Maintenance Procedures
The following procedures are added to supplement the information presented earlier in this
manual in Section 3, Operation, under the heading Initial Start Preparation.
Main Driver
Depending upon the customer's requirements, different drivers are used with the Centac
compressor. Consult the driver manufacturer's literature provided in this manual to insure
proper lubrication and maintenance procedures.
Control Panel
The control panel checkout procedure is designed to verify that a control panel is
functioning properly. The checkout can be used for initial testing or in conjunction with
routine maintenance schedules.
Refer to the control drawings and checkout procedure included with the Control Panel
Instructions in this manual to insure proper adjustments and calibrations.
Intake Filter
All filtration systems have a maximum recommended pressure drop at which the filter
element should be cleaned or replaced. Because of the many types of atmospheric
conditions that exist it is difficult to accurately determine the life of a given filter element. It
is therefore advisable and highly recommended that a weekly pressure drop measurement
be recorded for both the primary and final stage filter elements to determine the useful
element life.
Filter maintenance is a necessary and important part of the entire air system. A properly
maintained inlet air filter will result in optimum air compressor operation. An increase in
filter differential pressure is an indication that the inlet air filter is performing as intended.
