Reply To: How to blast air…

This is not a good idea, running a blast at passers by directly from a compressor, as you cannot direct air pressure directly at a person without regulation to below 2 Bar. But the easiest way for you to accomplish what you are looking for would be to use a proximity sensor, or even better a trip valve under the floor, then releasing a shot of air form a resevoir through a large flow valve and air nozzle.
