729 flat cylinder PET filter material

729 series of flat/cylinder PET filter material is woven with high strength PET fiber, after heating and some other treatments. Widely used in industrial dust cleaning and smog treating.

729 series of flat/cylinder PET filter material is fit for shaking bag filter. It can continually work under the temperature  130¡æ. And also,       it can work for a short time in  150¡æ.

 150¡æ. But it is not advisable to use it in fibrous and bonded dusty  environment. However, we can use filter material with  hydrophobe and lipophobic treatment for filter damp and smeary smoke dust.; If the smoke dust with explosive medium, we can choose the 729 £­ E after static-resisting treatment.
