V4 Grizzon™ – Power Meets Precision

V4 Grizzon sets a new standard in fiber blowing technology. At its core lies a patent pending dual-gear system that allows you to switch instantly between high speed and extreme pushing force, depending on the conditions of the installation.
Whether you need fast progress on open routes or high torque in demanding environments, the V4 Grizzon delivers both — seamlessly.

Compact Yet Exceptionally Strong

Despite its lightweight and compact design (approx. 31 kg), the V4 Grizzon is built for heavy-duty performance. It combines double pneumatic motors with a durable anodized aluminum frame, offering up to 2000 N pushing force in low-gear mode and speeds up to 110 m/min in high gear.
This makes it one of the most powerful and robust fiber blowing machines in its class — ready for everyday professional use.

Designed for Flexibility

The V4 Grizzon is more than just a fiber blower. It’s a multifunctional machine that supports:

Floating technology – for long-distance installations using water and air
Push/Pull rod operations – when combined with the Jetting Cart
Sub-ducting – designed to handle various duct and fiber sizes.

Whatever the setup, the V4 Grizzon adapts quickly and efficiently, making it the go-to solution for diverse field conditions.

Wide Compatibility

Supporting fiber cables from 4 to 40 mm and ducts from 10 to 63 mm, the V4 Grizzon™ gives installers the freedom to handle everything from small projects to large backbone installations — with just one machine.

Smart and Simple Operation

Equipped with a joystick controller for precise forward/reverse movement and a digital display that monitors speed, distance, and pressure, the V4 Grizzon is designed to make installation intuitive and safe.
Its adjustable clamping system ensures gentle, long-contact grip on the cable, minimizing the risk of damage while maximizing traction.

The V4 Grizzon also features an integrated Wi-Fi interface, giving users direct access to the machine’s settings and firmware. Through the built-in web interface, firmware updates can easily be downloaded and installed, ensuring the machine is always up to date with the latest improvements and features.

For easy maintenance, the machine features a Quick Release Belt Drive system — simply release the two tension arms, and the drive belts can be replaced in seconds without tools or disassembly.

Ready for Every Project

From long-distance floating to sub-ducting in tight manholes, the V4 Grizzon™ is made for real-world conditions. Setup is fast and straightforward, and the machine integrates perfectly with JetLogger for detailed installation documentation and JetLuber for precise lubrication control — creating a smooth, efficient, and data-driven fiber installation process.
