The main advantages and features:

  1. To increase system filtration capacity by 50-150% as needed without major changes to the dust collectors ;
  2. System cleaning efficiency markedly increased with the effective increase of bag to bag distance;
  3. Bag life extended due to significant reduction of fatigue damage to the bags due to bag to cage impact.
