Electric vs Pneumatic vs Hydraulic Water Cannons: Which One Fits Your Fleet?

Electric vs Pneumatic vs Hydraulic Water Cannons: Which One Fits Your Fleet?

When you need throw distance, torque, and durability, hydraulic cannons are the top-tier choice. Magnum and T-Rex both offer robust hydraulic models built for industrial work. These systems tap into the vehicle’s hydraulic circuit or PTO for high-speed, high-force control.

What works:

Serious reach and control — perfect for long throw and firefighting-style outputs

Fast and responsive — smooth joystick or remote actuation

Built for abuse — stands up to constant use, rough terrain, and heavy vibration

Where they fall short:

Higher install and component cost

Complex setup — needs hydraulic power and proper return plumbing

More moving parts to maintain — regular hose and seal checks are a must

Best for: Mining, high-volume dust suppression, remote access sites, or any job where the cannon can’t be the weak point.


At-a-Glance Comparison

Drive Type Electric Pneumatic Hydraulic
Power Source 12V/24V DC Compressed air Hydraulic pump (PTO or aux)
Control Switch/remote Air valve / solenoid Joystick/remote
Power Output Moderate Moderate High
Speed Medium Slower Fast
Durability Good if seals hold — water-sensitive Excellent — low electronics High — built for abuse
Maintenance Low — check seals Medium — air system care High — hoses, fittings, fluid
Cost $$ $$$ (mid-range) $$$$ (highest)
Best Use Civil works, road crews Harsh/wet sites needing simplicity Mining, fire, long-range washdown

Supply Chain Matters: Local Brands Make a Difference

Both T-Rex and Magnum are Australian-based suppliers, which makes a big difference when it comes to:

Faster delivery

Readily available spare parts

Hands-on aftermarket support

In a world of long lead times and offshore delays, local support can keep your trucks working when others are parked. If you're running a fleet that can't afford downtime, that's something to factor in.


Final Word

Every site’s different — and every truck needs a cannon that fits the job, not just the budget.

Electric is great if you want plug-and-play simplicity

Pneumatic is your go-to if you're working in tough spray zones

Hydraulic is what you reach for when you need power, speed, and reliability without compromise

If you're scoping out a build, upgrading a fleet, or troubleshooting a system that keeps letting you down, get in touch. We’ll help you choose something that fits the conditions — not just the catalogue.

Because at Any Type Trucks, we don’t just sell them. We run them, fix them, and stand behind them.
