I don't know that that is the case. I have certainly never heard that before. But let's assume it is. For hull cleaning, there is no need to have accumulator tanks and the associated plumbing. A high-quality compressor (not some Chinese-built POS from Home Depot) will run continuously for many, many hours without the need to shut down or cool off. Further, at the depths we are talking about, the air hose will hold enough reserve air to get to the surface easily in the event the compressor shuts down for some reason.
I do not recommend using a hardware store compressor as the base for hookah system, but I know plenty of hull cleaners who do, with no ill effects AFAIK
