1. We have ability for self-developed moulds and complete mechanical processing equipments. 2. According to customer's actual situation, we design and produce filter cartridges suitable for their working conditions. 3. We independently develop filter medias with precision level from F6 to H13 (EN779 standard in Europe). 4. We have the widest pleating machine. (2. 1meters). 5. All glues are dispensed by ourselves with thermal consolidation, which makes our chemical glues are more adhesive to the media. 6. We have introduced the advanced internal rotating glue equipment, which makes gaps between the pleats of the filter media more even. 7. Our new high-temperature resistant filter cartridges have heat-resistance up to 200 degree centigrade. 8. We have introduced the advanced equipments which allow us to produce Nano-fiber filter media in bulk.9. We have stamping equipment, bending equipment, laser cutting equipment, powder spraying equipment, pleated bonding equipment and so on.
