It is a kind of new type of filter material. It is adopting the advantages of fiber glass and PTFE multi holes film. It can almost block powder in airflow with dust. It can keep the airflow in flux peak. It is the best material for air filing, the characters as follow: 

1.  surface filtration

2.   high efficiency in filing, and discharging up to 20mg/Nm3

3.   good venting, 30% more than other materials  

4.   little obstruction, usually below 100mm water column

5. saving money and energy

6. Long living

designed by ourselves, fiber glass has different parameter according to the fiber glass basic material. Its physical function us based on fiber glass basic material. While its filing function is on PTFE coating material. Now we would like to take EWF-600 as a n example.:
