Hi-Aire Tornado Selection
Air duct cleaners are always looking for better ways to get more ‘reach’ into duct systems to clean quicker, better and more profitably.
One of the most popular tools is the Hi-Aire Tornado compressed air duct cleaning range. This equipment uses a relatively high volume of air about 5.5 m3/sec (about 200 cfm) at 7 bar (100 psi). The really simple, but really useful ‘trick’ is that at this air volume, the nozzle ‘sticks’ to the duct surface. This happens because of a local induction effect. It is quite different from the ‘skipper ball’ which is familiar in the USA. The American ‘skipper’ type system works through random agitation to dislodge dust from the duct surface.
With the Hi-Aire Tornado system, you have complete controllability – it’s like being able to open up the ductwork and clean it with a compressed air gun. The nozzle can be made to negotiate turns, bends and obstructions such as damper vanes.
In takes some skill and experience, but a handy operator can do ‘Indian rope’ tricks and make the nozzle creep up a room wall and stop where you want it to – all while blasting dust at 7 bar/100psi!
It is completely counter-intuitive, and that’s why Triventek offer a video clip here http://www.triventek-
