Aokai Environtec, dust filter bag making expert
Filter Bags form the heart of a BagHouse. It serves to reduce pollutants going to the atmosphere and also helps industries to recover their product. Its prudent to select the correct bags coming from a reliable company. Aokai offers bags of Polyester / Acrylic Homopolymer / PPS Ryton / Aramid Nomex / Glass Fibre /PTFE .
Meet the needs of matching filter bags to different dust collectors.
For the different types of dust collector, Aokai Envirotec helps customers to choose the filter bag reasonably and effectively, which can reduce the electricity consumption when the fan works or the compressed air required for pulse cleaning, to reduce the operating cost of the customer. The more effective the dust cleaning pressure of the dust collector, the tighter and heavier the filter bag should be used.
The requirements of different cleaning methods of the dust collector on the weight and air permeability of the filter bag:
| Dust Separation Procedure | Weight（g/㎡） | Air Permeability L/dm².min@200Pa |
| Shaking-and Reverse Air | 250-450 | 250-400 |
| Low Pressure Cleaning | 400-500 | 150-350 |
| Pulse Jet | 500-650 | 40-150 |
Filter bag, we produce excellence
Aokai Envirotec filter bags are always made according to the requirements of your dedusting equipment. It ensures the close fit of the filter bag and the tube sheet to prevent the dust from leaking from the tube sheet hole. Our filter bags are made from high quality filter cloth. Production procedure strictly complies with GB/T6719-2009 standards. We spend every effort to ensure 100% ex-factory passing rate.
