1.Large ventilation quantity 2.Small resistance 3.Good efficiency of the dust arrestance 4.High strength fiberglass

The whole of the autoroll is the metal structure , which is firm enough to adjustt to the worst environment. The intelligent filter material changing system may satisfy the request of the most complex system of the air current. The autoroll filter saves the energy effectively; reduces the manpower, makes the movement to work economically and stably

Using

Pre-filtrate for the air-condition and the ventilation system;

Large Dust holding capacity, the working conditions needs change frequently ;

The system of the constant air flow.

      It is made from the organic synthesis fibre. There is a  strong woven mesh which is not easy to distort at the back of the filter cotton

       The  strong elastic fibre structure, will make the filter material not to compress in together because of the wind resistance, and this structure also will not affect the dust holding capacity;

      There is agglutinant on the filter cotton in order to strengthen the power to catch the ash;

      Flame retardancy, heat resistance 120, long working life of the filter contton; it does not need to replace filter cotton frequently and will reduce the replacement cost

     Applied to the filter which change the filtration metaril automatically. It is suitable for all the other manufacturers equipment.
