Update on my I need air post
Recently, I posted at tiring length about my aux air compressor issue. Meantime, I have had the new compressor installed and running for well over a week. However, I really wanted to know, how frequently and for how long the compressor would come on. Unless, you hang around all day and wait for the compressor to start and stop, you will be at a loss because of the time when you are not there, not listening, whatever.
I figured that there must be a means by which all this can be measured. But I did not know what to look for. After some googling, I learned that I wanted an AC DATA LOGGER and I found the HOBO MOTOR ON/MOTOR OFF logger. By Onset Company in MA. ( http://www.onsetcomp.com )
It required a download of their software as well as the calibration of the logger unit. This took only a few minutes and was easy. The logger is very small. About 3 x 2 x 1/2 inches.
Now then, I have had the logger installed for 3 days. It attaches with a magnetic base (or Velcro or a strap) to the compressor motor case, frame or anything metal and it senses when the motor coil is being energized (switched on) and when the motor stops runnning. The logger keeps a tab of the date and the from to time runtime. I downloaded the data into an Excel spreadsheet.
Thus, I did learn that the aux compressor turns on about every 2:32 to 3:05 hours and that it runs from about 3:11 to 3:22 minutes each time.
The Hobo Motor On/Motor Off Logger cost me $97.00 on Amazon.
Expensive learning lesson but I just had to know.
Cheers,
Ronald

That’s great, I often wondered how to monitor something like you just did without waiting for it to happen and hoping you can catch the time. Good post Ronald..

Ronald, with an advertised 3000 hr life expectancy that is really good info to work out, glad the Calif Air worked out for you. Bill

Hi Bill, the compressor is very quiet and if it were not for some vibration being picked-up in the cabinet behind the front bumper, I would probably not hear it at all. I have ordered a rubber mat to place under the compressor and believe that this will absorb all of the vibration. At that point, this compressor will be as quiet as the Jun Air.
The nice thing about the California compressor is that it is air cooled / oil-less. Will see you at Parliament, no doubt.
Cheers,
Ronald

I agree on the California Air Compressors. They are priced right and fairly quiet. The best part over a JunAire is it is oiless. No SJ27 oil to eat every rubber part in the system if it gets past the drier.
So, based on your math it runs about a half hour a day. 3000 hour life…. That is about 6000 days… Better start saving for its replacement. LOL

What has a 3000 hour life expectancy ? Geo.

George, thats the advertised life for the compressor of course you time and use will vary (pc enough) and Ronald did Jim remember to tell you to remove the two black plastic head covers on the cylinders thats where a lot of the vibration comes from if you haven’t try it 4 little screws.
