  • Backup Aux Compressor

    Posted by Archived on February 13, 2012 at 7:52 pm

    I’m looking for a backup aux compressor that I can plumb into the
    aux air in the steering compartment should my aux compressor fail.
    The reason is, if my compressor fails, there is no way to use the
    toilet and that is a serious problem! If it wasn’t for the toilet, I
    would just shut off the aux while using the bus.

    I could also plumb it into the fill valve in the engine
    compartment and have plenty of room to mount a spare compressor. The
    pancake compressors would work best, but I know there are lots of
    various 12 and 120 volt compressors that could be used. I would need
    to maintain 60 – 90 psi.

    Any suggestions?

    Need air for a leveling system when parked? If so, then a compressor to help run it and the toilet makes sense but if not, why not convert to a toilet that uses a 12 volt electric feed to flush which matches more closely the “camping configuration” of our coaches. Just one thought. I realize, this option is more money as I just bought a 12 volt toilet from CW that cost $450 but, it is an option.

    Absent in the question is information about the condition of the aux air system relative to leaks, and how often the current compressor has to run. You already have backup if you need it. Just start the engine. But if you really want back up you also have some options. Russell Coach uses a toilet with a macerator that eliminates the need for air, plus it is reliable and trouble free. That’s one option. Another is if you have the room add a another tank just ahead of the toilet with a check valve ahead of it. If your aux air system leaks down the check valve holds air in the tank and depending on how much air a flush requires the tank may give you several days worth of air supply.

    If you need a reserve compressor assuming you have room, I would go with a cheap 120 volt small volume air compressor such as would be used to fill car tires, bike tires or basketballs strictly for emergency use and located in a bay to protect it from the elements. The steer compartment is exposed to moisture, road salt, etc.

    Couldn’t do the CW thing, mine is rear discharge and not a direct drop. The only electric option would be to upgrade to a macerator style jet toilet that would have sufficient water pressure to move the discharge to the holding tank. Those toilets are very expensive.

    I do have room in a bay for a small compressor that I could quick couple to the existing aux compressor. That may be the best way to go, providing I can find a compressor that will fit in the limited space. I don’t want a cheap throw away compressor because if the aux goes Tango Uniform, it will take time to locate and order a new one. The steering compartment isn’t really an option due to space anyway.
