Turbo 2 Mechanical Roof Ventilator – Wind-Powered Vehicle Ventilation Without Electricity

The G&C Turbo 2 mechanical roof ventilator is a wind-driven extraction fan designed for commercial vans, campervans, service vehicles, trailers and enclosed vehicle cargo areas. Airflow generated while driving causes the ventilator to rotate, helping remove warm, humid and stale air from the vehicle.

The Turbo 2 operates without an electrical connection. No battery, wiring or switch is required. It can also operate while the vehicle is stationary when sufficient natural wind is available.

With an external mounting height of just 68 mm, the Turbo 2 features a relatively low-profile design. It is available in black and white and comes with a closable interior grille for a neat finish.

Always check the available roof space and installation instructions before cutting the vehicle roof. Actual airflow depends on wind conditions, installation and available replacement air.

How Does the Turbo 2 Work?

Air moving around the roof ventilator causes the rotating cover to turn, extracting air from the vehicle interior.

The Turbo 2 does not contain an electric motor. Its extraction performance therefore varies with driving wind and natural wind. Constant extraction cannot be guaranteed in completely still conditions.

The included interior shutter allows the ventilation opening to be opened or closed manually.

Suitable Vehicle Applications

• Commercial vans: Additional ventilation for enclosed cargo areas.
• Service vehicles: Air extraction while driving or in sufficient natural wind.
• Campervans: Supplementary ventilation without electrical power.
• Enclosed trailers: Air exchange in cargo compartments.
• Animal transport vehicles: A possible component of a properly designed ventilation system, not a replacement for adequate temperature and climate control.

Roof Installation

The Turbo 2 requires a Ø128 mm roof opening. The standard mounting kit accommodates roof thicknesses from 1 to 21 mm.

Check that the 319 mm rotating cover has sufficient clearance from roof racks, solar panels and other accessories.

Follow the installation instructions and use suitable sealing materials. Ribbed or uneven roofs may require an additional roof adapter.

Why Is Additional Floor Ventilation Useful?

Extracted air must be replaced by air entering the vehicle. A suitable floor ventilation grille can provide an additional air inlet and support circulation through the cargo compartment.

Turbo 2 vs Electric Roof Ventilation

The Turbo 2 requires no electrical power, but airflow depends on available wind. An electric 12V or 24V roof ventilator is more suitable when active extraction is required even without wind.
