Hi
I recall being told that if you are using a vent hose to take the air out side and to quieten the machine down, then this hose must be a larger bore than the normal extraction hose. The reason was to prevent the vacs from heating up with the back pressure created by restricting the air outflow.
Bearing this in mind, I have a question that hopefully some one may help me to get my head around.
I won't mention any particular machine or manufacturer, but I was inspecting the inside of my machine the other day and noticed that the connection hosing coming from the vac exhaust was connected within the internal bore of the vac connector stem.
Now it seems strange to me that this would be connected up in this way, as it is clearly and unneccessarily narrowing the venting exhaust pipe. Is there a logical reason why this would be connected in such a way, after being told the importance of not restricting the venting of the machine?
Over to some one who knows a little more about vac configurations and airflow etc.
But I think that I will be changing mine over soon if I don't hear any argument in favour of the manufacturers installation setup.
