    SLS pump as compressor?

    I want to install a airtank from a Rangie and then use the now unused SLS air pump as a compressor.
    I've heard that it should be up to the task and that one can only cut the wiring loom and add a switch to activate the pump.
    Possible or not and if so where do one cut the wiring loom?

    Thanks
    Rudolf

    Short answer - NO

    Long answer - only 5% duty cycle, so in every 30 minutes, can only use the compressor for 1.5 minutes or so, without causing it damage. So, useless as a general use compressor. Lots of threads in AULRO on the topic, including a WABCO diagram that specifies the 5% duty cycle.

    So, another compressor with a useful duty cycle, (ie at least 50%, up to 100%) is required for a compressor.

    Thanks,
    Did a couple of searches but did not find anything.
    The common misconception is that the pump is 100% duty.
    New pump would be installed.
