Protect Your Equipment and Improve Results
It’s true that the Tegras Centraliser is a requirement for ducts over 400mm. That said, it is also one of the smartest investments you can make for the longevity of your Tegras Eon machine.
Stabilising the brush head prevents the shaft from dragging along the bottom of the duct. It also stops it from “whipping” against the sides during high-speed rotation. This significantly reduces friction and wear on the shaft’s outer casing. As a result, it extends the lifespan of your most expensive consumable.
Why Stability Matters for TR19® Compliance
In larger ductwork, gravity naturally pulls a rotary brush to the floor of the duct. Without a centraliser, this results in:
- Uneven Cleaning: The bottom of the duct gets scrubbed aggressively, while the top and corners receive very little contact.
- Lost Efficiency: Operators have to work harder and slower to manipulate the shaft to reach the upper surfaces.
The Tegras Centraliser Eon solves this instantly by suspending the brush in the exact centre of the airway. This ensures the bristles apply equal pressure to all four sides of the duct. As a result, you can pass inspection on the first run.
Key Features:
- Tool-Free Adjustment: The scissor-action or sliding mechanism allows operators to adjust the diameter in seconds. This eliminates the need for spanners or screwdrivers. It’s perfect for jobs with varying duct sizes.
- Smooth Navigation: The nylon runners are designed to glide over duct joints and rivets. This prevents the cleaning head from getting snagged or stuck deep inside the system.
- Optimised for Eon: Specifically balanced for the torque and speed of the Tegras Eon motor. This ensures smooth rotation without vibration.
- Professional Tip: Always use the Centraliser when working on vertical risers. This prevents the brush from leaning against one side of the wall. The end result is a uniform clean from top to bottom.
