The air box and tube clamp are now set up to blow air through the tube.
1. Connect the air as for normal blowing.
2. Make sure there are personnel at the other end of the tube run, and that they are aware
that the air is to be turned on.
3. Make sure that a suitable device is fitted to obviate injury should any object be expelled
from the far end of the tube.
4. Apply air to the Breeze
The far end of the tube run should be monitored; air should be leaving the tube under reason-
able pressure. The minimum pressure required will vary with the length of tube in the run, the
friction characteristics of the tube, the cable and the lubrication being used. As a starting
point, the air leaving the far end of the tube should be (at least) similar to a light breeze. Bear
in mind that if the tube run is of considerable distance, it may take a few minutes for the air to
reach the far end of the tube.
If after waiting a suitable time there is no air leaving the far end of the tube, this would indicate
that there is a blockage or similar obstruction in the tube run, or, that the tube is fractured. In
either case the fault should be corrected before any attempt is made to blow cable through
the tube.
Once the tube integrity has been confirmed by the method outlined above. The tube may be
lubricated.
1. Open the air box and tube clamp assembly, withdraw the tube and raise it so that the lubri-
cant will pour into it easily and not overflow from the top.
2. Pour lubricant (available through GMP) of recommended quality and quantity down the
tube. Insert a suitable foam plug into the tube and put the tube back into the air box and
tube clamp.
The air box and tube clamp assembly are now set up to blow the foam plug through the tube
and deposit an even coating of lubricant to the inside walls of the tube.
1. Connect the air as for normal blowing.
2. Make sure there are personnel at the other end of the tube run, and that they are aware
that the air is to be turned on. Make sure that a suitable device is fitted to obviate injury
should any object be expelled from the far end of the tube.
3. Apply air to the Breeze
When the foam plug has been expelled from the far end of the tube run, cable can be in-
stalled into the tube.
Note: When the air is turned off, after checking the tube integrity and sending the foam plug
down the tube to spread the lubricant, it may take some time for the pressure in the tube to
fall back to low levels.
