120mm Diamter PE Star Filter Bag Polyester Pleat Dust Collect Bag Filter Area Increasing Star Bag
Information
For many years, the bag filter has been the main filter mechanism of the dust collector,more and more of these are being replaced by new technologies such as pleated/star-shaped filter bags.
Folded/star filter bags usually have some advantages over traditional filter bags. The pleats greatly increase the surface area of the filter, thereby reducing the air-to-cloth ratio in the same space. The pleated/star-shaped bag made of needle-punched felt can achieve a higher dust retention rate. In addition, due to the short length of the entire bag, the pleated/star-shaped filter bag remains above the intake air flow, thereby reducing wear caused by ingress of dust particles. The pleated/star-shaped filter bag is designed to replace the traditional circular filter bag used in many dust collectors.

• increase the air volume of existing dust collectors to increase production capacitySo
• longer bag service life
• lower emission
• reduce energy consuption
• reduce operation cost
• reduce pressure drop
• lower pulse jet pressure and frequence
• small bag house and building area
• lower the filter velocity
