Note
: If the air line is more than 50 metres log, size the line so that
the pressure drop does not exceed 0.2 bar.
Try to limit the number of connections in the air and water lines to the
minimum possible.
The use of elbow or “T” connectors and reducers/adapters will increase
the pressure drop in the lines. The diameters shown in the tables have
been selected considering the use of a pair of connectors in each line, if
the number of connectors doubles choose the next largest diameter.
