Monitoring Your Air Compressor.

I was reading a post in the "Air Tanks, Pumps & Compressors" thread and a comment was made about having an hour-meter installed on your compressor.
In my 20+ years in the Navy I stood many watches on operating equipment in the engineering spaces of a nuclear powered submarine and the importance of monitoring that equipment cannot be over emphasized. That monitoring along with planned controlled maintenance will generally prevent unexpected and sometimes damaging breakdowns. Part of that monitoring involved taking and logging readings of thermometers, pressure gauges and other installed instrumentation hourly. When I retired from the Navy, I figured that part of my "adventure" was behind me but it is surprising how some things will always stick with you. 
I'm sure that most of us probably pay close attention to maintenance on our cars and trucks but other equipment we might not. My previous Navy "training" probably made me more conscious of "equipment" I own. I was reminded of this when "humdinger" mentioned that HP air compressors should come with an hour-meter installed. I fully agree.
When I purchased my Shoebox 8 earlier this year, the first thing I installed was an hour-meter. The maintenance items on the Shoebox and any troubleshooting required seemed to fit time related monitoring. 
I made up a log sheet to track the different parameters of my air charging station (my past Navy experience kicked in). I can look at this log and see; 1) trends that are developing, 2) Air leaks, 3) decreasing output, 4) Reminders for checking filters, desiccant, lubrication, belt, Etc.
Don't get me wrong, I don't go overboard and keep a log sheet on my vehicles, lawn mowers, or other minor equipment, but I believe that HP air compressors lend themselves to this type of monitoring and an inexpensive, easily installed hour-meter is an excellent tool to aid in this monitoring.

Bleudg, couldn't agree with you more! Having owned high end Scuba compressors in another life, it always seemed to be prudent to be thorough in the record keeping for troubleshooting and maintenance. Besides the fact when you ever decide to sell the compressor, having the records will help support the resale value! Keep up the pressure and the good work!! lol.
 
Linsfreak,
I am sure that I'm using more filters then are needed. Before I got addicted to Airguns and PCP's I used my oil-less compressor and refrigerated dryer (with the filter/regulator manifold shown) for air brush model painting. As you might know, oil and water contamination can destroy a paint job. The manifold shown has from left to right, Regulator/Filter moisture separator, Oil Coalescing filter, Final Coalescing Filter .01 micron, and Final Regulator. I added the large Wilkerson filter on the right, it is the X03-02-000 Desiccant filter.
I also have the Diablo molecular sieve filter on the Shoebox outlet. 
 
The first regulator/filter has an auto drain valve that automatically expels any water buildup. I hear it blow off once or twice during a charge. The oil-less compressor cycles about four times when charging my Tiger Shark tank from 3000 to 4400 psi (about 1.5 to 2.0 hours).
I had to "recharge" the desiccant in the Wilkerson dryer after approximately 30 hours of Shoebox operation. The Diablo is still good so eliminating/minimizing the moisture on the "inlet" side might be the key!
If I was to change anything I would probably put one of those particulate filters on the outlet side of the desiccant filter to trap any desiccant "powder" carryover.
 
Linsfreak,
When I inspected my desiccant filter, I noticed that the blue "tracer" beads in my desiccant had turned white in the area of the aluminum "standpipe". The beads on the outside edge against the plastic bowl were still blue. This channeling may be due to the low flow rates associated with this setup. I went ahead and renewed the desiccant last week and will recheck it in a couple of weeks to see if it happens again. As I mentioned in another post, my dew points here in South Carolina have been high (especially this last couple of weeks lol..;^)) I have also been getting more water from the oil-less compressor tank after each charging session. The physics shows that pressurized air systems magnify/generate moisture.
