Systems that contain comtaminants may require more frequent

compressor oil lter(s) replacement, as compressor oil lter differential should not

exceed 10 psid.

 Periodic vibration spectra should be recorded giving velocity, acceleration, and spike

energy or acceleration enveloping data against frequency every 6 months, or more

frequently if levels are increasing.

If an FFT Spectrum Analyzer is not available, vibration trending, using an overall

vibration meter may be substituted. The overall vibration meter should be available to

read Velocity (zero-peak, in/sec), and Acceleration (g’s). The overall vibration meter

Velocity range should be 0 - 1000 Hz. The Acceleration range should be 0 - 10,000 Hz.

If vibration trending is to be used to monitor changes in the condition of the

compressor, a baseline must be established within the rst 750 hours of operation and

rechecked every 3-6 months thereafter.

Overall vibration readings should be taken using Acceleration and Velocity for CMIA,

CFIA, CIV, and COV. The overall readings should be recorded and kept on le.

Action should be taken if overall vibration reading increases to 1.5 times baseline velocity

readings, or to 2.0 times baseline acceleration readings, taken at 100% Slide Valve position.

Use of Frick PhD on-board vibration analysis is an acceptable substitute for periodic

readings.
