Fiber Optic Cable Blowers

Blower Application
FIber Optic Cable Blower Patent #6,012,621
See More Here

The  Fiber Optic Cable Blower offers what you’d expect from Condux, and more. More speed and more push force monitoring for example. After all, the faster and safer that fiber is installed in the duct, the more money in your pocket.

Install 300 feet of fiber optic cable per minute (90 m/min) with the new Condux Fiber Optic Cable Blower. Condux engineers designed the speed in by making the cable travel at the same speed as the air! A missile is always attached to the front of the cable. Compressed air propels the missile and cable through the airtight sealed duct in a matter of seconds. And, because air flow and tractor drive speed can be adjusted, you can install fiber at the rate which best suits any application.

Compared to other models on the market, the Condux Fiber Optic Cable Blower features longer tractor feed grip area for less stress on the cable. Condux incorporates a hydraulic cylinder on the tractor feed to better control down pressure.

A refined speed and distance counter with LCD read-out, as well as convenient hydraulic and pneumatic controls, come standard with the Condux blower. An optional electronic control system is available to monitor the cable and tractor drive speeds. This system will shut down the blower if cable slippage, an over-speed situation, or a cable stoppage is detected. When you compare features and quality you’ll see why the Condux Fiber Optic Cable Blower is better.

The Condux Fiber Optic Cable Blower now offers softer tracks, collapsible legs, improved hydraulic cylinder mounts on the tractor feed and improved counter rollers. The new tracks reduce noise, vibration, allow better cable grip and provide a better pushing force.

The collapsible legs allow a lower profile for transporting and storing the blower and the flexibility to set up the Fiber Optic Cable Blower at a 45 degree angle for easier connection to the duct.

The hydraulic cylinder mounts stabilize the upper tractor feed by keeping it square when it is lowered into position, thus preventing excess wear on the tracks.

The new counter rollers, along with reinforced joints, help improve counter accuracy.

Blower Application

LW Fiber Optic Cable Blower: While Condux’s new LW Fiber Optic Cable Blower operates on the same principles as the HD model, there are several differences. The new LW Fiber Optic Cable Blower is compact and lightweight, making it ideally suited for your most difficult job sites and “last mile” fiber installations. An updated design has increased portability and made operation easier than ever. In addition, Condux’s patented traction control system shuts down the blower when problems with cable slippage or duct blockage are detected, adding safety to every job and preventing costly cable damage.

Backed by years of fiber blowing experience, the LW Fiber Optic Cable Blower is designed for the installation of fiber optic cables with diameters from 0.23" (5.8 mm) to 1.13" (28.7 mm) into innerduct from 0.98" (25 mm) outer diameter to 1.97" (50.0 mm) outer diameter. Installation speeds approaching 300 ft/min (91.5 m/min) are possible.

Versatility
The Condux Fiber Optic Cable Blower operates efficiently with most common combinations of cable and innerduct sizes. The Fiber Optic Cable Blower is designed for the installation of fiber optic cables with diameters from 0.23" (5.8 mm) to 1.13" (28.7 mm) into innerduct from 0.98" (25 mm) outer diameter to 1.97" (50.0 mm) outer diameter. The correct size cable seals, feed tube and venturi must be determined for the cable being installed. Also necessary are the correct size innerduct seals, clamps and carrier for the innerduct being occupied. Use the charts on page 108 to determine the correct size components for your specific cable and innerduct installation project. Use both the size and color reference to ensure the correct selection each time the Cable Blower is used.
