<p>The air jet device has the jet outlet (a) axial to the fan (b) and the transmission (c), so the air moves axially. The transmission is integrated into the jet (d), so the whole device is a single chamber system. Air comes in through the inlet (f). The manual drive crank (e) can be folded up. The entire device is only 5 cm in diameter, so can easily be carried in a trouser pocket.</p> |
