Special filter cotton for Nanjing Yixiou roller shutter air filter – Automatic Roll Air Filter

1Automatic rolling curtain filter cotton is made of organic synthetic fiber or glass fiber after compression and rolling., The back of the filter material has a strong woven mesh,Not easily deformed; Super elastic fiber structure,The filter materials will not be compressed together due to high wind resistance and affect the dust holding capacity.;

2the filter cotton is sprayed with a special adhesive agent,Strengthen ash catching ability;

3temperature resistant120℃, Filter cotton has long life,No need for frequent replacement, reducing costs;

Technical parameters:

Notes on replacement:

1. For life safety and equipment maintenance considerations, two people need to work together when replacing the filter material to avoid the filter material tilting during winding;

2. When pressing the door lock, you need to hold the new filter box by hand to prevent it from falling suddenly;

3. When replacing the filter material, pay attention to the winding direction. When viewed from the left, the winding is counterclockwise and downward, as shown in the previous figure;

4. Before the new filter material passes through the upper filter material adjustment round tube, the filter material must pass under the square tube compression frame, see the previous picture;

5. When replacing the filter material, pull it down slowly and at a constant speed;

6 . Regularly check the transmission part, adjust the large and small sprockets to make them on the same working plane, and feed the chain regularly.
