特性： 采用热融工艺，结构稳定，降低破漏风险，采用长效静电无纺布，内衬小口袋，既分流，均流，又保持袋形，降低损耗，充分利用滤料; 无旧式玻纤断裂的危险及对人体造成的不适，无导致微生物滋生的条件，而且有较长的使用寿命，***高使用温度可达80℃

Purpose: dust filter in air conditioning ventilation program

Speciality: utilize ultrasonic thermo-melt techniques; have firm structure but depressed cracking, adopt high-quality electrostatic nonwovens with pockets, diffluent equality, keep pockety. Reduce consumption and make full use of filter materials, without the danger of old fiber glass rupturing and the discomfort to human, as well as the condition of breeding microbe, long working life, the max temperature is 80℃
