Turbine Driven Air Compressor L.O. Filter Pressure Drop Issue

Isolate your problem. One by one.

1. First check integrity of measuring transducers. Please verify "are you getting reliable reading?" What type of transducers instrument you are using
2. Check connections.
3. Have you replaced it with the same part or type of filter

The rest is just commons sense and critical thinking.

Thank you so much : gutmonarch for your suggestion, have checked our Pressure transmitter DPI 3_1 (Make: Rosemount), saying everything is oK. let us check more on integrity..

A filter's job is to block.

As a filter becomes "more blocked", for want of a better description, with time the pressure drop across it will rise with time.

Simples! ζ

You could try oil analysis to answer the following:

- Did someone put in a thicker oil?

-Did someone mix incompatible oils making a gelatinous goo?

-Is varnish clogging your filters?

or:

Are the filters the same micron size?

Verified pressure drop with another gauge?

Could the downstream flow of oil been increased, meaning the back pressure is lower, making it difficult to maintain flow and pressure through the filter?

Thank you so much Dear Mr. jhowdy..yes we are using same Micron size filters elements. we have put same grade oil but different Lubricant Manufacturer, I understand different Lubricant mfg. may use different additive chemistries..
