Reducing Excessive Pressure Drop in Distribution Piping

Pressure drop in the distribution piping can be reduced by:

  • reducing the distance air travels – making the distribution system as short as possible;
  • choosing the right diamater profile in main lines and branches – smaller diameters cause higher pressure drop;
  • avoiding excessive bendes and junctions in the system, and;
  • by properly sealing connections and joints.

As changes to an the distribution system may be costly and difficult, it is important to design distribution systems with minimal pressure drop during system set-up.
