Non-clapboard high efficiency filter more use of glass fiber, chemical fiber class is gradually in use, some foreign manufacturers with static polytetrafluoroethylene fiber (electret) manufacturing high efficiency filter, commonly known as PTFE.
The efficient structure has and. No separator mainly adopts hot sol as the separator of filter element, which is convenient for mechanized production. In addition, it has the advantages of small size, light weight, easy installation, stable efficiency and even wind speed. Therefore, a large number of filters needed by the clean plant are mostly of non-clapboard structure. With partitions, it is highly efficient to use folded aluminum foil and paper as separator of filter element to form air passage. Partition with high quality kraft paper, hot roll forming or using offset paper as partition. The use of double-sided adhesive coated paper as a partition, the main purpose is to prevent the partition by the cold, hot, dry and wet shrinkage, so as to send out particles. When the temperature and humidity change, this kind of partition paper may have a larger particle emission, resulting in a clean plant cleanliness test is not qualified. Therefore, for places with higher requirements on cleanliness, it is recommended that customers use non-clapboard hepa filters.
The price of filter with partition abroad is higher than that without partition, so there are fewer places with partition abroad. In addition, compared with the rectangular channel with clapboard filter, the v-shaped channel without clapboard filter further improves the dust uniformity and prolongs the service life. The filter without partition for ventilation can avoid using metal parts, and is easy to be disposed of, meeting the increasingly strict environmental protection requirements. Non-clapboard filters can replace clapboard filters except for special occasions where high temperature and safety requirements are required.
