  PPCA/S Air case pulse bag filter is a kind of high efficiency bag filter introduced advanced technology from America Fuller Company. It has the advantage of divided chamber and spray pulse dust filter, which overcomes the shortcoming of not enough strength and of that dust removing spray pulse and filtering at the same time. So it enlarges the application range of dust filter. The structure has special character and improves dust efficiency and delays the application life of filtering bags.It is widely used in the crushing, packing of cement factory and in dust filtering system of top silo, clinker cooler and all kinds of mills. If it is used in dust filtering of coal mill, anti-fire and anti-explosive measures should be added. The structure of filter will be changed, too. It can be used in high density dust. For example, coal mill system of O-SEPA powder separator, air dust density can arrive at over ***0g/ m3 (standard). Apply this kind of dust filter, cyclone dust filter can’t be used as I grade dust filtering except that it is used in cement industry, also in metallurgy, chemical industry, machinery and civil boiler. The material of dust filter is used terylene needle felt. The allowable temperature is less than **0℃.If aramid fiber needle felt is used for the filtering bags, the allowable temperature can reach **0℃. If temperature is higher than the allowable temperature of the above selected filtering material, measures should be taken to low down the temperature.

PPCA/S series of dust filter is outdoor type. Different chambers and different bags of every chamber compose different specifications. Bag quantity of every chamber has four types of *2, *4, *6 and **8. There are *3 specifications in total of this series. The diameter of the filtering bags is **0mm. There are two kinds of length of the bags, ***0mm and ***0mm. The whole series of dust filter can be operated in sub-pressure and positive pressure. The body structure has no changes. Dust efficiency can reach over *9.9%. Dust density after purifying is less than **0mg/m3 (standard). The main technical parameter of this filter refers to the appendix table. If this series of dust filter is used in cold areas and when the outdoor heating temperature is lower than **5℃, heating device should be added and the shell of dust filter need to add thermal insulating layer.
