auxillary 12 volt air compressor
I’m looking into picking up a new 12 volt air compressor that is used up front for the toilet and the floor slide. What air compressor are you using? Right now I have a Thomas model 405ADC38/12. Grainger wants nearly $500 for one. The one review was from someone that bought one and it lasted only 13 months. So was wondering what others have put in place?
thanks

This is just a general comment. Our compressors regardless of voltage have a range of devices they provide air to. When selecting a compressor the first thing I would be concerned with is if it is sufficient for the job. All compressors have a duty cycle or an amount of time they can run. For example a 25% duty cycle means out of every hour the compressor should only be required to run a total of 15 minutes.
In our coaches which are all different depending on the conversion, some aux compressors are used for everything from keeping the coach level to pocket doors to floor slide, to dump valves, to the driver seat, to slide seals, etc. Add to that the size of the aux air tank, and the condition of the system as relates to leaks, and that coach may require a very high output, large volume compressor. The flip side of that is a compressor that is single purpose, such as for awnings, and therefore can be of limited size and duty cycle because of minimal use.
I think to arrive at the best compressor for the application it is necessary to determine how much work it must do and how often it is expected to run. If the system it supplies air to has a small air tank and is leak free, with only a couple of devices a relatively small output compressor with a short duty cycle may work very well. But if the compressor is supplying air for a full time leveling system and not only has to deliver a lot of air, but at a 120 PSI pressure then the largest compressor with the longest duty cycle might be best. To add to the decision if it were me I would also consider the extent of inconvenience if it were to fail. If the compressor was both cheap and easily accessible and took 5 minutes to change I might consider the use of a $50 Harbor Freight quality compressor that I throw away every year, instead of a $500 high quality compressor that might last 5 years.

A lot of folks are now using the California Air Tools oilless compressor. They are less than $200 depending on what site you buy it from. I usually use the 3/4 hp version.

Also used California Tools compressor to replace dead Thomas one. Actually quieter than original.

I replaced my compressor with a California air unit. Very little problem to adapt the bracket. Very quiet and less than $2000

What model are you guys using?
-
I have the model 3010

Was this a 110 volt or a 12 volt unit? On the California Tools website, I have not been able to find anything 12 volt.
-
The aux compressor is 110
-
Google usually has a California Air Tools compressor ONLY unit listed for sale.
