This is a really bizarre statement. You throw some numbers up and then say “obviously it should work how I said”. But it’s not obvious at all. Those numbers don’t intuitively tell me that it should my hands in 5 seconds. Indeed my intuition (and that manufacturer’s specs) says that’s wildly inaccurate.
I’m really confused by your “1 meter away” claim. At a meter away you’re basically just waiting for ambient air to dry your hands. The fact that they measure decibels a meter away doesn’t mean that’s where your hands should be.
- TeMPOraL 7y agoMy statement is this: I've used a sub-2kW blower that could dry hands in below 10 seconds, was loud but not painful, and if you somehow made it portable, it could double as a leaf blower in a pinch. 1 meter from the nozzle the stream was still powerful enough to dry hands faster than ambient air. So the numbers people throw around this thread are weird, they imply unrealisticly wet hands, or ridiculously inefficient dryers.
- dpark 7y agoI think the fact that your numbers are so much drastically lower than the manufacturer’s numbers indicates that your numbers are not representative of the typical experience. Maybe you can dry your hands in five seconds with the typical air dryer. It’s clearly not true for most people. Maybe you shake your hands extremely dry before going to the dryer. Maybe after using the dryer your hands are still wet and clammy. I don’t know. Your experiences are clearly not reflective of the typical case, though.
