Baffle balls, for a steadier load.
Baffle balls cut fluid surge for greater stability when cornering and braking, in any type of tank.
Less surge, more control.
Liquid in a moving tank surges as you brake and corner. Baffle balls deflect that surge, so the load stays steadier.

Baffle balls, explained.
Liquid in a part-full tank keeps moving after the vehicle does. That surge slams into the tank walls when you brake, corner or pull away, and you feel it through the whole vehicle. Promax Baffle Balls fill the tank and deflect the surge, giving greater stability when cornering and braking. Here is how they help, which size to choose and how to fit them.
Where Baffle Balls Get Used
- Water carts and dust suppression units
- Ute and trailer transport tanks
- Truck-mounted water tanks
- Polyethylene, steel, fibreglass and aluminium tanks
What They Do
- Improve braking by up to 46%
- Give greater stability when cornering and braking
- Reduce wear and tear on the truck, and can lead to savings on road wear and vehicle maintenance
- Lightweight and durable, with no rust
- Food grade material, suitable for potable water
Fit Them To Any Tank
Installation is simple: clip them together and place them in the tank. Only a small opening is needed, so you can add them to tanks you already run as well as new ones, whatever the tank is made from.
Promax slip-on dust suppression units come fully baffled with the Ball Baffle System as standard. On Promax transport tanks they are an option.
Which Size
Both sizes do the same job. The difference is how many you need and how much water they take up.
| Size | How many | Displacement | Weight |
|---|---|---|---|
| 195mm | About 1 per 7L of tank capacity | 150ml each | 120g each |
| 355mm | About 1 per 40L of tank capacity | 428ml each | 386g each |
For example, a 1,000L tank takes about 143 of the 195mm balls or 25 of the 355mm balls. Use the calculator above for your own tank.
