Polyester needled felt have advantages of high voidage,good air permeability,high dust collecting efficiency,long service life,etc.And also have the advantage of the moderate temperature rating,the instantaneous temperature is 150℃,acid and alkali resistance is moderate,and has very good abrasion resistance.
Polyester filter bag can be widely used in all kinds of dust collecting under normal temperature.
