Portable pneumatic Jet Fans
PORTABLE PNEUMATIC JET FANS
A jet fan is a low compression range( difference between discharge and intake pressure) ejector, with a high entrainment factor (ratio between intake flow of air volume and used compressed air). Because of that, it is fit for moving large gas flow volumes by means of a little amount of compressed air, (or steam), provided the circuit resistance is not too high.(Water head does not have to run beyond 50mm).
Jet blowers , all belonging to this line of devices, operate under the same principles pneumatic jet fans do. They are virtually air flow amplifiers in as much as they are able to suck in or blow out large volumes with small inputs of the base motive air. Though sometimes used for ventilation tasks because of their mobility and small size, they are particularly convenient when some focussed punctual air draft action is needed, and can also work as water or any other liquid sprayer.
