the system itself. In places where the requirements for air purification and cleanliness are not strict, the air treated by the medium effect filter can be directly sent to the user. Using high quality two-component melt-blowing as filter material, it has large effective filtering area, large dust holding capacity, small resistance and large ventilation volume and widely used in electronics, pharmaceutical, medical, food and other industries of filtration systems. According to the efficiency specifications can be divided into efficiency specifications G4(35%), F5-F9(EN779),ePM1-2.5(ISO16890）
