Normal Specification & Model of Filter Bags

Filter Bag Model generally is from head plate hole size with diameter between Φ120～160mm,and length 1～7m. Non-standard models can be manufactured according to clients’ requirements.

Details of filter bag dimensions such as 120mm,130mm,133mm,155mm,180mm,200mm,250mm,292mm,300mm, and that length 

1000mm,1500mm,2000mm,2400mm,2500mm,2480mm,2800mm,3000mm,3200mm,3600mm,4000mm,4400mm,5000mm,6000mm,8000mm.

Models of filter bag in use frequent is 133*1000mm,Φ133*1500mm,Φ133*2000mm,Φ133*2500mm, in which the 133*2000 is used more frequently.

Varied factors should be considered to specify bag models:bag length,air volume under process,filtering speed. Even same diameter,prolonging length to reduce bag quantities,floor space, and spares like solenoid valves,impulsive valves,blast pipes etc should be also considered.  Investment and dust collecting period can be reduced accordingly.

Round,flat and special-shaped filter bags are main forms.

a. Round shape:Tubular type filter bag whose model is indicated by Diameter x Length,that is DXL(mm)
b.Flat shape:flat shaped filter bags,including rectangle and trapezoid shapes whose model by perimeter x length:PxL(mm)

c.Special model,special shape,indicated by related dimensions.

Two filtering ways:inside filtering and outer filtering:

a.inside filter bags: dust blocked inside filter bag after be filtered through internal;

b.Outer filter bags: dust blocked outer filter bag surfaces after dusty air filtered through its outer surface.
