Will a centralized system extract dust and fumes equally from all intake points?

When designed properly, a centralized system will indeed collect fumes equally well from all of its intake points. Air quality engineers are experts in these matters and take many variables into consideration. These variables include:

  • The size of each intake point and how close the intake points are to the collection unit.
  • The number of intake points. More intake points will require more horsepower from the motor.

The gates on a duct system are like valves, and they should be sized according to how close they are to the source of suction (the dust collector)—closer gates will be smaller than ones farther away. Sizing gates in this way, an engineer will balance a system so that every dust- or fume-generating application gets the amount of suction it needs.
