Comparison of 3 types of bag filters:
 
Types Advantages Disadvantages
Shaker High collection efficiency Low air-to-cloth ratio (1.5 to 2 ft/min)
Strong woven bags Restricted to low temperatures
Easy operation Larger space required
  Larger number of filter bags required
  Frequent maintenance
  Operators must enter bag filter to replace bags which creates potential for toxic dust exposure
  Poor cleaning efficiency if positive pressure present
Reverse air High collection efficiency Low air-to-cloth ratio (1 to 2 ft/min)
Preferred for high temperatures Frequent maintenance
  Unable to remove residual dust buildup
  Clean (output) air must be filtered
  Operators must enter bag filter to replace bags which creates potential for toxic dust exposure
Pulse jet (Reversed Jet) High collection efficiency Dry compressed air required
High air-to-cloth ratio (6 to 10 ft/min) Restricted to low to medium temperatures
Aggressive cleaning action Unable to function with high humidity gases
Continuous  
Strong woven bags  
Lower bag wear  
Smaller space required  
Bag changing without entering bag filter
