6.1.2 Routine Component Replacement
The lifetime of certain parts is based on the number of cycles the unit has completed, or
on hours of operation. Table 6.5 lists the average number of hours or cycles one should
use in determining when components should be replaced. Ambient operating temperature
also affects lifetime. Higher temperatures reduce the number of cycles and hours before
replacement is suggested. The charts below are for equipment operating at a temperature
of 72 to 75
o
F (22 - 24
o
C).
The lifetime of system pneumatic components is influenced by the quality of the
compressed air provided. All Branson systems require clean, dry, (normal) factory
