Primary filter is mainly applied to air conditioning and ventilation system primary filter, clean room return air filter, high efficiency filter pre-filter device locally, mainly used to filter 5um particle size of dust particles and above. Is also used to protect the primary multi-stage filtration system, Yu was the company’s early efficiency filters have a plate, convolution, three types of bag, frame materials paper, aluminum, spray cold plate, galvanized sheet and stainless steel plate style filter non-woven material, chemical fiber, glass fiber, nylon nets, non-woven filter media outlet side after finishing treatment, to prevent the scattering of non-woven fiber breakage cause secondary pollution. Filtration efficiency of 35% ~ 95% @ 5um (weight method). Primary filter Note: can be customized according to customer requirements specific air purification system in the first stage of the filter material. Products have been successfully used in electronics, electrical appliances, aerospace, automotive, medical, telecommunications and environmental protection industries and banking, smart buildings, hotels and other clean environment within In effect filter is mainly used in central air conditioning and central air systems. It can be used for primary filtration air conditioning system to protect the system in the next level of the filter and the system itself, the cleanliness of the air purifier is not critical places, in effect through the air after filter processing can be directly sent to the user. My company’s efficiency bag filter (bagfilter) have a border spray cold plate, galvanized sheet, etc., can also be made of non-woven filter material frameless, glass fiber, filter diameter of 1 ~ 5um, filtration efficiency of 60 to 95% (colorimetric method).
