Blowing Heads

The standard fibre unit blowing head is smaller than one might imagine, just 120mm long.
Here is a blowing head (lower unit) fed by air hose from its dispenser (top left).

It can be used almost anywhere. It connects to the microduct to be blown, feeding in both fibre and air.

Fibre is fed in under control by the tiny feed rollers on the left. The speed is set from a portable control box. The same rollers measure the installed fibre length.

Fibre enters the air chamber and then the microduct route.

The blowing head can be opened to permit the fibre to be removed. This does not have to be at the free end of the fibre; the blowing head can be removed at any point along a fibre.

The blowing device is automatic. If a restriction is encountered, the drive slows accordingly, applying no stress to the fibre.

With a suitable porous end cap in place, the fibre will stop automatically when it reaches the far end.

Blowing Larger Fibre bundles

There is a range of blowing heads for large fibre bundles or mini-cables.

EM25 for microcables 0.7mm to 3mm PR140 for minicables 3mm to 8mm

Breeze for minicables 2.5mm to 8mm
