Dust Collect Round Bag 8 Ray Star Bags 12 Pleats Pleat Bag High Efficient Extend Filter Surface Bag
1. specification
Star filter bags (Star bags) is 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. Providing a wide range of star filter bags for bag house collector, which improve the performance, efficiency and bottom line of the bag house dust collector and flue.
Capacity: 300 per day (star filter bag only, ordinary dust bag excludes)
Optional fabric: PE (Polyester), PP (Polypropylene), PA (Nylon), Aramid(Nomex), Acrylic, Fiberglass, PPS, PTFE, P84, etc
Finish Treatment: Singeing, Calendering, Heat Setting, Anti-static, Water&Oil Repellent, PTFE Membrane, PTFE Impregnation and so on special treatment can be chosen
Star Bag Style: 8 and 10 and 12 pleats star bags
Bag Size: star dust bag diameters are 120mm, 130mm, 150mm, 155mm, 160mm and customized
Bag Head: seal cuff / groove snap / felt strip, bead cuff/ steel strip, etc can be chosen
Bag Body: Sewing or Hot sealing
Bag Bottom: Single or double bottom, with reinforcement or without reinforcement
2. advantage
The Star filter bags extend the filter surface, the increaing filter area compared to ordinary round ones is below,
Filter area increasing (%)

So
• longer bag service life
• increase the air volume of existing dust collectors to increase production capacity
• 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

1)Polypropylene is attacked by UV light, and will dimensionally deform under unsupported load over 82℃
2)PPS is attacked by strong oxidising agents (O2, NOx, Br2) – the presence of which, lower its recommended operating temperature
3)P84 is attacked by Sox in power station applications
4)PTFE will elongate under load at elevated temperature
