will only happen when temperatures begin to cool substantially
around the machine. If the air temperature surrounding the
machine is held relatively constant, condensation is not typically
a problem.
This air prep system described above will provide the CMM
with “instrument quality air” assuming facility supplied air is
reasonably clean and dry. There are cases when facility supplied
air is saturated with water or with a high concentration of oil
aerosols. This can be the result of a sub-standard compressed air
system at the facility. In cases such as this, additional filtration
and an air drier may be necessary.
To ensure a successful installation, it is recommended that the
user follow the start-up instructions in the Site Prep Manual for
customer piping. After installation, monitor system operation of
the machine to determine if the air prep package is performing
adequately. Pay particular attention to the automatic drains. The
float valves should trigger and drain contaminants before the
liquid level reaches the bottom of the filter element. Watch for
any signs of filter failure such as liquid accumulating in a
pneumatic hose or liquid deposits left on a rail by an air bearing.
If any of the situations noted above are observed, contact Brown
and Sharpe immediately.
