These are excellent units, by far the best we have found. The turbo blowers are
fitted onto a lightweight aluminium frame that is fitted with braked wheels.
There is a space at the back of the dolly to stand the gas bottles and the
whole unit can be wheeled around very easily with 2 x 100kg gas bottles on
board! The unit can operate from either 1 or 2 gas bottles. Two are recommended
as the pressure inside the tank lasts for twice
as long before the cylinders need to recover. The unit can operate with either
Liquid Co2 or Gas Co2.
Using liquid is more powerful, but you will see a white plume from the horn
(similar to a fire extinguisher). There is
a very small risk that the valve will freeze up if using liquid. |
