Aokai Environtec, dust filter bag making expert

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

Intermittent Shaking

300-350

400-600

Shaking-and Reverse Air

350-450

250-400

Low Pressure Cleaning

400-500

150-350

Pulse Jet

500-650

40-150

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.
