JetVent Fans operate on well proven longitudinal tunnel ventilation principles.The fans produce a high velocity jetof air, in turn moving a larger quantityof air surrounding the fan through a process known as entrainment. The amount of air entrained by a single fan increases with the velocity and the quantity of air being discharged by the fan.

In many industries, there are ventilation systems equipped with large scale industrial fans of high power up to or even higher than 3 MW. These are both axial and radial, which in most cases play a key role in the production process like in underground mines ventilation systems or power blocks of power plants.

The other end of the inner tube is open at the end to measure the total pressure of an airstream. The other end of the outer tube is closed to measure the static pressure through an array of pinholes. It is a device used to measure total pressure PT, static pressure PS and velocity pressure PV in ventilation ducts or fans.
