Cable Blowing Machines – Your Questions, Answered

When it comes to installing fiber optic cables, choosing the right method can make all the difference. Below, we’ve answered the most common questions customers ask us about our cable blowing machines — so you can make the best choice for your projects.

1. Why choose blowing instead of pulling?

Cable blowing machines are faster, safer, and more efficient than traditional pulling. They reduce friction, protect the cable from damage, and often require just one operator. The cable glides smoothly through the duct, even around bends, without strain.

2. Which machine is right for our cable size?

Here’s a quick guide:

1–6 mm cables → DrillSKY, MicroSKY, or MiniSKY
6–24 mm cables → SKYJET
Heavy-duty, 6–24 mm → HydroSKY or HydroSKY + Honda GX270 HPU

Choosing the correct model ensures smooth operation and maximum efficiency from your cable blowing machines.

3. How do I select the right cable blowing machine?

Two main factors matter:

Cable and duct diameter – If they don’t match, the job will slow down or stop.
Airflow and pressure capacity – Enough to move the cable without damaging it.

4. What’s the best speed and pressure for blowing?

Start at a low speed and gradually increase the air pressure. Too much pressure can harm the cable; too little means it won’t move. Keep an eye on vibrations and speed to maintain smooth progress when using cable blowing machines.

5. How far can a cable blowing machine push a cable?

With the right setup, reaching 2,500 meters is common—and under ideal conditions, up to 3,100 meters is possible.

6. What’s the difference between hydraulic and pneumatic machines?

Pneumatic (air-powered): Lightweight, low maintenance, ideal for small to medium cables.
Hydraulic (HydroSKY): Stronger, built for large cables and high-performance jobs.

7. Will the cable be damaged during blowing?

No—when using a proper cable blowing machine, the cable is propelled with air or water, which greatly reduces friction. This prevents bends, kinks, or mechanical stress.

8. Do ducts need to be clean before blowing?

Absolutely. Dust, dirt, or burrs inside the duct can slow down or block the cable. Always clean and inspect ducts before starting for a trouble-free installation.
