Specification
Star filter bags (Star bags) is named pleat bag or extend filter surface bag, a special design to extend the filter surface. The Star bags are designed and developed to be integrated into existing system and process without requiring costly and major equipment changes. It is also for new bag house with high level and strict emission requirement.The pleats are gathered at the top snap band so the StarBag can fit in the same cell plate hole as a standard bag of the same diameter thereby meaningfully reducing the air to cloth ratio.
Pleated/star bag filter provides up to 2.1 times the filtration
The area of existing equipment is due to innovation
Folded/pleated design.
Increasing the filter area causes air to enter the medium
When the airflow is maintained at the same, the pressure drop is also reduced.
